A new study on coronavirus has found that the antibody that remains in the blood after a person contracted a common cold, which often is a symptom of mild strain coronavirus can fight SARS-CoV-2, the virus that causes Covid-19 as well, reported IE. The anti-bodies are warriors that the immune system creates when a virus infects a person.
The researchers at Francis Crick University and University College London established this after they developed highly sensitive Covid-19 antibody tests. On comparing blood samples of both Covid-19 patients and the ones who never have had the disease they found some subjects already have antibodies in their blood that can target SARS-CoC-2 even when they have no history of contracting Covid-19. They concluded that the antibodies were formed on exposure to other viruses with structural similarities with the virus of Covid-19, SARS-CoV-2.
To re-state their findings, they examined 300 blood samples that they collected before the Covid-19 pandemic started in a period between 2011 and 2018. Barring few, most had antibodies that reacted with common cold coronaviruses. Among the 300 samples, 1 in 20 adults formed antibodies that cross-reacted with Covid-19 causing SARS-CoV-2 and these adults do not have a history of recent infection with common cold coronaviruses. Such cross-reactive antibodies are more common in children aged 6 to 16.
