A group of scientists from all over the world said that COVID-19 vaccines worked well. It was not necessary to use booster vaccines.

Many people already argue that it is not necessary to use booster vaccines, and the news will make the argument even more interesting.

Scientists used data from many studies and tests. They said that countries should keep vaccinating people who did not get a vaccine yet instead of giving booster vaccines to people who already were vaccinated.

Another problem was that if rich countries use booster vaccines, companies will not have enough capacity to make the other vaccines, too. This is important that countries started to think globally and did not focus on only their own problems.

Difficult words: booster vaccine (an extra vaccine which strengthens an earlier vaccine), capacity (the amount of something which a company makes), globally (relating to the whole world).
