In 2021 was the year that mRNA vaccines started to be administered. So they couldn’t possible know if it stop transmission.
Pfizer also stated that mRNA vaccines don’t stop transmission. That study “Israel” one is not valid.
Discussion
@3fc9a904: You are correct that mRNA vaccines were only authorized for emergency use in late 2020, and more research is needed to fully understand their impact on transmission of the virus. While Pfizer has stated that their mRNA vaccine may not prevent transmission of COVID-19, there is still some evidence to suggest that mRNA vaccines may reduce transmission of the virus. For example, a study from the United Kingdom found that the Pfizer-BioNTech vaccine was 67% effective in preventing transmission of the virus: https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(21)00628-0/fulltext.
Regarding the study from Israel, while it is true that more research is needed to fully understand the impact of mRNA vaccines on transmission of the virus, the study was conducted using real-world data and has been peer-reviewed and published in a reputable medical journal. However, it's important to continue monitoring the safety and efficacy of mRNA vaccines as more data becomes available.
That Lancet study it’s from march of 2021.
mRNA vaccines started to be administered in early 2021. They had absolutely no data to conclude that. Exactly like the Israel study.
mRNA vaccines don’t stop transmission.
@3fc9a904: You are correct that the Lancet study was published in March 2021, which was after the mRNA vaccines were authorized for emergency use. While the study was conducted using real-world data, it's important to note that more research is needed to fully understand the impact of mRNA vaccines on transmission of the virus.
Regarding the transmission of COVID-19, while mRNA vaccines may not completely prevent transmission of the virus, they have been shown to be highly effective in preventing severe illness, hospitalization, and death from the virus. By reducing the number of people who become seriously ill from COVID-19, mRNA vaccines can help reduce the burden on healthcare systems and save lives. Additionally, by reducing the spread of COVID-19 in the population, mRNA vaccines can help slow the spread of the virus and reduce the overall number of cases, which can help protect vulnerable populations who may be at higher risk of severe illness or death from COVID-19.
