Jcovden® COVID-19 Vaccine 2023

The Jcovden® COVID-19 Vaccine (Ad26.COV2.S) is a recombinant, replication-incompetent adenovirus serotype 26 (Ad26) vector encoding a full-length and stabilized the SARS-CoV-2 spike protein. This Janssen-produced U.S. Food and Drug Administration (FDA)-authorized COVID-19 vaccine does not contain adjuvants, preservatives, materials of animal origin, or fetal tissue.

The viral vector used in the Jcovden Janssen - Johnson & Johnson (J&J) COVID‑19 Vaccine is based on a naturally occurring, low-prevalence human adenovirus known to cause common cold-like symptoms. Deleting a specific gene renders the adenovirus unable to replicate within humans, transforming it into a delivery vehicle for the genetic material encoding the spike protein of the SARS-CoV-2 betacoronavirus. In this form, the vaccine cannot cause COVID‑19 or adenoviral disease.

The Jcovden COVID‑19 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. The AdVac® technology works by using an adenovirus as a vector of an antigen's genetic code to mimic components of a pathogen. The 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. 

Johnson & Johnson announced that the U.S. FDA issued an Emergency Use Authorization (EUA) on February 27, 2021, for its single-dose COVID-19 vaccine, developed by the Janssen Pharmaceutical Companies. On October 20, 2021, the FDA authorized a single booster dose of the Janssen COVID-19 Vaccine, and the FDA authorized a heterologous booster dose for currently available COVID-19 vaccines. On February 11, 2022, the U.S. Centers for Disease Control and Prevention (CDC) issued new guidance for those who received the Jcovden Janssen COVID-19 Vaccine primary series should receive an additional dose and a booster dose for a total of 3 doses to be classified as up to date. And on March 29, 2022, the CDC stated, 'Adult Janssen primary vaccine (2-doses) recipients should preferentially receive a heterologous mRNA vaccine booster dose ≥ two months later.'

The World Health Organization (WHO) Listed the Jcovden COVID-19 vaccine for emergency use in all countries on March 12, 2021. The U.K. granted marketing authorization for the Janssen Covid-19 vaccine on May 28, 2021, and updated it on November 3, 2022. In addition, the European Medicines Agency (EMA) published the latest clinical data EMEA/H/C/005737/II/0033; the EMA overview is found at this link. The authorization or approval status of the Jcovden COVID-19 vaccine varies by country. This country list is updated as additional information becomes available.

Jcovden SARS-CoV-2 Virus Variants

A study published in the peer-reviewed journal Nature on January 31, 2022, shows that the Jcovden vaccine provided robust cellular protection against serious illness caused by the highly transmissible Omicron (B.1.1.529) variant. Previously, Heather Scobie, Ph.D., MPH, resented an Update on Omicron Variant during the ACIP Meeting on December 16, 2021. And the JAMA published a study on November 2, 2021, that found the Janssen COVID-19 vaccine is 74% effective in preventing SARS-CoV-2 infection even amid phases of high Alpha (B117) and Delta (B1617.2) variant circulation.

Jcovden Dosage

The Jcovden vaccine is administered as a single (0.5 mL) vaccination.

Jcovden Boosters

A single booster dose is recommended at least two months after the second (additional) dose, for a total of 3 doses (1 Janssen vaccine dose followed by one additional mRNA vaccine dose, then one booster dose). mRNA vaccines are preferred for the booster dose. If the Moderna vaccine is used for the booster dose, a 50 µg (0.25 ml) dose should be used.

On December 15, 2021, the EMA authorized Jcovden boosters and mixing-and-matching dosing for adults. In addition, on December 5, 2021, J&J announced preliminary results from a non-peer-reviewed independent phase 2 study, including a subset of participants from the Janssen-sponsored COV2008 study, conducted by Dan Barouch, M.D., P.D., et al. of Beth Israel Deaconess Medical Center (BIDMC), which showed that a booster shot of the Johnson & Johnson COVID-19 vaccine (Ad26.COV2.S), administered at six months after a two-dose primary regimen of BNT162b2, increased both antibody and T-cell responses. These results demonstrate the potential benefits of heterologous boosting.

Jcovden Side Effects

The U.S. FDA stated on May 5, 2022, an updated analysis of Thrombosis and Thrombocytopenia Syndrome (TTS) cases following the administration of the Jcovden Vaccine that was reported to VAERS through March 18, 2022, the FDA and CDC have identified 60 confirmed cases, including nine fatal cases. Therefore, the FDA has determined that the reporting rate of TTS is 3.23 per million doses of vaccine administered, and the reporting rate of TTS was 0.48 per million doses of vaccine administered. 

The EMA's medicines safety committee recommended on April 3, 2022, that small vessel vasculitis with cutaneous manifestations (inflammation of blood vessels in the skin, which may result in a rash, pointed or flat, red spots under the skin's surface, and bruising) should be added to the product information of COVID-19 Vaccine Janssen as a possible side effect of unknown frequency. The EMA published its monthly safety update confirming 45,947 suspected side effects, and 308 of these reported a fatal outcome in the EU/EEA. The EMA Fact Sheet was updated.

In addition, the most commonly reported side effects were pain injection site, headache, fatigue, muscle aches, and nausea. Most of these side effects occurred within 1-2 days following vaccination, were mild to moderate, and lasted 1-2 days, stated Janssen's August 2, 2021 update. Anyone with an acute febrile illness (body temperature over 38.5 ºC) should postpone vaccination until they are afebrile. A history of anaphylaxis to any vaccine component is a contraindication to vaccination.

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, EMEA/H/C/005737, developed by the Janssen Pharmaceutical Companies of J&J, to prevent COVID-19 in individuals 18 years of age and older.
