Scientists worldwide are racing to study upgraded injections against Omicron, as data indicated that antibodies elicited by vaccines based on older strains show weaker activity to neutralize the highly transmissible variant.
The two candidates from units of Sinopharm subsidiary China National Biotec Group and one from Sinovac contain inactivated or "killed" coronavirus and are similar to vaccines that the companies are supplying in China and overseas, the companies said in statements.The Sinopharm candidates will be tested as boosters in adults who have already received two or three vaccine doses, CNBG said.
Sinovac said it will push forward studies in its existing CoronaVac vaccine's protection against emerging variants. A Chinese study showed that a fourth dose of BBIBP-CorV, an existing Sinopharm COVID vaccine, did not significantly lift antibody levels against Omicron when administered six months after a third booster dose to a regular two-dose regimen.
While the fourth dose restored antibody levels to around the peaks that followed the third dose, researchers said new vaccines would offer a better alternative as future boosters.RELATED IMAGES
I don't care what anyone says. My mask will stay on in public places until this endemic pandemic is no more. Another advantage to wearing a mask is that I haven't caught a cold or anything else in the past winter seasons since Covid started. This will be my lifetime insurance.
I got a vaccine it’s called eating healthy and living healthy.. I administer one tall glass of water to everyone, it’s up to them to follow up with more clean water every day.. best of all. I ain’t asking cash
I’m sure justin will make sure the vaccines from his beloved basic dictatorship will be approved posthaste!
Can we send all the woke liberals to the trial first?
