More protection —

The shot should be taken at least four months since the last COVID vaccination.

People ages 65 and up should get another dose of a COVID-19 vaccine this spring, given the age group’s higher risk of severe disease and death from the pandemic virus, the Centers for Disease Control and Prevention announced Wednesday.

Earlier today, an advisory committee for the CDC voted overwhelmingly in favor of recommending the spring booster dose. And late this afternoon, CDC Director Mandy Cohen signed off on the recommendation, allowing boosting to begin.

“Today’s recommendation allows older adults to receive an additional dose of this season’s COVID-19 vaccine to provide added protection,” Cohen said in a statement. “Most COVID-19 deaths and hospitalizations last year were among people 65 years and older. An additional vaccine dose can provide added protection that may have decreased over time for those at highest risk.”

The spring booster will be an additional shot of the 2023–2024 COVID-19 vaccines made by Pfizer-BioNTech, Moderna, and Novavax. The booster dose should be taken after at least four months have passed since a previous COVID-19 vaccination. However, as FDA representative David Kaslow noted in today’s advisory committee meeting, the FDA will likely approve a 2024–2025 version of COVID-19 vaccines for this coming fall. Given that, it’s best for people to get their spring booster dose by the end of June, so they can be ready for another booster before the winter when COVID-19 has generally peaked.

A report published earlier this month by the CDC found that the 2023–2024 COVID-19 vaccine was about 54 percent effective at preventing symptomatic COVID-19 when compared against people who had not received the latest vaccine. However, the CDC estimates that only about 22 percent of adults in the US have gotten a COVID-19 booster this season, and just over 40 percent of people ages 65 and up have gotten the shot.

People over age 65 made up 67 percent of COVID-19 hospitalizations between October 2023 and January 2024, according to CDC data presented at today’s advisory committee meeting. In early January, COVID-19 hospitalizations hit a seasonal high of about 35,000 weekly new admissions per week and nearly 2,500 weekly deaths.

The advisers debated how to word their recommendation for a spring booster and whether getting a booster should require consulting with a health care provider. But, ultimately, the committee decided on a more permissive recommendation, allowing anyone in the age group who wants a booster to be able to freely get one, including at convenient locations, such as local pharmacies.

“Data continues to show the importance of vaccination to protect those most at risk for severe outcomes of COVID-19,” the CDC said in its announcement of the recommendation. “An additional dose of the updated COVID-19 vaccine may restore protection that has waned since a fall vaccine dose, providing increased protection to adults ages 65 years and older.”

The CDC noted that its previous recommendations allow people who are immunocompromised to get additional doses of the COVID-19 vaccines.

CDC to update its COVID isolation guidance, ditching 5-day rule: Report

update —

The agency is reportedly moving from the fixed time to a symptom-based isolation period.

Beth Mole – Feb 13, 2024 9: 42 pm UTC

The Centers for Disease Control and Prevention is preparing to update its COVID-19 isolation guidance, moving from a minimum five-day isolation period to one that is solely determined by symptoms, according to a report from The Washington Post.

Currently, CDC isolation guidance states that people who test positive for COVID-19 should stay home for at least five days, at which point people can end their isolation as long as their symptoms are improving and they have been fever-free for 24 hours.

According to three unnamed officials who spoke with the Post, the CDC will update its guidance to remove the five-day minimum, recommending more simply that people can end their isolation any time after being fever-free for 24 hours without the aid of medication, as long as any other remaining symptoms are mild and improving. The change, which is expected to be released in April, would be the first to loosen the guidance since the end of 2021.

In an email to Ars, a CDC spokesperson did not confirm or deny the report, saying only that, “There are no updates to COVID guidelines to announce at this time. We will continue to make decisions based on the best evidence and science to keep communities healthy and safe.”

The Post notes that the proposed update to the guidance matches updated guidance from California and Oregon, as well as other countries.

The officials who spoke with the outlet noted that the loosened guidelines reflect that most people in the US have developed some level of immunity to the pandemic coronavirus from prior infections and vaccinations.

A report earlier this month found that the 2023–2024 COVID-19 vaccine was about 54 percent effective at preventing symptomatic COVID-19 when compared against people who had not received the latest vaccine. However, the CDC estimates that only about 22 percent of adults have received the updated shot.

Currently, the CDC recommends that people wear a mask for 10 days after testing positive unless they have two negative tests 48 hours apart. The Post reported that it’s unclear if the CDC will update its mask recommendation.
