There is still no scientific support for the application of a third dose of the vaccine

However, they urged Americans 12 and older who have not yet been vaccinated to get vaccinated.

“People who are not vaccinated remain at risk. Virtually all hospitalizations and deaths from Covid-19 are unvaccinated people,” the statement said.

The virus has so far killed more than four million people worldwide during this year and a half of the pandemic.

The United States leads with the most reported deaths, with more than 600,000, followed by Brazil and India.

The statement came shortly after Pfizer and BioNTech announced their intention to seek authorization for a third dose of their coronavirus vaccine, stating that lab tests show people’s immunity begins to wane after the first doses.

For the moment “it is too early to confirm if and when a booster dose will be necessary for the Covid-19 vaccines, because there is still not enough data from the vaccination campaigns”, indicated today sources from the European Medicines Agency (EMA) before. a consultation and stressed that “studies are still underway to understand how long the protection of the vaccine will last.”

However, they clarified that “the EMA will review the data as soon as it becomes available” to ensure swift procedures for authorization “as soon as possible if necessary”.

From the data currently available, “it appears that the four vaccines authorized in the EU protect against all strains circulating in the EU, including the Delta variant,” they added.

“This highlights the importance of a complete vaccination cycle,” they developed.

For the WHO, too, it is not clear whether a third booster dose is useful in maintaining protection against the virus and the evidence for its usefulness is “limited”.

“We do not know if booster vaccines will be needed to maintain protection against the coronavirus until more data is collected,” the WHO said in a statement.

It is not yet studied on the current doses, and neither if an additional booster dose is beneficial and for whom, supplemented the WHO.
