Janssen/J&J COVID-19 vaccine
The Johnson & Johnson’s Janssen (J&J) SARS-CoV-2 viral vector vaccine is the third COVID-19 vaccine that received emergency use authorization (EUA) by the FDA.
J&J has also received an EUA for administration of a single COVID-19 vaccine booster dose for individuals 18 years of age and older, two months after completion of the J&J primary series, five months after completion of the Pfizer-BioNTech primary series or six months after completion of the Moderna primary series.
However, mRNA COVID-19 vaccines are preferred for the primary series and booster dose, over the J&J COVID-19 vaccine for the prevention of COVID-19 for those 18 years of age and older due to the risk of rare adverse events such as thrombosis with thrombocytopenia (TTS).
Currently authorized or approved mRNA COVID-19 vaccines are Pfizer-BioNTech’s and Moderna’s mRNA vaccines.
