All American adults became eligible for booster doses of coronavirus vaccines earlier this month, but the CDC previously focused on the most vulnerable age group — saying people over 50 should make sure to get boosted, while others had the option.

Scientists say the omicron variant’s high number of mutations could make it highly transmissible and better able to penetrate immune defenses, but much remains unknown. Experts predict vaccines will still provide at least some protection, and the president emphasized Monday from the White House that shots remain the best way to prepare.
