Governments may create "vaccine passports" to open up society. The passport will show the holder has had the COVID-19 vaccine. It could be put on a smartphone or in the microchip of identity cards. Businesses such as restaurants and theatres might ask people to show their passport. We may need one to watch sporting events. Supporters of the passports say they would let people travel overseas more easily. The World Health Organization is looking at a possible international passport. This would require countries to agree on what kind is necessary.

Opponents of vaccine passports say they are unfair and will create inequality. Many people do not want the vaccine. Some say it goes against their religion. Other people say it has not been tested and is unsafe. Some people worry about the security of their health data. Israel's health minister said those who do not get the jab will be "left behind" in life. In addition, the vaccine is not available to everyone in the world. A human rights professor said: "For many low-income countries, most people won't be vaccinated for many years."
