We’ve been hearing for months about a possible third booster dose of the coronavirus vaccines made by Pfizer and Moderna. They both take it for granted. And this has been made known to both the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). Both the EMA and the European Center for Disease Prevention and Control (ECDC) they do not see the “urgency” to start with the third doses. And so he has explained it in a new published document. Then Will there be no souvenir dose?
It should be noted, first, that all these recommendations are made taking into account the information and the situation in which we are right now; in addition to the scientific evidence we have. This is due to, among other things, that we still do not know how long the immunity of coronavirus vaccines lasts. The moment any of these things change – for example, we know that immunity is not for life -; the coronavirus vaccine dose guidelines could also become different.
Coronavirus Vaccines: Extra or Booster Dose?
In principle, both the EMA and the ECDC indicate that a third booster dose is not necessary in the general population. However, they do point to an additional dose may be necessary in immunosuppressed people, as is the case of people who have received organ transplants; but also for elderly people who live in residences. In this way, they differentiate between a booster dose (to strengthen the immune system) and an additional dose of the coronavirus vaccine for certain cases.
The EMA and ECDC differentiate between booster doses for the general population and additional doses for the elderly in nursing homes and immunosuppressed people.
Why do immunosuppressed people need an extra dose? It seems that it has been observed that in these patients the two-dose regimen is not entirely sufficient; Since some studies indicate that they have a low response to the coronavirus, according to El Mundo. A third dose of the vaccine could be the missing boost for your immune system to fight this coronavirus.
Although for the moment the EU calls for calm with possible third doses of coronavirus vaccines; Moderna asked last week for approval for her souvenir dose to the EMA. However, the scientific consensus, for the moment, is that there is still a lot to do in the rest of the world in terms of vaccination.
Preventive measures are still necessary
Therefore, ECDC recommends that “to complement vaccination efforts” It’s very important “continue applying measures like physical distancing; hand and respiratory hygiene and use of masks when necessary, particularly in high-risk settings such as long-term care facilities or hospital wards with patients at risk of severe COVID-19. “
Ultimately, for now, the general population should not worry about a third booster dose. However, probably in the next few months yes we hear about an additional dose for certain groups, such as immunosuppressed people or the elderly living in nursing homes.
