Overview

Why do we need to get vaccinated?

As we grow older, our ability to fight off infections becomes weaker because our immune system becomes weaker. A weak immune system can make it more likely for us to get sick due to infections like flu, pneumonia or shingles. These infections can worsen existing conditions, lead to hospitalizations and even death. Vaccines are one way in which we can boost our immune system and protect ourselves from infections.

What is a vaccine?

Vaccines are products that protect people against serious and potentially deadly diseases. Unlike most medicines that treat or cure diseases, vaccines prevent them. Most vaccines are given by injection (needle) but some are given orally (by mouth) or nasally (sprayed into the nose).
