Influenza vaccines

Influenza vaccines are designed to protect against the flu, a contagious viral infection that can cause severe illness. Each year, the vaccine is updated to target the most common strains of the virus, as these can change. There are different types of flu vaccines, including injections and nasal sprays. Vaccination stimulates the immune system to recognize and fight the virus, reducing the risk of infection and potential complications. It’s recommended annually, especially for high-risk groups like the elderly and those with certain health conditions, as immunity decreases over time and the virus evolves.
