The US Food and Drug Administration (FDA, for its acronym in English) proposed to simplify the vaccination schedule against COVID-19 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 it is possible that most of the population only needs an annual dose to protect yourself from disease, regardless of what you have previously received.

The FDA noted that young people who have not been exposed to COVID, the elderly, or those who are immunocompromised may need two doses per year.

The idea of ​​this organism would be to evaluate the possible new variants of the virus that are circulating during the year and choose one that you think will be prevalent in the fall next to develop the vaccine, as is often done with the flu.

In its documents, the agency advocates create a single composition for the vaccineinstead of what it has been up to now, with a combination of monovalent sera (those used in the original COVID vaccines and in the first booster) and other polyvalents (those used in the booster against Omicron).

“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 COVID vaccine in the US on Thursday and vote on whether or not to support the regulator’s recommendations.

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. It is that the appearance of new sublineages drives increases in the cases of COVID-19 in areas that had returned to “normality”.

This increase in infections also occurs in vaccinated persons and those previously infected months or years ago, although to a lesser extent, as indicated by a recent scientific study.

A research published in nature medicine found that recent vaccinations and applied boosters reduce infectivity, although the risk of contagion is still high. The 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 the University of California, San Francisco that examined transmission between people living in the same cell.

The study shows the benefits 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.
