The Centers for Disease Control and Prevention strengthened its Covid-19 booster-shot recommendations, reflecting the potential threat the new Omicron variant poses to the pandemic response in the U.S. and world-wide.
The CDC on Monday recommended that everyone 18 and older get an additional shot after completing a first course of Covid-19 vaccination. The agency earlier this month encouraged boosters only for those 50 and above, adding that people ages 18 and above could get an additional dose.
