Do alpacas hold the key to immunity against Covid-19?

Jun 29, 2020 14:36 IST

Nanobodies or tiny antibodies found in alpacas could hold answers to building immunity against Covid-19 and prevent a possible second wave. Scientists from Sweden and South Africa used nanobodies from 12-year-old Tyson to prevent the virus from infecting a person. The alpaca was injected with virus proteins by scientists at Stockholm's Karolinska Institute. The nanobodies, that bind the same part of the virus as human antibodies, from were isolated Tyson's blood. These nanobodies interfere with the virus causing Covid-19 and prevent it from infecting a host, say scientists. While the findings seem significant, the study is still in its early stages and has not been peer-reviewed yet.
