Immunogenicity data from Sinopharm's 2nd gen broad spectrum vaccine when used as booster to Sinopharm's inactivated vaccine. Looks like its broad spectrum doesn't cover Omicron as well as earlier variants. The data is roughly comparable to BNT when used as a booster to inactivated vaccines. Bad news.
Anyway, the situation is quite serious at the moment. China really is less prepared than it could be for this wave. The conservativeness of China's vaccination policy has been astonishing. From the lengthy (6 month) time gap requirement between 2nd shot and booster shot to the reluctance to approve homologous boosting. Someone later need to explain their decision making process.
