A Covid-19 vaccine does not provide full or immediate protection, which means it's still possible to get infected and test positive for the virus. Democratic Rep. Stephen Lynch of Massachusetts did.
He tested positive after he got his second dose of the Pfizer vaccine. Hall of Fame basketball coach Rick Pitino, who coaches the men's team at Iona College in New York, also tested positive after getting his first dose.
They could have tested positive for a few reasons.
There's a lag between vaccination and protection It takes a few days to a few weeks for the vaccine to work, according to the US Centers for Disease Control and Prevention. You could test positive before the vaccine kicked in.
"It takes a while for the immune response to develop." said Dr. Robert Salata, director of University Hospitals Roe Green Center for Travel Medicine & Global Health in Cleveland.
The first dose may provide some protection, but as the Moderna CEO, Stephane Bancel said Monday "but we really just don't have any data to prove that at this point."
For Pfizer, after 14 days the first dose was around 52% effective at preventing disease, Salata, who was the lead investigator for the Pfizer vaccine at his hospital, said.
Vaccination prevents most, but not all disease You could still test positive after being vaccinated since the vaccine is not 100% effective. The two US-authorized vaccines are highly effective but they don't provide total protection. The Pfizer vaccine was 95% effective at preventing illness in clinical trials after people got two doses.
The Moderna vaccine was 94% effective at preventing illness in people who got two doses in clinical trials.
