The scientists said that the vaccines would never be able to block all infection.
Early on, the claim was “Everyone get vaccinated, COVID goes away”.
"COVID-19 vaccines are effective at preventing infection, serious illness, and death. Most people who get COVID-19 are unvaccinated. However, since vaccines are not 100% effective at preventing infection, some people who are fully vaccinated will still get COVID-19. This is called a breakthrough infection. Even when people who are fully vaccinated develop symptoms of COVID-19, they tend to be less severe than in people who are unvaccinated."
I was going by that statement and remember it being said the spring of 2020 after I got vaccinated. I wanted to know if my vaccination would protect me from spreading the virus and allow me to wear a mask. I was disappointed but accepted the science.
