Janssen COVID-19 Vaccine

The Janssen COVID-19 vaccine (Ad26.COV2.S) is a recombinant vaccine that contains an adenovirus serotype 26 (Ad26) vector expressing a stabilized SARS-CoV-2 spike protein. The vaccine was created in collaboration with Johnson and Johnson (J&J), Janssen Pharmaceutical, and the Beth Israel Deaconess Medical Center. A preclinical study in hamsters infected with SARS-COV-2 infection showed a single immunization with the vaccine-elicited neutralizing responses and protected against SARS-CoV-2 induced pneumonia and mortality, providing protection against the disease progression. Follow-up preclinical studies in rhesus monkeys showed that the Ad26 vaccine produced a robust response and provided near perfect protection in nasal swabs and bronchoalveolar lavage following SARS-COV-2 challenge. As of June 2020, a Phase 1/2 clinical trial in adult humans was announced to evaluate the safety, immunogenicity, and efficacy of the ad26.COV.S vaccine in 1045 healthy adults between the ages of 18-55 (NCT04436276). The Janssen COVID-19 vaccine is available under an Emergency Use Authorization (EUA) in the US.

Janssen COVID-19 Vaccine is indicated for active immunization for the prevention of coronavirus disease-2019 (COVID-19) caused by SARS-CoV-2 virus in individuals 18 years of age and older. In the US, Janssen COVID-19 vaccine is authorized for use under an Emergency Use Authorization (EUA) for active immunization to prevent COVID-19 caused by SARS-CoV-2 in individuals 18 years of age and older for whom other FDA-authorized or approved COVID-19 vaccines are not accessible or clinically appropriate, and in individuals 18 years of age and older who elect to receive the Janssen COVID19 Vaccine because they would otherwise not receive a COVID-19 vaccine.
