Vax may protect against other coronaviruses: Study

Washington, October 19

Covid-19 vaccines and prior coronavirus infections can provide broad immunity against other, similar coronaviruses, according to a study.

The findings, published in the Journal of Clinical Investigation, build a rationale for universal coronavirus vaccines that could prove useful in the face of future epidemics.

The study found that plasma from humans who had been vaccinated against SARS-CoV-2 produced antibodies that were cross-reactive, or provided protection, against SARS-CoV-1 and the common cold coronavirus. The researchers found that mice immunised with a SARS-CoV-1 vaccine developed in 2004 generated responses that protected mice from intranasal exposure by SARS-CoV-2. — PTI
