A HK taxi driver today of mature years (65-70?) said he had at last got a first vaccination, because he was afraid of it before. "I hope it wasn't Sinovac, it is almost ineffective against Omicron" said my medical spouse in her inimical sensitive bedside manner. "Oh yes" replied the baba, "They said that only Sinovac is used on older people, the Biontech is bad for older people."
Well I suppose if you have a warehouse full of Sinovac that no-one wants you may as well flog it off to people who don't understand the science. Poor guy thinks he is immune now.
