Covid-19 antibodies reduce faster in men than women –study

Finding has implications for one-size-fits-all approach to vaccine development

Antibody levels against the virus that causes Covid-19 appear to fall faster in men than in women, a study suggests - a finding that could have implications for vaccine research.

Historically, medical research has often taken a one-size-fits-all approach, lumping women and men together despite growing evidence that the sexes differ in how they catch and fight disease. Covid-19 seems to be a case in point, with women more likely to be infected but men thought to be up to twice as likely to die from the virus.
