COVID-19 Vaccine Janssen is indicated for active immunisation to prevent COVID-19 caused by SARS-CoV-2 in individuals 18 years of age and older.

The use of this vaccine should be in accordance with official recommendations.

Posology

Individuals 18 years of age and older

Primary vaccination

COVID-19 Vaccine Janssen is administered as a single-dose of 0.5 mL by intramuscular injection only.

Booster dose

A booster dose (second dose) of 0.5 mL of COVID-19 Vaccine Janssen may be administered intramuscularly at least 2 months after the primary vaccination in individuals 18 years of age and older (see also sections 4.4, 4.8 and 5.1).

Paediatric population

The safety and efficacy of COVID-19 Vaccine Janssen in children and adolescents (less than 18 years of age) have not yet been established. No data are available.

Elderly

No dose adjustment is required in elderly individuals ≥ 65 years of age. See also sections 4.8 and 5.1.

Method of administration

COVID-19 Vaccine Janssen is for intramuscular injection only, preferably in the deltoid muscle of the upper arm.

The vaccine should not be mixed in the same syringe with any other vaccines or medicinal products.

For precautions to be taken before administering the vaccine, see section 4.4.

For instructions on handling and disposal of the vaccine, see section 6.6.

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

A history of confirmed thrombosis with thrombocytopenia syndrome (TTS) following vaccination with COVID-19 Vaccine Janssen (see also section 4.4).

Individuals who have previously experienced episodes of capillary leak syndrome (CLS) (see also section 4.4).

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of the administered product should be clearly recorded.

Hypersensitivity and anaphylaxis

Events of anaphylaxis have been reported. Appropriate medical treatment and supervision should always be readily available in case of an anaphylactic reaction following the administration of the vaccine. Close observation for at least 15 minutes is recommended following vaccination.

Anxiety-related reactions

Anxiety-related reactions, including vasovagal reactions (syncope), hyperventilation or stress‐related reactions may occur in association with vaccination as a psychogenic response to the needle injection. It is important that precautions are in place to avoid injury from fainting.

Concurrent illness

Vaccination should be postponed in individuals suffering from an acute severe febrile illness or acute infection. However, the presence of a minor infection and/or low-grade fever should not delay vaccination.

Coagulation disorders

• Thrombosis with thrombocytopenia syndrome: A combination of thrombosis and thrombocytopenia, in some cases accompanied by bleeding, has been observed very rarely following vaccination with COVID-19 Vaccine Janssen. This includes severe cases of venous thrombosis at unusual sites such as cerebral venous sinus thrombosis (CVST), splanchnic vein thrombosis as well as arterial thrombosis concomitant with thrombocytopenia. Fatal outcome has been reported. These cases occurred within the first three weeks following vaccination, and mostly in individuals under 60 years of age.

Thrombosis in combination with thrombocytopenia requires specialised clinical management. Healthcare professionals should consult applicable guidance and/or consult specialists (e.g., haematologists, specialists in coagulation) to diagnose and treat this condition.

Individuals who have experienced thrombosis with thrombocytopenia syndrome following vaccination with COVID-19 Vaccine Janssen should not receive COVID-19 Vaccine Janssen (See also section 4.3).

Individuals with a history of heparin-induced thrombocytopenia and thrombosis (HITT or HIT type 2) should only receive the COVID-19 Vaccine Janssen if the potential benefits outweigh the potential risks.

• Venous thromboembolism: Venous thromboembolism (VTE) has been observed rarely following vaccination with COVID-19 Vaccine Janssen (see section 4.8). This should be considered for individuals at increased risk for VTE.

• Immune thrombocytopenia: Cases of immune thrombocytopenia with very low platelet levels (<20000 per μL) have been reported very rarely after vaccination with COVID-19 Vaccine Janssen, usually within the first four weeks after receiving COVID-19 Vaccine Janssen. This included cases with bleeding and cases with fatal outcome. Some of these cases occurred in individuals with a history of immune thrombocytopenia (ITP). If an individual has a history of ITP, the risks of developing low platelet levels should be considered before vaccination, and platelet monitoring is recommended after vaccination.

Healthcare professionals should be alert to the signs and symptoms of thromboembolism and/or thrombocytopenia. Those vaccinated should be instructed to seek immediate medical attention if they develop symptoms such as shortness of breath, chest pain, leg pain, leg swelling, or persistent abdominal pain following vaccination. Additionally, anyone with neurological symptoms including severe or persistent headaches, seizures, mental status changes or blurred vision after vaccination, or who experiences spontaneous bleeding, skin bruising (petechia) beyond the site of vaccination after a few days, should seek prompt medical attention.

Individuals diagnosed with thrombocytopenia within 3 weeks after vaccination with COVID-19 Vaccine Janssen should be actively investigated for signs of thrombosis. Similarly, individuals who present with thrombosis within 3 weeks of vaccination should be evaluated for thrombocytopenia.

Risk of bleeding with intramuscular administration

As with other intramuscular injections, the vaccine should be given with caution in individuals receiving anticoagulant therapy or those with thrombocytopenia or any coagulation disorder (such as haemophilia) because bleeding or bruising may occur following an intramuscular administration in these individuals.

Capillary leak syndrome

Very rare cases of capillary leak syndrome (CLS) have been reported in the first days after vaccination with COVID-19 Vaccine Janssen, in some cases with a fatal outcome. A history of CLS has been reported. CLS is a rare disorder characterised by acute episodes of oedema mainly affecting the limbs, hypotension, haemoconcentration and hypoalbuminaemia. Patients with an acute episode of CLS following vaccination require prompt recognition and treatment. Intensive supportive therapy is usually warranted. Individuals with a known history of CLS should not be vaccinated with this vaccine. See also section 4.3.

Guillain-Barré syndrome and transverse myelitis

Guillain-Barré syndrome (GBS) and transverse myelitis (TM) have been reported very rarely following vaccination with COVID-19 Vaccine Janssen. Healthcare professionals should be alert to GBS and TM signs and symptoms to ensure correct diagnosis, in order to initiate adequate supportive care and treatment and to rule out other causes.

Myocarditis and pericarditis

There is an increased risk of myocarditis and pericarditis following vaccination with COVID-19 Vaccine Janssen (section 4.8 ). These conditions can develop within just a few days after vaccination and have primarily occurred within 14 days. They have been observed more often in males younger than 40 years of age.

Healthcare professionals should be alert to the signs and symptoms of myocarditis and pericarditis. Vaccinees should be instructed to seek immediate medical attention if they develop symptoms indicative of myocarditis or pericarditis such as (acute and persisting) chest pain, shortness of breath, or palpitations following vaccination. Healthcare professionals should consult guidance and/or specialists to diagnose and treat these conditions.

Risk of severe adverse events after a booster dose

The risk of severe adverse events (such as coagulation disorders including thrombosis with thrombocytopenia syndrome, CLS, GBS, myocarditis and pericarditis) after a booster dose of COVID-19 Vaccine Janssen has not yet been characterised.

Immunocompromised individuals

The efficacy, safety and immunogenicity of the vaccine have not been assessed in immunocompromised individuals, including those receiving immunosuppressant therapy.

The efficacy of COVID-19 Vaccine Janssen may be lower in immunosuppressed individuals.

Duration of protection

The duration of protection afforded by the vaccine is unknown as it is still being determined by ongoing clinical trials.

Limitations of vaccine effectiveness

Protection starts around 14 days after vaccination. As with all vaccines, vaccination with COVID-19 Vaccine Janssen may not protect all vaccine recipients (see section 5.1).

Excipients

Sodium

This medicinal product contains less than 1 mmol sodium (23 mg) per 0.5 mL dose, that is to say essentially 'sodium-free'.

Ethanol

This medicinal product contains 2 mg of alcohol (ethanol) per 0.5 mL dose. The small amount of alcohol in this medicinal product will not have any noticeable effects.

No interaction studies have been performed. Concomitant administration of COVID-19 Vaccine Janssen with other vaccines has not been studied.

Pregnancy

There is limited experience with the use of COVID-19 Vaccine Janssen in pregnant women. Animal studies with COVID-19 Vaccine Janssen do not indicate direct or indirect harmful effects with respect to pregnancy, embryo/foetal development, parturition or postnatal development (see section 5.3).

Administration of COVID-19 Vaccine Janssen in pregnancy should only be considered when the potential benefits outweigh any potential risks to the mother and foetus.

Breast-feeding

It is unknown whether COVID-19 Vaccine Janssen is excreted in human milk.

Fertility

Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).

COVID-19 Vaccine Janssen has no or negligible influence on the ability to drive and use machines. However, some of the adverse reactions mentioned under section 4.8 may temporarily affect the ability to drive or use machines.

Summary of safety profile

Primary vaccination (primary pooled analysis)

The safety of COVID-19 Vaccine Janssen was evaluated in the primary pooled analysis from the double-blind phase of the randomised, placebo-controlled studies COV1001, COV1002, COV2001, COV3001 and COV3009. A total of 38,538 adults aged 18 years and older received at least a single-dose primary vaccination of COVID-19 Vaccine Janssen. The median age of individuals was 52 years (range 18-100 years). For the primary pooled analysis, the median follow-up for individuals who received COVID-19 Vaccine Janssen was approximately 4 months after completion of primary vaccination. Longer safety follow-up of ≥ 6 months is available for 6,136 adults who received COVID-19 Vaccine Janssen.

In the primary pooled analysis, the most common local adverse reactions reported was injection site pain (54.3%). The most common systemic adverse reactions were fatigue (44.0%), headache (43.0%), myalgia (38.1%) and nausea (16.9%). Pyrexia (defined as body temperature ≥ 38.0°C) was observed in 7.2% of participants. Most adverse reactions were mild to moderate in severity. Across the studies, most adverse reactions occurred within 1–2 days following vaccination and were of short duration (1–2 days).

Reactogenicity was generally milder and reported less frequently in older adults.

The safety profile was generally consistent across participants with or without prior evidence of SARS-CoV-2 infection at baseline. A total of 10.6% of individuals that received COVID-19 Vaccine Janssen were SARS-CoV-2 positive at baseline (based on serology or RT-PCR assessment).

Booster dose (second dose) following primary vaccination with COVID-19 Vaccine Janssen

The safety of a booster dose (second dose) with COVID-19 Vaccine Janssen administered approximately 2 months after the primary vaccination was evaluated in an ongoing randomised, double-blind, placebo-controlled Phase 3 Study (COV3009). In the FAS (full analysis set), from the 15708 adults aged 18 years and older who received 1 dose of COVID 19 Vaccine Janssen, a total of 8646 individuals received a second dose during the double-blind phase. In the reactogenicity subset, from the 3016 individuals who received 1 dose of COVID-19 Vaccine Janssen, 1559 individuals received a second dose during the double-blind phase. The median age of individuals was 53.0 years (range: 18-99 years). At the data-cut off (25 June 2021), the median follow-up duration after the booster dose with COVID-19 Vaccine Janssen was 38 days. The solicited adverse reaction profile for the booster dose was similar to that after the first dose. There were no new safety signals identified.

Tabulated list of adverse reactions

Adverse drug reactions observed in the primary pooled analysis or from post marketing sources are organised by MedDRA System Organ Class (SOC). Frequency categories are defined as follows:

Very common (≥ 1/10);

Common (≥ 1/100 to < 1/10);

Uncommon (≥ 1/1000 to < 1/100);

Rare (≥ 1/10000 to < 1/1000);

Very rare (< 1/10000);

Not known (cannot be estimated from the available data).

Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. If you are concerned about an adverse event, it should be reported on a Yellow Card. Reporting forms and information can be found at https://coronavirus-yellowcard.mhra.gov.uk/ or search for MHRA Yellow Card in the Google Play or Apple App Store and include the vaccine brand and batch/Lot number if available. Alternatively, adverse events of concern in association with COVID-19 Vaccine Janssen can be reported to Janssen on +44 1 494 567 444 or visit the URL: www.covid19vaccinejanssen.com

Please do not report the same adverse event(s) to both systems as all reports will be shared between Janssen and MHRA (in an anonymised form) and dual reporting will create unnecessary duplicates.

No case of overdose has been reported. In Phase 1/2 studies where a higher dose (up to 2-fold) was administered COVID-19 Vaccine Janssen remained well-tolerated, however vaccinated individuals reported an increase in reactogenicity (increased vaccination site pain, fatigue, headache, myalgia, nausea and pyrexia).

In the event of overdose, monitoring of vital functions and possible symptomatic treatment is recommended.

Pharmacotherapeutic group: COVID-19, viral vector, non-replicating, ATC code: J07BN02

Mechanism of action

COVID-19 Vaccine Janssen is a monovalent vaccine composed of a recombinant, replication-incompetent human adenovirus type 26 vector that encodes a SARS-CoV-2 full-length spike (S) glycoprotein in a stabilised conformation. Following administration, the S glycoprotein of SARS-CoV-2 is transiently expressed, stimulating both neutralising and other functional S-specific antibodies, as well as cellular immune responses directed against the S antigen, which may contribute to protection against COVID-19.

Clinical efficacy

Efficacy from a single-dose primary vaccination

Primary analysis

A primary analysis (cut-off date 22 January 2021) of a multicentre, randomised, double-blind, placebo-controlled Phase 3 study (COV3001) was conducted in the United States, South Africa and Latin American countries to assess the efficacy, safety, and immunogenicity of a single-dose primary vaccination of COVID-19 Vaccine Janssen for the prevention of COVID-19 in adults aged 18 years and older. The study excluded individuals with abnormal function of the immune system resulting from a clinical condition, individuals who are under immunosuppressive therapies within 6 months, as well as pregnant women. Participants with stable HIV infection under treatment were not excluded. Licensed vaccines, excluding live vaccines, could be administered more than 14 days before or more than 14 days after the vaccination in the study. Licensed live attenuated vaccines could be administered more than 28 days before or more than 28 days after the vaccination in the study.

A total of 44325 individuals were randomised in parallel in a 1:1 ratio to receive an intramuscular injection of COVID-19 Vaccine Janssen or placebo. A total of 21895 adults received COVID-19 Vaccine Janssen and 21888 adults received placebo. Participants were followed for a median follow-up of approximately 2 months after vaccination.

The primary efficacy analysis population of 39321 individuals included 38059 SARS-CoV-2 seronegative individuals at baseline and 1262 individuals with an unknown serostatus.

Demographic and baseline characteristics were similar among individuals who received the COVID-19 Vaccine Janssen and those who received placebo. In the primary efficacy analysis population, among the individuals who received COVID-19 Vaccine Janssen, the median age was 52.0 years (range: 18 to 100 years); 79.7% (N=15646) of individuals were 18 to 64 years old [with 20.3% (N=3984) aged 65 or older and 3.8% (N=755) aged 75 or older]; 44.3% of individuals were female; 46.8% were from Northern America (United States), 40.6% were from Latin America and 12.6% were from Southern Africa (South Africa). A total of 7830 (39.9%) individuals had at least one pre-existing comorbidity associated with increased risk of progression to severe COVID-19 at baseline. Comorbidities included: obesity defined as BMI ≥ 30 kg/m² (27.5%), hypertension (10.3%), type 2 diabetes (7.2%), stable/well-controlled HIV infection (2.5%), serious heart conditions (2.4%) and asthma (1.3%). Other comorbidities were present in ≤ 1% of the individuals.

COVID-19 cases were confirmed by a central laboratory based on a positive SARS-CoV-2 viral RNA result using a polymerase chain reaction (PCR)-based test. Vaccine efficacy overall and by key age groups are presented in Table 2.

Vaccine efficacy against severe COVID-19 is presented in Table 3 below.

Of the 14 vs. 60 severe cases with onset at least 14 days after vaccination in the COVID-19 Vaccine Janssen group vs. placebo group, 2 vs. 6 were hospitalised. Three individuals died (all in the placebo group). The majority of the remaining severe cases fulfilled only the oxygen saturation (SpO₂) criterion for severe disease (≤ 93% on room air).

Updated analyses

The updated efficacy analyses at the end of the double-blind phase (cut-off date 09 July 2021) were performed with additional confirmed COVID-19 cases accrued during blinded, placebo-controlled follow-up, with a median follow-up of 4 months after a single-dose of the COVID-19 Vaccine Janssen.

Beyond 14 days after vaccination, 18 vs. 74 cases of molecularly confirmed COVID-19 were hospitalised, respectively in the COVID-19 Vaccine Janssen vs. placebo group, resulting in 76.1% (adjusted 95% CI: 56.9; 87.7) vaccine efficacy. A total of 5 cases in the COVID-19 Vaccine Janssen group vs. 17 cases in the placebo group required Intensive Care Unit (ICU) admission and 4 vs. 8 cases in the COVID-19 Vaccine Janssen and placebo group respectively required mechanical ventilation.

Vaccine efficacy against asymptomatic infections at least 28 days after vaccination was 28.9% (95% CI: 20.0; 36.8) and against all SARS-CoV-2 infections was 41.7% (95% CI: 36.3; 46.7).

Subgroup analyses of the primary efficacy endpoint showed similar efficacy point estimates for male and female participants, as well as for participants with and without medical comorbidities associated with high risk of severe COVID-19.

A summary of vaccine efficacy by variant strain is presented in Table 5 below:

Efficacy of two-doses of COVID-19 Vaccine Janssen administered 2 months apart

A final analysis (cut-off date 25 June 2021) of a multicenter, randomised, double-blind, placebo-controlled Phase 3 study (COV3009) was conducted in North and Latin America, Africa, Europe and Asia to assess the efficacy, safety, and immunogenicity of 2 doses of COVID-19 Vaccine Janssen administered with a 56-day interval. The study excluded individuals with abnormal function of the immune system resulting from a clinical condition, individuals who were under immunosuppressive therapies within 6 months, as well as pregnant women. Participants with stable HIV infection under treatment were not excluded. Licensed vaccines, excluding live vaccines, could be administered more than 14 days before or more than 14 days after the vaccination in the study. Licensed live attenuated vaccines could be administered more than 28 days before or more than 28 days after the vaccination in the study.

A total of 31300 individuals were randomised in the double-blind phase of the study. In total, 14492 (46.3%) individuals were included in the per-protocol efficacy population (7484 individuals received COVID-19 Vaccine Janssen and 7008 individuals received placebo). Participants were followed for a median of 36 days (range: 0-172 days) after vaccination.

Demographic and baseline characteristics were similar among individuals who received at least two doses of the COVID-19 Vaccine Janssen and those who received placebo. In the primary efficacy analysis population, among the individuals who received 2 doses of COVID-19 Vaccine Janssen, the median age was 50.0 years (range: 18 to 99 years); 87.0% (N=6512) of individuals were 18 to 64 years old [with 13.0% (N=972) aged 65 or older and 1.9% (N=144) aged 75 or older]; 45.4% of individuals were female; 37.5% were from North America (United States), 51.0% were from Europe (including UK), 5.4% were from South Africa, 1.9% from Philippines and 4.2% from Latin America. A total of 2747 (36.7%) individuals had at least one pre-existing comorbidity associated with increased risk of progression to severe COVID-19 at baseline. Comorbidities included: obesity defined as BMI ≥ 30 kg/m² (24.6%), hypertension (8.9%), sleep apnea (6.7%), type 2 diabetes (5.2%), serious heart conditions (3.6%), asthma (1.7%) and stable/well-controlled HIV infection (1.3%). Other comorbidities were present in ≤ 1% of the individuals.

Vaccine efficacy against symptomatic COVID-19 and severe COVID-19 is presented in Table 6 below:

Approximately 68% of centrally confirmed strains have been sequenced as of this analysis (July 2021). Preliminary analysis results of variants with sufficient cases available for meaningful interpretations (Alpha [B.1.1.7] and Mu [B.1.621]) show that, after the first dose of COVID-19 Vaccine Janssen, efficacy 14 days post-dose 1 (Day 15-Day 56) for these 2 variants was 71.6% [95% CI: 43.2; 86.9] and 43.9% [95% CI: -43.4; 79.6], respectively. After the second dose (≥71 days), efficacy for Alpha and Mu was 94.2% [95% CI: 62.9; 99.9] and 63.1% [95% CI: -27.9; 91.6], respectively. Therefore, statistically significant efficacy for Mu was not demonstrated. There were only few Delta cases (2 and 1 in the COVID-19 Vaccine Janssen group and placebo group, respectively) and no reference strain cases in either the COVID-19 Vaccine Janssen or placebo group in the follow-up 14 days after the booster dose (≥71 days).

Vaccine efficacy against asymptomatic infections at least 14 days after second vaccination was 34.2% (95% CI: -6.4; 59.8).

Immunogenicity of a booster dose (second dose) following primary vaccination with COVID-19 Vaccine Janssen

It should be noted that there is no established immune correlate of protection. In a Phase 2 Study (COV2001), individuals 18 through 55 years of age and 65 years and older received a booster dose of the COVID-19 Vaccine Janssen approximately 2 months after the primary vaccination. Immunogenicity was assessed by measuring neutralising antibodies to SARS-CoV-2 Victoria/1/2020 strain using a qualified wild-type virus neutralisation assay (wtVNA). Immunogenicity data are available from 39 individuals, of whom 15 were 65 years of age and older, and are summarised in Table 7.

Neutralising antibody and binding antibody increases against the reference SARS-CoV-2 strain were also observed in studies COV1001, COV1002 and COV2001 in a limited number of study participants after a boost given at 2, 3 and 6 months, when compared to pre-boost values. Overall, the increases of GMTs pre-boost to 1 month post-boost ranged from 1.5 to 4.4 fold for neutralising antibodies, and from 2.5 to 5.8 fold for binding antibodies. A 2-fold decrease in antibody levels was observed 4 months following 2-month booster dose, compared to 1 month following 2-month booster dose. Ab levels were still higher than antibody levels following a single-dose at a similar timepoint. These data support the administration of a booster dose when administered at an interval of 2 months or longer after primary vaccination.

Elderly population

COVID-19 Vaccine Janssen was assessed in individuals 18 years of age and older. The efficacy of COVID-19 Vaccine Janssen was consistent between elderly (≥ 65 years) and younger individuals (18-64 years).

Paediatric population

The licensing authority has deferred the obligation to submit the results of studies with COVID-19 Vaccine Janssen in one or more subsets of the paediatric population in prevention of COVID-19 (see section 4.2 for information on paediatric use).

Not applicable.

Non-clinical data reveal no special hazards for humans based on conventional studies of repeat-dose toxicity and local tolerance, and reproductive and developmental toxicity.

Genotoxicity and carcinogenicity

COVID-19 Vaccine Janssen has not been evaluated for its genotoxic or carcinogenic potential. The components of the vaccine are not expected to have genotoxic or carcinogenic potential.

Reproductive toxicity and fertility

Female reproductive toxicity and fertility were assessed in a combined embryo-foetal and pre- and post-natal development study in the rabbit. In this study a first vaccination of COVID-19 Vaccine Janssen was administered intramuscularly to female rabbits 7 days prior to mating, at a dose equivalent to 2-fold above the recommended human dose, followed by two vaccinations at the same dose during the gestation period (i.e., at gestational days 6 and 20). There were no vaccine-related effects on female fertility, pregnancy, or embryo-foetal or offspring development. The parental females as well as their foetuses and offspring exhibited SARS-CoV-2 S protein-specific antibody titres, indicating that maternal antibodies were transferred to the foetuses during gestation. No COVID-19 Vaccine Janssen data are available on vaccine excretion in milk.

In addition, a conventional (repeat-dose) toxicity study in rabbits with COVID-19 Vaccine Janssen did not reveal any effects on male sex organs that would impair male fertility.
