The World Health Organization (WHO) announced this today will recommend only one dose of one of the vaccines to protect against Covid-19, after nearly three years of a global immunization campaign, even for those initially designed for double doses, such as those from Moderna or Pfizer.

“A single dose is sufficient for primary immunization as many people have previously had at least one infection” (of Covid), WHO Director-General Tedros Adhanom Ghebreyesus said at a press conference as he announced this change in strategy. .

The decision was taken after the meeting of the group of immunization experts that advises the organization, chaired by Finland’s Hanna Nohynek, who stressed that this “simplification” in the strategy “will improve the acceptance of the vaccine.”

The expert also indicated that vaccines are based on the ommicron.

“They all remain effective in preventing severe forms of the disease in high-risk groups,” the expert said.

According to data collected from national healthcare networks around the world, About 13,510 million doses of anti-Covid vaccines have been administered on the planet. meaning more than 70% of the world’s population has received at least one dose.

The WHO, which declared the end of an international state of emergency over the disease last May, has recorded at least 770 million cases worldwide, with at least 6.9 million deaths.

The organization itself indicates that these confirmed figures are conservative and that the actual infections and deaths are much higher: in 2021 it already estimated that there had been around 15 million deaths related to the disease, taking into account the excess figures . mortality in every country.
