If you were first in line to get your COVID-19 vaccination, you’d better also be eager to receive a booster shot. The Omicron variant is putting the current COVID-19 vaccine through a tough test and some countries are already thinking beyond the first two shots by requiring booster shots from international travelers.
Croatia is one of the first country to have set a booster shot requirement for international travelers. The Balkan nations asks that travelers provide a “certificate not older than 365 days of receipt of two doses of vaccine used in EU Member States (Pfizer, Moderna, AstaZeneca, Gamaleya, Sinopharm) or vaccines approved by the World Health Organization for emergency use (Serum Institute of India — Covishield, Bharat Biotech — Covaxin, Sinovac — CoronaVac) or presentation of a certificate not older than 365 days of receipt one dose of vaccine received in one dose (Janssen / Johnson & Johnson) if 14 days have passed since receiving that one dose,” according to the Croatian government website.
