“booster shot”可以造什么句，booster shot造句

Spokesmen for Merck and Glaxo say all indications are that their vaccines are safe and effective, and there is no evidence that a booster shot will be needed.

Some experts say booster shots might still be needed every 10 years or so.

"booster shot: an additional dose of an immunizing agent, such as a vaccine or toxoid, given at a time after the initial dose to sustain the immune response elicited by the previous dose of the same agent."

A tetanus booster shot may be required if a wound is deep or dirty.
