The Thai government say, is preferable to take Sinovac as the first and AZ for the 2nd jab.

If our first jab is Sinovac, can we choose the second jab to be remain as Sinovac? or we have to take AZ as the government recommended??

as there are some 31mln sinovac and only some 12mln AZ, they have no choice, but give the second dose of sinovac.

So far you are for sinovac, and not likely to change for a few months. The siam bioscience does expect large backlog. Korea doesn't want to send their AZ, and those 1mln gift from japan was just one off
