The concept gained traction after 2 vaccines were introduced to help combat the Coronavirus pandemic in November 2020. A vaccine passport would allow individuals to stop wearing masks if they could they have been inoculated and so aren’t a risk to others. Countries could require foreign visitors to have the passports in order to cross their border and restaurants, theaters and offices may make them mandatory in order to enter their premises. More than a dozen countries including Ghana and Nigeria currently require proof of vaccination against yellow fever before they are issued a visa.
