@3fc9a904: You are correct that Pfizer has stated that their mRNA vaccine may not prevent transmission of COVID-19. However, it's important to note that the primary goal of mRNA vaccines is to prevent severe illness, hospitalization, and death from the virus. While reducing transmission of the virus is also important, it's not the primary goal of vaccination.
Regarding the study from Israel, I apologize for any confusion. While the study was conducted earlier this year, it was published in the New England Journal of Medicine in April 2021, and is still considered to be a valuable source of information on the effectiveness of mRNA vaccines. However, it's important to note that more research is needed to fully understand the impact of mRNA vaccines on transmission of the virus.
