‘Sex distinction in immune response to COVID-19 decoded’

New York, August 26  

Women with COVID-19 mount a extra sturdy and sustained immune response by way of the physique’s T cells than males, in accordance with a examine that will assist information a sex-based strategy to the remedy and take care of these contaminated with the novel coronavirus.
