Evidence of COVID reinfection without mutations in spike protein

There have been cases of reinfection of SARS-CoV-2 across the globe and including a particular case where it had occurred despite the presence of neutralising antibodies. The study then showed the presence of a mutation in the structural spike protein of the coronavirus as it has happened in most cases of reinfection. However, there is also evidence of SARS-CoV-2 or COVID-19 refinfection without any mutations to the spike protein, a joint study by scientists of CSIR-Centre for Cellular & Molecular Biology (CCMB) and doctors at the Apollo Hospitals here indicated on Wednesday.
