Good news for the world. 

But pfizer and moderna are disappointing. mRNA supposed to be fast to develop, but now Apr, apparently still nothing, although they promised omicron-specific vaccine in Mar.

 

Omicron-specific Sinopharm, Sinovac COVID vaccine candidates cleared for clinical trial

BEIJING, April 16 (Reuters) - COVID-19 vaccine candidates developed by a Sinopharm subsidiary and Sinovac Biotech (SVA.O) to target the Omicron variant were approved for clinical trials in Hong Kong, the companies said on Saturday.

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 neutralise the highly transmissible variant.

The two candidates from units of Sinopharm subsidiary China National Biotec Group (CNBG) 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. It did not specify which vaccine products the trial participants would have received before taking the experimental booster, or how many subjects would be recruited.

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.

Let's see how our official judge this. Before that was so obvious bias against Sinopharm and Sinovac.

Wait for the data lo.

No data no talk,

In the case of Sinovac, overseas data was used (for HSA approval) and it was not promising.

Just in time to trial in Shanghai. No excuse of not finding enough samples.

I don't see bias, it is based on data and not skin color. It is already proven that they don't work as well as M & P.

Yeah lor - It is estimated more than 50% of HK people have already been infected.

Or maybe that's why test there.

I recall ever watched a long beedeo of some experts explaining how they beat the covid with some TCM...very convincingly and passionately said until all dragons and tigers cum out of the mouth...maybe it's inside this latest little bottle...😁
