Covid-19 triggers antibodies from previous coronavirus infections, says study
HOUSTON : People with COVID-19 may rely on antibodies created during infections from earlier coronaviruses to help fight the disease, says a new study that may partially explain the difference in symptom severity between old and young patients.The study, published in the journal Cell Reports Medicine, noted that humans have navigated at least six other types of coronaviruses before SARS-CoV-2 -- the virus that causes COVID-19."Our results suggest that the COVID-19 virus may awaken an antibody response that existed in humans prior to our current pandemic, meaning that we might already have some degree of pre-existing immunity to this virus," said John Altin, a co-author of the study from the Translational Genomics Research Institute (TGen)
