COVID-19 booster vaccine – level 1

22-09-2021 15:00

A group of scientists from all over the world have some news about a COVID-19 booster vaccine. A booster vaccine is a vaccine which makes a previous vaccine stronger. A vaccine is a medicine that stops you from getting sick.

Some scientists believe that the booster vaccine is important. It protects people from the coronavirus. Then, the latest study says that older COVID-19 vaccines work well. They protect people enough.

A problem is that rich countries buy booster vaccines. Companies cannot make enough vaccines for other countries. Countries must think about other people. They must remember that people in other countries need vaccines, too.

Difficult words:  previous (something that happens before something), enough (as much as people need), protect (to keep safe).

You can watch the original video in the Level 3 section.
