My wife is Thai, We were in Thailand in early 2020, Although as the virus spread quite rapidly, we were in the south, not so densely populated and very little infection, in early March we travelled back to Bangkok for a couple of days before returning to the UK (just made it lol), again even in one of the most populated cities with all it's problems of pollution due to traffic, here people were wearing masks long before Covid, at this time the Thai people used masks more frequently than before, all shops were checking temperatures of all shoppers, ensuring everybody used hand sanitiser etc. & at that time their infection & certainly the death rate was one of the lowest in South East Asia, if not the world, here in the UK we did not do anything constructive until a month or two later, although Bangkok is one of the biggest transit cities in that area with boarders where people often cross to do business & work, their spike although still pretty small has been in the last few months, according to some sources I have regular contact with this is mainly due to complacency amongst the population especially the younger generation.
These measures do work, the general consensus is that vaccination has reduced the deaths & serious illnesses, I apparently am asymptomatic, but still had my injections and will have the booster when it's my turn, the only time I would wait for any future injection is if I could be sure that it would benefit some other unfortunate person who may need it more.
My wife & I both hate wearing masks, I do find it uncomfortable to wear & my wife is still recovering from long Covid which makes it more difficult to breath, however, we continue to wear them for other peoples protection even if it is only marginal protection.
