To each their own, that we can agree on.
Just want to point out that smoking and drinking related deaths are hardly only the individuals that suffer. Try telling that to the victims of drink driving or alcohol fueled violence or the people who suffer from 2nd hand smoke.
China's Zero-Covid strategy is a "candle strategy", lighting others, burning one's own. At this stage, it is very hard to ask others to follow your choice. So, if you feel their choices impact you more then block them from entering your country. Period!I do not agree. The reason is that your choice impacts me more than my choice impacts you. Our choices do not have nearly equal impacts, so we do not deserve equal freedom to choose one or the other.
The reason of course is that the virus is contagious. Opening up (your choice) increases my chance of dying. Your "freedom" comes at my expense, and I object to that. My choice (of zero Covid) is morally superior, as it does not increase your risk of death from the virus.
A key advantage of the aerosolized version of the CanSino vaccine is it's lower dosage, around 1/5 of the injection version, which means 5 times more booster shots.
Inhaled vax typically don't work well compared to injected vax. FluMist does not work as well as injected vax. NasoVax does not work as well as injected vax. CanSino is not an effective vax to begin with, only 65%. It would never be approved in the west.
