U.S. : CDC recommends all adults to get Covid19 booster shot
The U.S. Centers for Disease Control and Prevention (CDC) said on Monday everyone aged 18 years and older should get a booster shot, as it looks to tackle a new and highly infectious Omicron Variant strain of the coronavirus that is quickly spreading across the globe.
The U.S. health regulators last week expanded the eligibility for booster shots of Covid-19 vaccines to all adults aged 18 and older either six months after their initial Pfizer or Moderna vaccine doses or two months after their Johnson & Johnson shot.
It will take a few weeks of testing to know for sure whether the Omicron variant is more transmissible than Delta, and whether it evades the protection offered by natural infection or vaccines. Scientists will also be looking to see if it causes more severe disease or evades the effects of treatments.
