Quadrivalent vaccine

A quadrivalent vaccine helps protect against four different strains of a virus, most commonly the flu. Since flu viruses often change each year, this vaccine targets the most common and dangerous types circulating at the time. By receiving the vaccine, your immune system learns to recognize these strains, reducing the risk of illness or making it milder if you do get sick. It’s a proactive way to reduce flu-related complications and protect both yourself and those around you during flu season.
