They have also stated that, in 90 percent of patients, antibodies were found up to seven months after exposure to the SARS-Cove-2 Virus. The results, published in the European Journal of Immunology, also suggest that age is not an important factor in terms of antibody levels, but the severity of the disease.Our immune system recognizes SARS-Cove-2 as a harmful virus and then produces antibodies in response, which helps fight the virus,” said Mark Valdoven, author of the Medicina Molecular Molecular Molecular João Lobe Antunes in Portugal . This research team monitored antibody levels of more than 300 patients and healthcare workers of the Kovid-19 hospital and over 200 Kovid-19 volunteers who had recovered.
