Towards an annual Covid reminder campaign in the United States – Sciences et Avenir

Barring the virus evolving too quickly, U.S. health authorities said on Tuesday that they wish to run only one Covid reminder campaign per year in the future, modeled on flu vaccinations.

Last week, the United States authorized a new version of the Covid-19 vaccine from Pfizer and Moderna that targets the Omicron variant, more specifically the BA.4 and BA.5 lines currently in circulation in the country.

Doses have already begun to be distributed, so the massive recall campaign planned by the government to contain a possible new wave this winter could start as early as this week.

Unless a “very different” option suddenly emerges, “we will likely move towards a vaccination frequency similar to the annual flu shot, with updated Covid booster doses to stick with the latest circulating strain,” the press release said. conference Dr. Anthony Fauci, White House Counsel.

This view could have contributed to wider acceptance of boosters, with only half of eligible people taking their first booster dose in the United States.

However, weakened populations, such as the elderly or immunocompromised, may need more frequent boosters, Fauci said.

Americans are encouraged to get their flu shots at the same time.

“I really think that’s why God gave us two hands, one for the flu vaccine and one for the Covid vaccine,” said Ashish Jha, who is coordinating the US executive branch’s response to the coronavirus.

“We expect millions of people to get injections this month,” he added.

More than 90% of Americans will live within 5 miles of a vaccination site by the end of the week, according to Health Secretary Xavier Becerra.

The Omicron recall by Pfizer is permitted for persons over 12 years of age, while Moderna is permitted for persons over 18 years of age. This must be done at least two months after the previous dose.

Variants BA.4 and BA.5 currently account for more than 99% of the approximately 80,000 new daily infections in the US.

Nearly 100,000 hospitalizations and 9,000 deaths are predicted to have been avoided if reminders against Covid were held in the same proportion as against influenza this fall, said Rochelle, director of the Centers for Disease Prevention and Control (CDC). Valensky.
