I was reading that Israel is questioning the effectiveness given for the first dose. The news article said "Many people have been infected between the first and second injections of the vaccine,” Ash said, adding that the protective effect appears “lower than [the data] presented by Pfizer.”
Ash is said to be their equivalent of our Fauci. One of my main concerns throughout is if we have too many people walking around with just 1 dose. I was already concerned about that but hearing they may, in at least one country, question the already low (IMO) efficacy of 52% for 1 dose isn't making my concerns any better.
