COVID-19 mRNA vaccine update 12

This video update on mRNA vaccines discusses: a recent preprint comparing natural SARS-CoV-2 infections prior to vaccination vs mRNA vaccination for protection against infection with Delta; what natural infection might mean for the future of the pandemic; and finally the recent FDA approval of Pfizer/BioNTech vaccine with an interesting finding about the clinical studies controls.
NB** Sorry for the mistake at 7min 45s of saying, “increasing number” instead of saying, “increasingly limited number of unvaccinated”.
