For sure going to SF, get a 2 doses vaccine and get quarantined back in Thailand does not make it.

But according to Bangkok Post yesterday "The Maldives is preparing a vaccine tourism programme combined with a staycation package, said Mr Chotechuang.".

So with some adjustments like going to closer country (Singapore ? Maldives ?), get a J&J vaccine and fly back, let's say after July 1st when quarantine won't be mandatory for vaccinated travelers, then definitively I would go for it !

Better to try something rather than waiting and waiting.

How long have private hospitals here been asking the authorization to propose an alternative ?
