In my little village in Khon Kaen they have stared distribution of vaccines. I got my shot yesterday. It was Sinovac. They said the next shot in 3 weeks will be Astra Zenaca. Followed later with a Pfizer booster when available.
Been looking into mixing vaccines and early data shows it is as least as effective if not more than two doses of the same kind. Mixing a deactivated virus vac (Sinovac, AZ) and and mRNA vac (Pfizer, Moderna) may be more effective. Data is still early stage and limited numbers, but there doesn't seem to a problem with mixing vaccines.
