Females might have a better chance to battle against COVID-19 and a few studies have been conducted on this theory for the past two years. A new study from Sweden, however, reveals that the female hormone protects against death from the coronavirus. It observed that among their study population, 14,685 post-menopausal women and had positive numbers recovering from COVID-19. Older studies have also suggested how effective estrogen is in battling COVID before any vaccine was available. Higher levels in women, whether natural or artificially given, result in lower COVID-related deaths.
