“This is probably going thanks to both waning immunity, and therefore the strength of the widespread Delta variant,” Murthy said during a public briefing by the White House COVID-19 response team.
The plan, outlined by the director of the Centers for Disease Control and Prevention (CDC) and other top authorities, involves an additional dose eight months after people get their second shot of the Pfizer or Moderna vaccine. The doses could begin the week of September 20.
The announcement comes because the us is experiencing a pointy increase in cases, hospitalisations and deaths, with 13,885 COVID fatalities within the past 28 days, and 623,418 since the pandemic began, consistent with data from Johns Hopkins University.
Health officials said people that received the single-dose Johnson & Johnson vaccine will probably need extra shots. But they’re awaiting more data and have yet to figure out the small print .
The overall plan is awaiting a Food and Drug Administration evaluation of the security and effectiveness of a 3rd dose, the officials said. Officials had already recommended booster jabs for people with weak immune systems.
Health officials said it’s “very clear” that the vaccines’ protection against infection wanes over time, and now, with the highly contagious delta variant spreading rapidly, “we are beginning to see evidence of reduced protection against mild and moderate disease.”
“Based on our latest assessment, the present protection against severe disease, hospitalization and death could diminish within the months ahead,” officials said during a joint statement released by the Department of Health and Human Services.
Officials said the US has an adequate supply of vaccines to supply every US person with initial jabs and boosters, for free of charge at 80,000 locations across the country.
But the choice has raised concerns about worldwide vaccine equity because the overwhelming majority of the world’s population remains unvaccinated.
The World Health Organization involved a moratorium on COVID-19 vaccine boosters until a minimum of the top of September to enable a minimum of 10 percent of the population of each country within the world to be vaccinated.
US officials said they might seek to expand efforts to supply vaccines for other countries. The United States government has contracted with Pfizer for 500 million doses of its two-dose vaccine to be distributed to other countries.
To date, the US has shipped about 100 million doses to other nations, officials said. New shipments of the Pfizer vaccines have begun in recent days.
Patient data within the US indicate that the overwhelming majority of individuals dying from extreme cases of COVID-19 – now averaging 500 each day – were unvaccinated, officials said, underscoring the effectiveness of the vaccines and therefore the imperative for people to urge the jabs.
“This remains an epidemic of the unvaccinated,” said Jeffrey Zients, head of the White House COVID-19 response team.
“We need to protect the American people and that we need to still do more and more to vaccinate the planet . both are critical.”
New data confirmed that vaccine protection against COVID-19 has decreased for the Delta variant of the virus, CDC Director Dr Rochelle Walensky said.
A US study of nursing homes shows vaccine effectiveness declined to 53 percent with the Delta variant. An Israeli study showed an increased risk of severe disease among those vaccinated earlier within the pandemic.
Dr Anthony Fauci said the info suggested that higher levels of antibodies are required for people to resist the highly contagious Delta variant, hence the advice for boosters.
“You don’t want to seek out yourself behind and playing catch up,” Fauci said.
