Vaccinating yourself and your children not only benefits you as individuals but it has a significant impact on the whole community. We rely on herd immunity to protect people who can’t be vaccinated for a variety of reasons.

Herd immunity means having enough of the population vaccinated to reduce the likelihood of person to person spread of preventable disease, to offer some protection to the most vulnerable members of society who can’t be protected in the same way as everyone else. This group includes very young babies, people with reduced immune system function, people receiving chemotherapy, pregnant women and nursing mothers.
