COVID-19 Vaccine Janssen (Johnson & Johnson) Description

The Johnson & Johnson Janssen COVID-19 (Ad26.COV2.S) single-shot experimental vaccine leverages Janssen's AdVac and PER.C6® technologies. Janssen’s AdVac® vectors are based on a specific type of adenovirus, which has been genetically modified so that it can no longer replicate in humans and cause disease. Adenoviruses are a group of viruses that can cause the common cold.

The AdVac® technology works by using an adenovirus as a vector of an antigen’s genetic code to mimic components of a pathogen. Antigens are produced to mimic the pathogen without causing severe disease. The Janssen AdVac viral vector technology can induce potent and long-lasting humoral and cellular immune responses, enabling the pursuit of vaccines for disease targets currently unpreventable or untreatable. These are the same technologies Janssen used to develop and manufacture the Ebola vaccine, Ad26.ZEBOV.

Johnson & Johnson (J&J) and Janssen continue developing their COVID-19 vaccine candidate per ethical standards and sound scientific principles. The J&J vaccine can remain stable for an estimated timeframe of two years at -20°C (-4°F) and can be refrigerated for up to three months at 36–46°F (2–8°C).

The WHO interim recommendations on the use of the Janssen Ad26.COV2.S (COVID-19) vaccines were developed based on advice issued by the Strategic Advisory Group of Experts on Immunization. This document was updated: Version June 15, 2021.

The Janssen COVID-19 (Ad26.COV2.S) vaccine's Accession Number: DB15857; Unique Ingredient Identifier (UII): JT2NS6183B.  Anatomical therapeutic chemical code J07BX03.

The U.S. FDA published on April 27, 2021, Janssen COVID-19 Vaccine revised Frequently Asked Questions. The FDA published an update on Johnson & Johnson’s Janssen COVID-19 Vaccine Overview and Safety for Recipients and Caregivers on July 12, 2021.

COVID-19 Vaccine Janssen (Johnson & Johnson) History

On February 27, 2021, the U.S. Food and Drug Administration (FDA) issued an emergency use authorization (EAU) enabling the Janssen COVID-19 Vaccine to be distributed in the U.S for use in individuals 18 years of age and older. An amended (EAU) was issued on April 23, 2021.

J&J announced on March 12, 2021, that the World Health Organization had issued Emergency Use Listing for its single-shot COVID-19 vaccine, developed by the Janssen Pharmaceutical Companies of Johnson & Johnson, to prevent COVID-19 in individuals 18 years of age and older. On April 23, 2021, J&J confirmed Janssen vaccine shipments in the USA would resume after an eleven-day 'pause.'

Furthermore, on March 11, 2021, Johnson & Johnson announced that the Committee for Medicinal Products for Human Use of the European Medicines Agency issued a Positive Opinion to recommend the Conditional Marketing Authorization for its single-dose COVID-19 vaccine candidate, developed by the Janssen Pharmaceutical Companies of J&J, to prevent COVID-19 in individuals 18 years of age and older.

On June 1, 2021, the U.S. CDC published an update to 'J&J’s Janssen COVID-19 Vaccine Overview and Safety, which stated 'women younger than 50 years old should especially be aware of the rare risk of blood clots with low platelets after vaccination.'

COVID-19 Vaccine Janssen (Johnson & Johnson) Indication

Janssen's COVID-19 vaccine is indicated to prevent infection from SARS-CoV-2 coronavirus, which leads to COVID-19 disease in humans. SARS-CoV-2 belongs to a group of viruses called coronaviruses that attack the respiratory system. The U.S. FDA said on May 14, 2021, do not administer the Janssen COVID-19 Vaccine to individuals with a known history of a severe allergic reaction (e.g., anaphylaxis) to any component of the Janssen COVID-19 Vaccine (see Full EUA Prescribing Information).

COVID-19 Vaccine Janssen (Johnson & Johnson) Variants of Concern

A single dose of the J&J COVID-19 vaccine Janssen generated neutralizing antibodies against a range of SARS-CoV-2 variants of concern, which increased over time (the average neutralizing titer at eight months exceeded that average at 29 days), including against the increasingly prevalent and more transmissible Delta (B.1.617.2) variant, the partially neutralization-resistant Beta (B.1.351), the Gamma (P.1) variants and others, including the Alpha (B.1.1.7), Epsilon (B.1.429), Kappa (B.1.617.1) and D614G variants, as well as the original SARS-CoV-2 strain (WA1/2020).

“Current data for the eight months studied so far show that the single-shot Johnson & Johnson COVID-19 vaccine generates a strong neutralizing antibody response that does not wane; rather, we observe an improvement over time. In addition, we observe a persistent and particularly robust, durable cellular immune response,” said Mathai Mammen, M.D., Ph.D., Global Head, Janssen Research & Development, J&J.

COVID-19 Vaccine Janssen Adolescent (Johnson & Johnson) Indication

On April 2, 2021, J&J confirmed vaccinating adolescent participants in the ongoing Phase 2a clinical trial. The randomized, double-blind, placebo-controlled Phase 2a study (VAC31518COV2001) has been ongoing since September 2020. The study now includes adolescents 12 to 17 years of age.

COVID-19 Vaccine Janssen (Johnson & Johnson) Dosage

J&J vaccine Ad26COVS1 (JNJ-78436735) is administered IM as a single vaccination. The phase 3 ENSEMBLE study evaluates the safety and efficacy of a single vaccine dose of Janssen COVID-19.

COVID-19 Vaccine Janssen (Johnson & Johnson) Ingredients 

The Janssen COVID-19 Vaccine includes the following ingredients: recombinant, replication-incompetent adenovirus type 26 expressing the SARS-CoV-2 spike protein, citric acid monohydrate, trisodium citrate dihydrate, ethanol, 2-hydroxypropyl-β-cyclodextrin (HBCD), polysorbate-80, sodium chloride.

COVID-19 Vaccine Janssen (Johnson & Johnson) Side Effects

The U.S. CDC published Possible Side Effects of COVID-19 vaccines on March 5, 2021. Adverse reactions reported in a clinical trial following the Janssen COVID-19 Vaccine administration include injection site pain, headache, fatigue, myalgia, nausea, fever, injection site erythema, and injection site swelling. In addition, in clinical studies, severe allergic reactions, including anaphylaxis, have been reported following the administration of the Janssen COVID-19 Vaccine.

On April 20, 2021, the EMA’s safety committee concluded that a warning about unusual, very rare blood clots with low blood platelets should be added to the product information for COVID-19 Vaccine Janssen.

On May 11, 2021, the CDC stated, 'women younger than 50 years old especially should be aware of the rare risk of blood clots with low platelets after vaccination, and that other COVID-19 vaccines are available where this risk has not been seen.'

The WHO published updated findings on May 19, 2021, which concluded by saying, 'Based on a careful scientific review of the available information, the subcommittee came to the following conclusions and recommendations the benefits of the J&J COVID-19 vaccine continue to outweigh the risks of thrombocytopenia syndrome.'

On May 26, 2021, the EU country of Belgium suspended Johnson & Johnson's Janssen COVID-19 vaccinations for people under the age of 41 following the first death in Europe from severe side-effects associated with the shot, reported Reuters.

On June 7, 2021, the EMA’s COVID-19 task force (COVID-ETF) began advising healthcare professionals in the EU to consider recommendations by learned societies when assessing people with signs and symptoms of thrombosis with thrombocytopenia syndrome (TTS) following vaccination with Janssen COVID-19. TTS requires rapid identification and urgent clinical management. National and international recommendations have been updated with evolving experience from managing TTS and heparin-induced thrombocytopenia and thrombosis, a condition with some similarities to TTS.

The EMA’s safety committee recommended that people who have previously had capillary leak syndrome must not be vaccinated with COVID-19 Vaccine Janssen on July 9, 2021. The Committee also recommended that capillary leak syndrome should be added to the product information as a new side effect of the vaccine.

On July 12, 2021, U.S. FDA issued a Letter to Janssen stating, 'This letter is to notify you that we have reviewed your requested changes and data to support revisions to your Authorized EUA Fact Sheets, as well as FDA-required changes to include new information about Guillain-Barré syndrome and that your request is granted.'

The EMA published an update on the safety of COVID-19 Vaccine Janssen on July 14, 2021. This document outlines the outcomes from the assessment of emerging worldwide safety data carried out by EMA’s Pharmacovigilance Risk Assessment Committee (PRAC). It also contains high-level information from the reporting of suspected adverse reactions, which PRAC takes into account in its assessments (see section 2). As of July 4, 2021, a total of 12,036 cases of suspected side effects with COVID-19 Vaccine Janssen were spontaneously reported to EudraVigilance from EU/EEA countries; 68 of these reported a fatal outcome. Around that time, about 8.5 million doses of COVID-19 Vaccine Janssen had been given to people in the EU/EEA.

They reached 100% by day 57 with a further increase in titers (GMT, 288 to 488) in cohort 1a. After that, titers remained stable until at least day 71. A second dose provided an increase in the titer by a factor of 2.6 to 2.9 (GMT, 827 to 1266). Spike-binding antibody responses were similar to neutralizing-antibody responses. On day 14, CD4+ T-cell responses were detected in 76 to 83% of the participants in cohort 1 and 60 to 67% of those in cohort 3, with an apparent skewing toward type 1 helper T cells. CD8+ T-cell responses were robust overall but lower in cohort 3.
