ARCHIVED - Europe concerned about countries overusing Covid boosters
The EMA is worried that too many jabs will ‘saturate’ the immune system and render them ineffective
The European Medicines Agency (EMA) has observed with concern the plan of many nations to administer a booster dose of the coronavirus vaccine on a regular basis, warning that too many jabs could lead to “oversaturating the immune system with repeated vaccinations.”
While the head of Strategy for Biological Health Threats and Vaccines, Marco Cavalieri, has argued that it is still far too early to begin treating Covid like the seasonal flu, he believes that booster vaccines should follow a trend similar to influenza, whereby people are immunised annually.
"It is moving towards an epidemic, although it has not yet reached this status. With the Omicron there will be more natural immunity, in addition to vaccination, so that it will advance more quickly towards an epidemic scenario," Cavalieri predicted at a press conference on Tuesday January 11.
The expert has acknowledged that a third vaccine is absolutely necessary given the current stage of the health crisis, but insists that more research is needed before a firm decision can be made on a fourth booster, something which WHO has already heavily criticised.
In any case, the EMA is pleased with the efficacy of the current vaccines against Omicron in particular. Recent data from the UK shows that, although protection decreases a few months after vaccination, it increases again to 90% after the booster is administered.
The entire discussion may be made moot by scientists in Japan who claim to have developed a coronavirus vaccine that only needs to be taken once in a lifetime. Clinical trials on the Kohara jab aren’t due to begin until early 2023, but Tokyo-based pharmaceutical company Nobelpharma Co. is already calling it a “dream” drug that provides permanent protection against Covid.
The revolutionary drug, which is based on the vaccine that was created against smallpox, claims to outperform both the Pfizer and Moderna vaccines, doesn’t require a booster shot and can be stored dry at room temperature, which would be a huge advantage for countries with tropical climates.
