How do vaccination stops you getting infections?

Vaccination helps prevent infections by stimulating the immune system to recognize and remember specific pathogens, such as viruses or bacteria. When vaccinated, the body produces antibodies and activates immune cells that can quickly respond to future infections by the same pathogen. This adaptive immune response reduces the likelihood of getting sick and can also lessen the severity of illness if infection does occur. Consequently, vaccines play a crucial role in controlling the spread of Infectious Diseases.
