Antibody from common cold can neutralize COVID-19 and could lead to vaccine that protects against all coronaviruses, new study suggests

An antibody that develops after people have the common cold can neutralize the virus that causes COVID-19, a new study suggests.

Both the common cold and SARS-CoV-2 fall under a family known as coronaviruses, which cause upper-respiratory tract illnesses.

However, it was believed that antibodies that react to ordinary coronaviruses didn’t work against the virus that leads to COVID.
