The US tests new versions of COVID-19 vaccines

Researchers are studying the potential of adjusted vaccines to fight new strains of coronavirus.

New versions of COVID-19 vaccines are currently being tested in the US if they are needed to protect against mutated versions of the virus.

The vaccines offered in the US offer powerful protection, including against some variants that are becoming more common.

But viruses are constantly evolving, and countries worldwide are striving to vaccinate millions of people and suppress the coronavirus before new mutants appear.

Hoping to get ahead of these changes, the researchers are watching to see if the adjusted versions of Moderna and Pfizer vaccines can protect against one alarming strain identified in South Africa.
