T cells induced by COVID-19 infection respond to new virus variants – U.S. study

According to a U.S. laboratory study released, T cells are a critical component of the  immune system that combats infection that fought off the original version of coronavirus and it  also protects against more mutated version of the virus. Immune protection from antibodies and  vaccines can be undermined due to certain variants of the COVID-19, recent studies have  reported. T-cells play an important protective role and researchers have found that the T cell  responses remained largely intact and could recognise all new virus variants. More research is  needed on the continued monitoring for variants that exasperated both T cell protection and  antibody.
