Covid vaccine: Moderna working on booster shots for South African strain

Moderna said Monday it’s accelerating work on a Covid-19 booster shot to guard against the recently discovered variant in South Africa.

Paul Offit, director of the Vaccine Education Center at Children’s Hospital of Philadelphia, said he’s glad Moderna is preparing for the possibility that the virus could mutate enough to evade the protection of the current vaccines.

On Thursday, White House health advisor Dr. Anthony Fauci said new data showed that the Covid-19 vaccines currently on the market may not be as effective in guarding against new, more contagious strains of the coronavirus.
