The US Centers for Disease Control and Prevention (CDC) has encouraged all American adults to get a booster shot of the Covid-19 vaccine citing the “increased transmissibility” of the Omicron variant of the virus.

“Everyone ages 18 and older should get a booster shot either when they are six months after their initial Pfizer or Moderna series or two months after their initial J&J vaccine,” CDC Director Dr. Rochelle Walensky said in a statement on Monday.

Citing “early data from South Africa” where the variant was first identified earlier this month, Walensky pointed out that the newly-detected strain appears to be more contagious, and noted that its discovery prompted a review of vaccine effectiveness in the US and around the world.

The official also seized the opportunity to call on some 47 million Americans older than 18 who have been reluctant to get vaccinated so far to get the jab “as soon as possible,” as well as to vaccinate their children, “because strong immunity will likely prevent serious illness.” (RT)
