We wanted the best, but it turned out as always: it turned out that booster vaccinations against COVID-19 harm the immune system

European Union regulators have warned that frequent booster shots against Covid-19 can negatively affect the immune response and may not be helpful. Bloomberg.

According to European Medicines AgencyRepetitive booster doses every four months can eventually weaken the immune response and tire the person's immune system. Instead, countries should allow more time between booster programs and tie them to the start of the cold season in each hemisphere. The plan outlined in the influenza vaccination strategies must be followed, the agency said.

Some countries are considering offering people booster shots to provide additional protection against the surge Omicron... Earlier this month, Israel became the first country to begin giving a second or fourth booster shot to people over 60. The UK said boosters provide a good level of protection. Currently not necessary in the second booster, but the data may be revised as they develop.

Boosters “can be done once or maybe twice, but we don't think it should be repeated all the time,” Marco Cavaleri, EMA's head of biological health threats and vaccine strategy, said in a January 11 press briefing. "We need to think about how we can move from the current pandemic environment to a more endemic one."

The EU regulator also said in a briefing that oral and intravenous antiviral drugs such as paxlawid and remdesivir remain effective against Omicron. The agency said April is the earliest time it can approve a new vaccine targeting a specific option, as the process takes three to four months. Some of the world's largest vaccine manufacturers have said they are considering producing vaccines that could target new options.
