China may be developing a booster shot for people who have been fully vaccinated against COVID-19 with the arguably less effective jabs of Sinopharm and Sinovac.
China’s Shanghai Fosun Pharmaceutical (Fosun Pharma) has partnered with BioNTech to develop an mRNA booster vaccine. The shot is now in the administrative review stage following an expert panel review conducted by Chinese drug regulators, Caixin Global reported.
The booster, which is expected to have the brand name Comirnaty, may begin domestic trial production by the end of August and could be offered for free to people who have received the Sinopharm and Sinovac shots.
Health experts said the development of the booster shot could be seen as a blow to the Chinese government which has been touting the effectiveness of its vaccines.
“I think scientists in China also realized the fact of low antibody [levels] in the serum of Sinovac or Sinopharm vaccines. Therefore, they may suggest the Chinese government has another shot as a booster," Shih Shin-ru, director of the Research Center for Emerging Viral Infections, told VOA Mandarin.
Talks about a booster vaccine in China come after a Hong Kong study published in The Lancet on July 15 found that the COVID-19 vaccine developed by Pfizer-BioNTech gave recipients 10 times more antibody levels than the Sinovac COVID-19 vaccine.
Researchers said antibody levels in 63 participants who received the Pfizer shot “rose substantially after the first dose and then rose again after the second dose of vaccination.” In comparison, antibody levels for the 30 healthcare workers who received the Sinovac jab “had low antibody concentrations… after the first dose, rising to moderate concentrations after the second dose,” the study found.
In another study published on medRxiv Monday, researchers found that the Sinopharm COVID-19 vaccine had a weaker antibody response against the more contagious Delta variant.
According to the scientists, the antibody levels in people who were administered the Sinopharm shot showed a 1.38-fold reduction to the Delta variant compared to the original strain of COVID-19. The study also found that the shot showed a 10-fold decrease in antibody levels in people who developed the Beta variant.

that's not quite the article tho. They are saying that from next year they want labs to move to broader panels that will check for influenza as well.

We can't be proactive?

so basically EUA requires safety & efficacy alone, Full Approval i addition to those 2 things, requires data on how long immunity will last

This is more than just a virus eh.
This is a test of how much freedoms people willing to give up. So go ahead and muzzle yourself literally and figuratively.
Banning people for 'wrongthink' is exactly the kinda mentality that gave rise to Nazi-ism.
Your rights stop where it infringes on someone's else's.
