Members of the White House COVID committee today urged people to get current with their COVID-19 vaccination and boosters, as a more transmissible Omicron variant expands its dominance across much of the country.In international developments, the World Health Organization (WHO) today said its emergency committee met last week and urged the agency to keep the public health emergency of international concern designation in place.Feds: Best booster timing is nowAt a briefing today, Ashish Jha, MD, the White House committee's coordinator, said officials have been closely tracking the rapidly evolving BA.4 and BA.5 subvariants, which are the most transmissible forms of Omicron and can evade protection from earlier infection and vaccines.
He and his team, however, emphasized that the vaccination can still protect against severe outcomes.Jha said if people haven't gotten a vaccine dose in 2022, it's time to get one now. "It could save your life," he said.He acknowledged that some people may be holding off on getting boosted, anticipating a rise in COVID activity in the fall, while others might be waiting for an Omicron-specific booster.
Jha said getting boosted now won't preclude people from getting another dose in the fall or winter when the Omicron-specific version is expected to be available.Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky, MD, MPH, said proportions of BA.4 and BA.5 are increasing, especially, with the two related subvariants making up about 81% of circulating viruses, up significantly from about 70% last week.
Hospitalizations are slightly up, and 32% of the US population lives in a high community transmission area, a metric that triggers a CDC recommendation for indoor masking.As
