Is the Thailand Pass still required and do children need a PCR test before entry?

ThailandPass is no longer required. Children under 18 unaccompanied must be vaccinated with one dose of a recognised vaccine to be considered vaccinated. If not they need a PCR or ATK test prior to departure.

If travelling with vaccinated parents there is no requirement for vaccination status. I do not know what the case is if the parents are unvaccinated. Perhaps someone else can confirm if they’d need a test or not.
