"A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease"
im·mu·ni·ty: the ability of an organism to
resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells.
CNBC:
It’s difficult to know the full extent of “breakthrough” Covid cases because cases in vaccinated people tend to be mild or asymptomatic and could go easily go unnoticed, but figures collected by NBC News has found that at least 125,000 fully vaccinated Americans have tested positive for Covid and 1,400 of those have died.
It does not stop the spread of Covid!! You are not immunized against Covid taking the experimental gene therapy.
