This is not a question about visa however related in some ways... I read somewhere that thai authorities demand a certificate of yellow fever vaccination is a person has been to certain countries and one of those is Brazil

And on top of everything there is a stamp on my passport which proves I've been there resently, so my question is... Do you happen to know if the guys at the airport really care about it and will make a deal out of it by asking me for the certificate and should a be a good lad and just take the shot and have the certificate with me...

The thing is that the vaccine is quite expensive (not very thou) but most of all I hate shots and needels
