Pfizer vaccine appears effective against mutation in new coronavirus variants

“The study still does not address a worrisome mutation in the South African variant, called the E484K mutation.”

I&#x27;m so tired of this kind of conjecture.<p>&gt; study by Pfizer and scientists from the University of Texas Medical Branch, which has not yet been peer-reviewed<p>How about we let manufacturers of the vaccines tell us directly whether it&#x27;s effective or not. Or the FDA, CDC, etc.
