Mandatory: Israel (Pfizer head was denied entry previously because he wasn't vaccinated)

Vaccine Passports:

• Canada (soon)
• Japan (in July)
• EU (edit: EUDCC, passport-like system, but vaccine not required. My post below has more info)
• ASEAN (Singapore, Brunei, Malaysia, Thailand, Philippines, Indonesia, Vietnam, Laos, Cambodia, Myanmar)

Travel without vaccine passport may still be allowed, but with more restrictions (quarantine). Union nations may have individual rules, although still use the passports.
