The U.S. has approved a third vaccine for COVID-19

The U.S. health regulator FDA has approved for “emergency” use a vaccine against COVID-19 produced by Johnson & Johnson, the regulator said in a statement.
Three vaccines against coronavirus will now be used in the U.S., the other two being produced by Pfizer and Moderna.
The vaccine is produced by Janssen Pharmaceutica, a division of Johnson & Johnson. Unlike vaccines already approved in the United States, this vaccine is a vector vaccine, similar to Russia’s Sputnik V and the Anglo-Swedish AstraZeneca. The vaccine uses the cold virus and affects the spike protein on the surface of the virus. Unlike other U.S.-approved vaccines, this one requires only one injection rather than two.
Johnson & Johnson plans to deliver up to 20 million doses of the vaccine by the end of March and up to 100 million doses by the end of June.
