Vaccine

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters.

COVID-19 mortality gap between men and women narrowed sharply as the pandemic progressed

Men experienced higher absolute excess mortality than women across many high-income countries during the COVID-19 pandemic, particularly during pre-vaccine mortality peaks. Relative differences were much smaller, showing that sex disparities depended strongly on baseline mortality, age, country, and pandemic phase.
