Some good news from Pfizer today: In tests, their COVID vaccine has shown to be  ‘100% effective against South African variant, beats Brazilian strain’ AND works for at least six months.

Dr. Anthony Fauci called the results ‘really very encouraging.’

The trial data ‘provide the first clinical results that a vaccine can effectively protect against currently circulating variants, a critical factor to reach herd immunity and end this pandemic for the global population,’ Ugur Sahin, chief executive officer at BioNTech, said in a statement.

Since the COVID vaccine is so new, no one knows how long the COVID antibodies last so the jury is still out on whether we’ll all need a booster shot at some point in the fall.
