The WHO will get right on that.
The countries have all basically rejected the CCP vaccines (Sinovac and Sinopharm).
In Singapore, you won't get in the country unless you've been jabbed. Period. They are very free market and so allow the CCP jabs, but they don't count those who got the CCP jabs within Singapore as being really jabbed.
In Thailand, starting on 11/1, if you've been jabbed, you don't have to do quarantine. If you haven't been jabbed, you'll have to do 10 days of quarantine. Travel within the country is no issue at all if you're jabbed; if you're not jabbed, you may need to get a nose swab and, in some provinces, you may need to do home quarantine. But this is rapidly changing. The jabs started off being mostly Sinovac, but as it rapidly became apparent that the CCP vacs were garbage, they've moved away from them and toward the Astra Zeneca, Pfizer, and (if you are willing to pay a private hospital) Moderna. Interestingly, if a person had the two CCP jabs, they were "encouraged" to come back and get a third jab of either the Astra Zeneca or Pfizer shot.
I shake my head at this...the CCP Sinovac is an inactivated virus vaccine, Astra-Zeneca is a Vector Vaccine, and the Pfizer is an mRNA vaccine. They're not exactly compatible. Nothing but superstition....
Laos is basically completely locked down for foreign visitors (unless you have family there). Laos is primarily using Astra Zeneca or Pfizer.
Vietnam is currently only allowing business travelers who are jabbed. No tourists yet, but that is supposed to change in December.
Cambodia is still locked down but that may start to change in the next few months. Again, a jab will be a must-have for travel.
Malaysia is still locked down for foreign travel. Some talk about opening it up but nothing solid yet.
Indonesia is talking about opening in December for vaccinated travelers.
(Sorry, didn't waste my time checking on Myanmar)
Interestingly, the PRC is ONLY accepting CCP vaccines. I know, this is shocking news.
Bottom line: East Asia / Southeast Asia is pretty much 100% bought into the vaccine message.
As far as vaccine injuries, there is a database out there that I think is accessible to the public, but I haven't looked for it because I don't really care that much. I would look for you, but it's going to written in ภาษาไทย and it really won't do you much good (tbh, my Thai is so crappy, it wouldn't do me that much good either).
I hope that limited info helps you.
Thank you.
