Vaccinations seem to be occurring fastest in Israel now.
“We do know that vaccines are decreasing the incidence of severe disease. That’s it,” he told AFP. “We do not know whether the vaccines are minimizing transmission.”
There is a question about if a vaccinated person can still spread the virus while they don't get sick.

I actually read a Dr on social media talk about Fauci discussing this earlier:
Q: How soon will we have enough evidence to know if mRNA vaccines protect recipient from asymptomatic infection or the ability to infect others?
A: Follow-up data are being collected from vaccine trial volunteers now. If there are significantly fewer asymptomatic infections & a lower level of virus in the noses of vaccine recipients, it would suggest a decreased ability to transmit the virus following vaccination.
