Took my eldest to Spain at 9 weeks old. Had the 8 weeks vaccines, she was hood as gold
Took our baby abroad at 10 weeks. Just trust your instincts
My lg is not vaccinated at all and we travel a lot, never did she have any issues/caught anything
The vaccinations target preventable serious infections. So they won’t protect against common things. Even going out to the shops nowadays can be risky with the decreased uptake of vaccinations. The risk should be comparable if you want to go abroad.
