The European Union (EU) drug regulator warned yesterday that frequent booster vaccinations with the new coronavirus vaccine might adversely affect the immune system.
The European Medicines Agency (EMA) points out that repeated booster vaccinations every four months may eventually reduce immunity. Countries said they should take more time between booster vaccinations and keep up with the arrival of the cold season, as shown in the blueprint for influenza vaccination strategies.

With the rapid spread of Omicron infections, some countries are considering the possibility of a second booster vaccination. This month, Israel has started a fourth vaccination (second booster) for people over the age of 60. The UK does not need a second booster at this time, but will review the data as needed.
Regarding booster vaccination, Marco Cavaleri, who is in charge of vaccine strategy at EMA, said, “I don’t think it should be repeated many times, once or twice.” “We need to think regarding how we can move from the current pandemic situation to a more endemic situation,” he said at a press conference.
