Boston, Aug 10 (PTI) Researchers in the US have developed an easy-to-use test that can predict the degree of immune protection people have against COVID-19, either from vaccination, infection, or a combination of the two.

Easy access to this kind of test could help people determine what kind of precautions they should take against COVID-19 infection, such as getting an additional booster shot, the researchers said.

Described in the journal Cell Reports Methods, the test measures the level of neutralising antibodies -- responsible for defending cells from the virus -- that target SARS-CoV-2 in a blood sample.
