FDA signs off on updated Covid-19 vaccines that target circulating variants
As for Covid-19, “at the present time, we are seeing an uptick in infection rates as well as hospitalizations, however, the absolute rates of severe disease, hospitalizations, and death are still very low compared with where we were a year ago and two years ago,” said Dr. Dan Barouch, director of the Center for Virology and Vaccine Research at Beth Israel Deaconess Medical Center, who was not involved in developing either the Moderna or Pfizer vaccines but previously helped study the Johnson & Johnson vaccine.
