European Medicines Regulator Argues Against Repeated COVID-19 Boosters – Here’s Why!

While we are all still dealing with a new wave of COVID and the emergence of a new, much more easily transmissible variant, Omicron, vaccination as well as the booster shot remain the most effective defenses against getting really ill.

At the same time, however, there have also been discussions about having to get the booster shot not just once but every few months to a year in order to keep ourselves protected from COVID-19 until the virus is finally under control.

That being said, it turns out that might not be a good idea after all!

According to the European Medicines Agency’s (EMA) head of biological health threats and vaccines strategy, Marco Cavaleri, repeat booster dosing might come with some unintended consequences, namely weakening one’s immune response, which is the exact opposite of what we should thrive for in the fight against COVID.

Bloomberg reports that Cavaleri stated during a news conference that boosters are effective as long as they are done once or twice, going on to explain that “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.”

His statement comes just as many countries out there have been upping their vaccine orders, anticipating that there may be a need for yet another booster dose in about 6 months or so as the protection of the vaccine slowly wanes over time.

And that is not all! Cavaleri’s words also come not too long after the current president of the United States suggested there may, indeed, be a need for additional vaccinations.

More precisely, a newspaper report from last week indicated that Joe Biden and his administration are getting ready to ask Congress for some extra funding for COVID prevention.
