Not sure why Myanmar only requested for purchases and donations until recently. Anyway 2.5 millions doses of Sinopharm were donated to Myanmar.
Zhong also cited a follow-up study on Sinovac’s early stage clinical trials that found a
twentyfold increase in neutralising antibody levels – indicating immune response – in people who were given a third dose of the Sinovac jab, nine months after their second. In elderly people it went up 30 times.
A study published last month, co-led by Sinovac, found that a third dose of the vaccine given six or more months after the second jab could boost the concentration of
antibodies by three to five times. Antibody levels were found to have declined substantially six months after two doses were given, but the study concluded that a third dose resulted in a “strong boost in immune response”. The research has not been peer-reviewed and was posted on preprint server medRxiv.org.
Other countries are also looking at mixing vaccines. Last week, Turkish researchers said a study of more than 30 million inoculated people found that
three doses of inactivated vaccines offered more protection than receiving an mRNA vaccine booster shot after two inactivated vaccine doses.
On Friday, Zhong again said that Chinese vaccines still offered protection against the Delta strain, though they were not as effective. He cited a small study in Guangzhou during a
Delta outbreak earlier this year that found the Chinese vaccines were 59 per cent effective in preventing infection, and 70 per cent effective in preventing moderate cases. No serious cases were found among the 74 vaccinated people in the study.
Sour grapes. Just hilarious, facts speak louder than words. Most SEA nations continue to procure Chinese vaccines. It doesn't mean these countries wouldn't use other vaccines.
