This is a good one but, are you completely sure China has recovered completely. Maybe not the total population of infected cases but at least, to have reduced infection rate to the least minimum! If this be the case, then the necessity for a vaccine is very much questionable just as many still query the fact behind the Covid19 pandemic.

Vaccination is a very good thing and I won't advise anyone not to be vaccinated but, should it be that, the doubts on long term effect or a possibility of an after effect isn't confirmed following due procedure, then, I'm very much not taking any vaccination coupled with the fact that, vaccine immunity is just for a couple of months with regards to the Covid19 vaccines. Just not cool.
