Frequent revaccinations for coronavirus can negatively affect a person's immune system. According to the European Medicines Agency (EMA), booster doses every four months can weaken the immune system and fatigue people as Bloomberg reported.

The agency recommends instead leaving more time between revaccination programs and tying them to the start of the cold season in each country.

“Boosters can be done once or maybe twice, but it’s not something that we can think should be repeated constantly. We need to think about how we can transition from the current pandemic setting to a more endemic setting,” EMA head of biological health threats and vaccines strategy Marco Cavaleri said.

The EU regulator also said oral and intravenous antiviral drugs such as Paxlovid and Remdesivir remain effective against Omicron. The agency said it won't be able to approve a new vaccine against a particular variant of the coronavirus until April, because the process takes about three to four months. Some of the world's largest vaccine manufacturers have said they are considering producing vaccines that could target new variants.

Earlier, the US Food and Drug Administration (FDA) has amended information about the Johnson & Johnson vaccine. A rare risk of immune thrombocytopenia, particularly bleeding, has been added.
