Many governments want "vaccine passports". They will show if you have had the COVID-19 vaccine. They might help society to open up. Restaurants might ask people for their passport. Passports would make overseas travel easier. The WHO is looking at a possible international passport.
Opponents of the passports say they are unfair. Many people do not want the vaccine. They say it goes against their religion. Israel's health minister said those who do not get the jab will be "left behind" in life. Not everyone in the world can get the vaccine. Most people in poorer countries will not be vaccinated for many years.
