While the American Food and Drug Administration says it is not certain of long-term effects of the new Pfizer coronavirus vaccine, an Israeli medical official claims he believes “there is no true reasons to think” there would be, The Jerusalem Post has reported.
Tal Brosh, head of the Infectious Disease Unit at Samson Assuta Ashdod University Hospital, says he cannot claim to know what is going to happen in the next 10 years, but has a positive outlook on the effectiveness of the new vaccine and the potential for problems.
Brosh told the Jerusalem Post that “there is no other vaccine that was evaluated for a decade before approval and that there is not an example of another vaccine—although no other vaccine is an mRNA vaccine, that has been linked to any significant long-term effects.”
Michael Linial, a professor of biological chemistry at Hebrew University of Jerusalem, says if the reaction to the vaccine wasn’t immediate, most likely it wouldn’t happen at all.
“There is no evidence of something happening unless it happened in the first two hours, two weeks or two months,” Linial says. “We do not know of any other examples in which the immune system decided to suddenly react that was given 15 years prior.”
The Jerusalem Post reported that more than 2 billion people worldwide have been vaccinated against COVID-19, with more than five billion doses distributed. Approximately 210 million Pfizer mRNA doses have been distributed in America. In Israel, more than 8.5 million doses have been administered.
The Centers for Disease Control and Prevention, The Jerusalem Post reports, says mRNA vaccines “teach our cells how to make protein—or even just a piece of a protein—that triggers an immune response inside our bodies. That immune response, which produces antibodies, is what protects us from getting infected if the real virus enters our bodies.”
But Brosh says that does not mean the vaccine changes people’s genetic code.
