In addition, it had also reinfected 25% to 61% of those who had previously been infected with – and thus, had immunity to – other SARS-CoV-2 viral variants. In short, the viral variants may be partially or fully resistant to natural immunity (as in Manaus), vaccination or antibody therapies. > Effects on antibody therapiesThere is evidence that monoclonal antibody treatment in immunocompromised patients will generate escape virus variants that can render the treatment redundant. In MalaysiaAccording to the Health Ministry, the B.1.1.7 variant was found in two returnees – one in December (2020) and one in February (2021). Racing the virusA global consensus that the main SARS-CoV-2 variants are more transmissible and may evade infection- and vaccine-induced immunity, is emerging.
