Following Pfizerâs announcement that a booster shot for the COVID-19 vaccine could be in the future, some may be wondering why it is needed.
âThereâs nothing definite yet about having a booster for the Pfizer or Moderna, but itâs likely that theyâll be some type of annual vaccination,â Said Dr. Steven Berk, an Infectious Disease physician and dean of the Texas Tech Health Sciences Center School of Medicine.
Some people have been vaccinated now for six months, what is unknown is whether the antibodies are still around, Berk said. There is not enough data yet to know for sure whether a booster shot will be needed for the COVID-19 vaccine, but Pfizer and Moderna are anticipating the need for the booster.
