    Washington: 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. "Among the general population, many people probably want to know how well protected they are," said Hojun Li from Massachusetts Institute of Technology (MIT)'s Koch Institute for Integrative Cancer Research, US. "But I think where this test might make the biggest difference is for anybody who is receiving chemotherapy, anybody who's on immunosuppressive drugs for rheumatologic disorders or autoimmune diseases, and for anybody who's elderly or doesn't mount good immune responses in general," Li said. Such people might need to be boosted sooner or receive more doses to achieve adequate protection, the researchers said. The test is designed so that different viral spike proteins -- that help the virus to enter and infect the cells -- can be swapped in. Doing so allows to detect immunity against any existing or future variant of SARS-CoV-2, the researchers said. The researchers have filed for a patent on the technology and are now hoping to partner with a diagnostic company that could manufacture the devices and seek approval from the US Food and Drug Administration (FDA). Currently, the gold standard approach to measuring immunity invo ...
