The US Department of Health and Human Services said Monday after a meeting with Pfizer officials that Americans who have been fully vaccinated against COVID-19 do not need a booster dose.
Pfizer announced last week that it plans to ask US regulators To approve a booster dose of the COVID-19 vaccine, based on evidence of an increased risk of infection six months after vaccination and spread of the highly infectious delta variant.
And the giant pharmaceutical company pointed to data from Israel, which is proof of the disappearance of antibodies in vaccinated people – especially the elderly – 6-12 months after the second dose.
Pfizer and the US government feel an urgent need to stay ahead of the virus that causes Covid-19, but we agree Scientific data will determine the next steps in a rigorous regulatory process that we always adhere to Pfizer spokeswoman Sharon Castillo said.
The spread of the delta variant, which was first detected in India and is now the dominant form of infection with the new coronavirus in many countries, has raised concerns of experts around the world about whether available vaccines provide sufficient protection against this strain. Many specialists in the United States believe that a booster vaccine will be foolproof if there is a significant increase in hospitalizations or deaths among vaccinated people.
Representatives of the World Health Organization criticized Pfizer’s concerns on Monday, calling on governments not to order additional doses of vaccines while poor countries are still waiting for supplies to vaccinate their citizens.
The head of the World Health Organization, Somaya Swaminathan, confirmed this The World Health Organization does not have evidence yet that booster vaccinations are necessary for those who have received a full course of vaccinations. She believes that while stimulant doses may someday be necessary, there is no evidence for this yet.
