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.

National follow-up study identifies risk factors for a prolonged COVID-19 recovery

In one of the largest follow-up studies to date, involving 25 pediatric hospitals, more than a quarter of children and adolescents hospitalized with coronavirus infection early in the pandemic still had health problems two to four months later, either persisting symptoms or activity impairment. The study, led by Boston Children's Hospital, is published August 12 in the journal Pediatrics.
