Boosters

Boosters are additional doses of a vaccine given after the initial vaccination series to enhance or extend immunity. They stimulate the immune system to recognize and fight the targeted pathogen more effectively, especially as immunity from the original doses may wane over time. By boosting the body's defense, boosters help maintain protection against diseases like COVID-19, ensuring continued safety and reducing the risk of severe illness. They are a common tool in public health to keep populations protected as pathogens evolve or immunity decreases.
