“加强” literally means “to boost, reinforce,” and “针”means “injection.” This term, translated as “a booster shot,” refers to an additional shot administered when a person has completed their vaccine series and protection against the virus has decreased over time. Additional doses are administered to people with moderately to severely compromised immune systems. For example, COVID vaccine booster shots are recommended for adults aged over 65, people with underlying medical conditions and those who work or live in high-risk settings.

Yeah, I finished taking two jabs in April. Now I’m planning to ask about it at the community health center in a couple of days.
