Moderna is only valid for adults over 18 years of age.
“Current evidence points to some reduction in protection against the serious effects of Covid-19 in the elderly and immunocompromised individuals,” said Peter Marks, director of the FDA’s Center for Biological Assessment and Research. In the statement. “Based on the analysis of the developed data, a second boost dose of Pfizer-BioNTech or Moderna Covid-19 vaccine may help to increase the level of protection of these high-risk individuals.
Wallpaper: The move comes as the Biden administration and public health experts worry about a potential new increase in cases. Across Europe, the highly infectious BA.2 variant is spreading rapidly and many fear it will soon lead to a live increase in cases in the US of BA.2, a sub-variant of Omicron, which accounts for more than 54 per cent of cases nationwide, accounting for 39 per cent.

“By choosing to be over the age of 50, which we often use for other respiratory viruses, such as the flu, to target people at higher risk, we thought we would restrain the population that would benefit most from this fourth booster dose,” Marx said. Press service with journalists.
The United States has enough booster doses for these populations, said Don O’Connell, secretary of the Department of Health and Human Services for Preparedness and Response, at a news conference Monday. “What worries us is … if another option comes out and we need to strengthen a specific option in a few months. “It will be quite expensive and we do not have these doses on hand and we do not currently have the funding to cover these doses,” he added.

“People may need to get extra boosters in the fall with a more general boost campaign,” he said.
He said the strategy will be discussed at the next meeting of the Vaccine Advisory Committee, which The meeting is scheduled for April 6. In addition to reviewing Covid-19 amplifiers, the committee reviews best practices for companies seeking to design strikes against future strains of the virus.
