Why is COVID insurance required for vaccinated travelers entering Thailand but not for renewing a retirement visa?

The requirement for COVID insurance when entering Thailand, even for vaccinated travelers, has raised questions among expats. Although it may seem odd that vaccinated individuals must have this insurance while renewing an OA retirement visa doesn't require it, the regulations differ based on the Ministry of Foreign Affairs for entry and local immigration offices for residency. Concerns about the costs associated with potential COVID hospitalizations have been shared, emphasizing that vaccinated individuals can still contract the virus and may incur significant medical expenses. The conversation also touches on the financial burden of insurance for older travelers and the perception of insurance as a necessary cost.
