Do you really need to have vaccines before you travel aboard during covid19?

Question

I don’t know if it’s true or not.

Do you need to have vaccines before to fly or you don’t have too? 

Update:

Btw I’m from and live in uk

Update 2:

Cause I don’t personally really want I have vaccines.

Answer 1

Not yet but you probably will after you have an opportunity to get vaccinated.

Answer 2

Different rules apply for different countries, you need to check days before you travel for both countries - they  can change at any time. That could mean getting tested, or having to quarantine  on arrival. There are NO vaccinations carried out, as of yet, so that will not apply right now.
