A few countries (Canada, Germany, Italy, UK, Thailand) encouraged their citizens to get mixed COVID-19 vaccines (eg. 1st dose Pfizer, 2nd dose Moderna) during the early stages of vaccination.
Now some countries are announcing that they will only allow visitors who are fully vaccinated, where "fully vaccinated" requires both vaccine shots to be of the same type. In other words, people with mixed vaccines would be prohibited from entering the country.
Which countries are denying entry for people with mixed COVID-19 vaccines?
