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.

What are Vaccines?

There are several diseases like Diphtheria, whooping cough (pertussis), measles, mumps, Yellow fever, small pox and German measles (rubella) that are unfamiliar to many these days.

Study evaluates SARS-CoV-2-specific antibody response in human milk

In a recent study published in the journal Communications Biology, researchers investigated the effect of the coronavirus disease 2019 (COVID-19) vaccine booster on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibodies in the milk of lactating women. Additionally, they explored whether the booster-induced antibody response differed from the homologous and heterologous boosting schedule of their primary vaccination.
