There have been lots of ads requesting men to donate blood if they have had coronavirus as it can be used to create plasma transfusions to treat those with the virus.
I was intrigued as to why it was only men, and it seems that men produce more antibodies to the disease than women do. I could not work out whether this also means that women are at higher risk of serious illness from covid because they do not produce as many antibodies. However I found some research which says: "In all countries that report death rates by sex, men diagnosed with COVID-19 are more likely to die. " How bizarre is this?
I also found out that, outside of coronavirus issues, women's plasma carries a small risk of causing a lung condition n recipients, so is routinely discarded.
You lives and you learns!
