NEW DELHI: People with COVID-19 infection are more likely to contain strong immunity against the novel coronavirus for as long as a year after they first contract the infection, a study suggested. The study was led by the scientists from the Rockefeller University and it suggested that vaccination also boosts the immunity which people naturally develop after the infection. The study is on bioRxiv ahead of the publication in the peer-reviewed journal.
The team of researchers analysed the antibodies present in the blood of COVID-19 patients and also tracked the evolution. 63 people were examined during the study and their follow ups suggest that antibodies induced by the immune system’s memory B cells get better with time to tackle the SARS-COV2. This suggested that such people were developing a better and improved defence against the novel coronavirus.
The antibodies were further boosted in the individuals who are provided at least one dose of vaccine (Moderna or Pfizer). Such people developed the antibodies which are exceptionally resistant against some of the deadly variants of SARS-COV2 including those which were first isolated in the United Kingdom (UK), South Africa and New York city.
