Both Sinovac and Sinopharm are inactivated viruses (traditional vaccines), rather than mRNA. Possibly less efficacy?
Anyway I have a nice well-heated house in old Beijing and I’ve found a superb app that sends masseuses (guaranteed 24 hour negative nucleic acid test, and you can choose from their galleries) to your gaff, so I’m just playing PS5, eating delivered food from the bossest restaurants, and getting rubdowns from tidy bints.
