Jcovden® COVID-19 Vaccine (Janssen, Johnson & Johnson) For 2022

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. 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. For example, on January 6, 2022, a study found Ad26.COV2.S showed more durable protection against breakthrough infections and hospitalizations in line with published evidence of its durable antibody and cellular immune response.

Johnson & Johnson (J&J) announced that the U.S. Food and Drug Administration (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 U.S. 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 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 Ad26.COV2.S, developed by Janssen, for emergency use in all countries on March 12, 2021. The WHO's SAGE published a Version #9 updated overview on December 9, 2021. The U.K. granted marketing authorization for the Janssen Covid-19 vaccine on May 28, 2021, and updated it on November 3, 2022. On March 22, 2022, the 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. Unless approved or licensed by the relevant health authority, the product is investigational, and its safety and efficacy have not been established. This country list is updated as additional information becomes available.

On May 5, 2022, the U.S. EUA Fact Sheets and Prescribing Information for Johnson & Johnson's Janssen COVID-19 Vaccine were updated. In addition, the WHO issued interim recommendations for the use of the Janssen Ad26.COV2.S on June 6, 2022.

U.S. FDA Announcement Regarding Jcovden

On May 9, 2022, the FDA limited the authorized use of the Jcovden COVID-19 Vaccine to individuals 18 years of age and older for whom other authorized or approved COVID-19 vaccines are not accessible or clinically appropriate and to individuals 18 years of age and older who elect to receive the Jcovden COVID-19 Vaccine because they would otherwise not receive a COVID-19 vaccine.

Jcovden Omicron, BA.x

As of June 16, 2022, the U.S. NIH OpenData Portal reported Reported in vitro Therapeutic Activity. Given its recent designation, Omicron/B.1.1.529 therapeutic activity data is currently being reported rapidly. On May 5, 2022, the peer-review journal NEJM reported a study based in South Africa that reported after two doses, the Jcovden vaccine was effective against severe diseases caused by the omicron variant. The national vaccine program in South Africa has distributed 8,477,267 doses of the Ad26.COV2.S vaccine. Among the Ad26.COV2.S vaccine recipients, the vaccine effectiveness against ICU admission or high care was 69% (95% CI, 26 to 87) at 14 to 27 days and 82% (95% CI, 57 to 93) at 1 to 2 months after the second dose.

A study published in the peer-reviewed journal Nature on January 31, 2022, shows that the Jcovden Janssen 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. A primary Janssen vaccine dose is recommended for people ages 18 years. On April 7, 2022, the U.S. FDA confirmed information and data to support the extension of the shelf-life of the Janssen COVID-19 Vaccine stored at 2-8oC, from 9 months to 11 months.

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 May 25, 2022, the JAMA published a Correspondence - the results of this study suggest that a single booster dose of an mRNA Covid-19 vaccine in persons who received primary vaccination with single-dose Ad26.COV2.S provided protection close to that of the three-dose mRNA vaccine regimen and supports the current recommendation of a booster dose of mRNA vaccine at least 2 months after primary vaccination with single-dose Ad26.COV2.S or at least 4 months after an Ad26.COV2.S booster dose.

On December 15, 2021, the EMA announced its authorization for Janssen Vaccine boosters and mixing-and-matching dosing for adults. 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., Ph.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.

The VRBPAC issued a report on October 13, 2021, stating, 'The analyses of reactogenicity data during the seven days post-booster and the unsolicited A.E.s within 28 days post-booster do not appear significantly different from those for the single-dose primary vaccination and do not raise new safety concerns. On October 20, 2021, the FDA issued its authorization.

Jcovden Side Effects

The U.S. FDA stated on May 5, 2022, an updated analysis of TTS cases following administration of the Janssen COVID-19 Vaccine that were reported to VAERS through March 18, 2022, the FDA and CDC have identified 60 confirmed cases, including nine fatal cases. 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 deaths is 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.

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 and were mild to moderate in severity 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.

In the U.S., VAERS is a passive reporting system, meaning it relies on individuals to send in reports of their experiences. However, anyone can submit a report to VAERS, including parents and patients.

Jcovden History

On February 27, 2021, the U.S. 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. 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. In addition, J&J announced on March 12, 2021, that the WHO had issued an Emergency Use Listing for its Janssen COVID-19 vaccine. J&J announced on October 15, 2021, that the U.S. FDA Vaccines and Related Biological Products Advisory Committee (ACIP) voted 19-0 to recommend EUA for a booster dose of the Johnson & Johnson Janssen COVID-19 vaccine for adults aged 18 and older at least two months following initial vaccination with the single-shot vaccine. In October 2021, Janssen presented: Booster Dose of Janssen COVID-19 Vaccine (Ad26.COV2.S) Following Primary Vaccination during the ACIP meeting.

Jcovden Children

John R. Su, MD, Ph.D., MPH, presented: Adverse events among children ages 5–11 years after COVID-19 vaccination: updates from v-safe and the Vaccine Adverse Event Reporting System, as of Dec 13, 2021.

Jcovden Women

The WHO recommends the use of Ad26.COV2.S vaccine in pregnancy only if the benefits of vaccination to pregnant women outweigh the potential risks. Pregnancy: Available data on Janssen COVID-19 Vaccine administration to pregnant women are insufficient to inform vaccine-associated risks in pregnancy. Lactation: Data are not available to assess the effects of the Janssen COVID-19 Vaccine on the breastfed infant or milk production/excretion. However, as Ad26.COV2.S is not a live virus vaccine; it is biologically and clinically unlikely to pose a risk to the breastfeeding child. Based on these considerations, WHO recommends using this vaccine in breastfeeding women as in non-breastfeeding individuals. WHO does not recommend discontinuing breastfeeding because of vaccination.

Jcovden HIV

Among phase 3 clinical trial participants with well-controlled HIV, there were no reported differences in safety signals. Therefore, HIV-positive persons who are well controlled on highly active antiretroviral therapy and are part of a group recommended for vaccination can be vaccinated. Information and, where possible, counseling about vaccine safety and efficacy profiles in immunocompromised persons should be provided to inform the individual benefit-risk assessment. It is not necessary to test for HIV infection before vaccine administration.

Jcovden Dialysis Patients

Dialysis patients who received an adenovirus vector-based Janssen COVID-19 vaccine (Johnson & Johnson) were found in a study to have similar rates of breakthrough infection, hospitalization, and mortality as dialysis patients who received an mRNA-based vaccine.

Jcovden Coadministration With Influenza Vaccines

The WHO says limited evidence mainly derived from other COVID-19 vaccines, it is acceptable to co-administer Ad26.COV2.S with an inactivated influenza vaccine. Different arms for injection should be used when both vaccines are delivered during the same visit. Continued pharmacovigilance monitoring is recommended. And no co-administration data are available for other live or inactivated vaccines.

Jcovden 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.

A history of anaphylaxis to any vaccine component is a contraindication to vaccination.

Jcovden CPT Code

The American Medical Association offers resources to help identify the appropriate CPT code.

Jcovden Distribution
