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 reveals how B cells safeguard high-affinity antibodies

A vaccine's ability to generate long-lasting, high-affinity antibodies hinges on a delicate balance. Upon exposure to a vaccine or pathogen, B cells scramble to refine their defenses, rapidly mutating in hopes of generating the most effective antibodies.

U.S. consumers still unaware of raw milk risks despite bird flu findings

Although the Food and Drug Administration (FDA) located H5N1 bird flu virus in samples of raw, or unpasteurized, milk in tests in four states in April 2024, and bird flu has been detected in commercially sold raw milk, many Americans do not know that consuming raw milk and its products poses greater health risks than consuming pasteurized milk and its products, especially for children.
