THE ANSWER
No, none of the three COVID-19 vaccines in the US contain live coronavirus, so there’s nothing for vaccinated people to “shed.” The virus is only shed from those infected with COVID-19.
WHAT WE FOUND
“Vaccine shedding” is real, but it can only happen if the vaccine was made with a weakened version of the virus.
All three COVID-19 vaccines used in the US do not contain the live virus, so experts say, they can’t shed the virus.
Pfizer's and Moderna's COVID-19 vaccines contain M-RNA, which teaches the immune system to create the spike protein present on the surface of the coronavirus, but these spike proteins are free of any virus. This elicits an immune response, and the body produces antibodies to fight the virus if it’s exposed to it.
