Vaccine boosters likely to be needed by next year – immunologist

PfizerBioNTech, currently the most commonly used vaccine in Ireland, has started a trial to see if a third dose could be given as a booster six to 12 months after a first vaccination.

Vaccine boosters are likely to be needed by next year, a Limerick-based immunologist has predicted.

However, Dr Elizabeth Ryan, lecturer at the University of Limerick, said that while the virus may continue mutating, she is confident in vaccines being developed by manufacturers can combat that.
