The US has approved a COVID-19 booster dose for people with weakened immune systems. Many other countries have also begun giving a booster dose to groups of people with a compromised immune system.

Chile began giving booster shots on Wednesday to people vaccinated with the Chinese Sinovac vaccine, including the elderly.
