“You cannot vaccinate the planet every 6 months. It’s not sustainable, ”says UK’s chief immunization officer.

Andrew Pollard, researcher and director of the Oxford Vaccine Center, and who supported the design of the AstraZeneca inoculation, recently announced that he does not consider a fourth dose of the vaccine to be feasible. coronavirus covid-19, at least so far.

In addition, it qualifies it as something unsustainable.

According to what was mentioned by the also president of the UK Joint Committee on Vaccination and Immunization (JCVI) to the British medium The Telegraph, “we cannot vaccinate the planet every four or six months. It is not sustainable or accessible. In the future, we must target risk groups”.

Although a large part of the nations are taking the respective measures to mitigate the contagion and promote vaccination, it is still necessary to discriminate and catalog what types of populations are the most vulnerable to the virus in order to focus on them, something that Pollard considered fundamental.

• World record: the United States registers more than a million cases of coronavirus in 24 hours
• United Kingdom exceeds 200,000 coronavirus infections in one day for the first time in the entire pandemic
• WHO warns that increased omicron cases could create more dangerous variants of coronavirus

The expert shows optimistic facing the current situation of the virus, so he believes that the worst of the pandemic it has already passed and that the greatest risk is in those who have not been vaccinated.

“The worst is absolutely behind”He told the aforementioned newspaper.

Although it is true that a booster vaccine generates strong antibodies, starting the process and having a three-dose schedule is sufficient for the moment, since it has not been much more scientifically deepened with respect to a fourth vaccine.

Now the important thing, according to Pollard, is to focus on people vulnerable to the virus, since it is known that not all individuals respond the same to the disease and further research is still needed regarding how often a reinforcement is necessary according to the antibodies of the human body.

“People have strong antibodies for a few months after their third injection.”, he pointed out regarding the 3 immunization doses: “More data is needed to assess when and how often risk groups will need additional doses ”.

While the feasibility of a fourth booster is analyzed in greater depth, experts hope that governments will continue to advance with the first and second doses, as it is essential to ensure that a large part of the population begins immunization since the “Higher risk are unvaccinated people”.
