Just had my second Pfizer injection today 

And received the Pfizer Certificate confirming this from the hospital concerned 

Can anyone confirm how long is the Certificate valid for I ould have asked when there 

Thank-you 

for international travel 270 days from the second jab (to some countries might be shorter).

Might be changing in the future, depending on new dangerous mutations.

For other purpose valid without limit. Again, until the booster shot become obligatory
