The US Food and Drug Administration (FDA) has proposed simplifying the COVID-19 vaccination schedule and that the doses be annual, as is the case with the common flu.
In a series of documents published this Monday on its website, the US regulator indicated that most people may only need a yearly dose to protect themselves from disease, regardless of previous doses.
FDA noted that the Young people who have not been exposed to COVID, the elderly or the immunocompromised may need two annual doses.
The idea of this organization would be to evaluate the possible new variants of the virus that are circulating throughout the year and pick one that you think will be prevalent in the fall to develop the vaccine, as is often done with the flu.
The US regulator indicated that it is possible that most of the population only needs an annual dose to protect themselves from the disease.
In its documents, the agency advocates creating a single composition for the vaccine, instead of what has been the case up to now, with a combination of monovalent sera (those used in the original COVID vaccines and in the first reinforcement) and other polyvalent ones (those of the reinforcement against Ómicron).
“Simplifying vaccine composition should reduce complexity, decrease vaccine administration errors due to the complexity of different vial presentations, and potentially increase vaccination compliance by allowing clearer communication,” details the FDA in its writings.
The FDA's Advisory Committee on Vaccines and Biologicals, an independent body made up of scientists, is expected to evaluate the future of the vaccine on Thursday lel COVID in the US and vote whether or not you support the recommendations of the regulator.
Reduction of reinfections
Far from appeasing, after 3 years since its appearance in China and a high dispersion throughout the world, infections by SARS-CoV-2 do not stop and continue to increase in different waves< /b>. It is that the appearance of new sublineages drives increases in COVID-19 cases in areas that had returned to “normality”.

This increase in infections also occurs in vaccinated people and those previously infected months or years ago, although to a lesser extent, such as for example, he points to a recent scientific study.
Research published in Nature Medicinefound that recent vaccinations and applied boosters reduce infectivity, although the risk of contagion is still high. Researchers proved that vaccination and boosting, especially when recent, help limit the spread of COVID-19 in California prisons during the first wave of Omicron, according to an analysis by researchers at University of California, San Francisco that examined transmission between people living in the same cell.
Study demonstratesbenefits of vaccination and booster, even in settings where many people are still infected, to reduce transmission. And it shows the cumulative effects of the booster and the added protection that vaccination provides to those who were previously infected. The probability of transmission was reduced by 11 percent for each additional dose.
