I wouldn't take Biden at his word if he said water is wet.
Very few vaccines prevent people from getting the virus. Some do offer sterilising immunity, but those are relatively few. The COVID vaccines are not reported to produce sterilising immunity, regardless of what President Biden says. We knew this from the start.
My complaint is there are people who are confused about the vaccine. Some believe vaccines always provide sterilising immunity. Others believe vaccines that do not are not vaccines or are ineffective vaccines. Both of these groups are ignorant and confused.
The COVID vaccine, the Chickenpox vaccine, the measles vaccine....none of these provide sterilising immunity (always that is always the goal).
I do not care who gets vaccinated and who does not. But all this misinformation (on both sides) is juvenile.
The way it looks, it may very well be primarily vaccinated people around to see the juliet versions.
