Are you saying US Pfizer and Modena vaccine are failure? Check with proper facts before spew nonsense...So it is nearly impossible to stop bcs you live in a failed country that not smart enough to control Covid. SG is failed state,too, she (SG) survive till now due to US's protection .
Of course Sinovacs are failed vaccine, too, thats why Sinovac can't save Singapore (SG) .
As I said, I haven't take any vaccine shots yet bcs I don't wanna be a lab mouse for the current unsafe vacines, at least half of people in my city also haven't got any vaccine shots yet, Yeahh, we still go to work, kids still go to school. Nothing big happen in my city now.
Some guys here will say abt Covid cases in Ho Chi Minh city again, but there are no important factories in Ho Chi Minh city. The city is just a place for tourism and trading, plus abt 1,5 to 2 million Hoa ethnic and Chinese are living there. Ho Chi Minh city is big, but not important to VN.
Singapore never make Chinese vaccine as their main covid-19 vaccine for their population.
So many BS idiot brag how great Modena and Pfizer vaccine. Welcome to the reality of US failure!
