It is important to vaccinate to prevent getting sick or spreading the disease to others. Vaccinations are usually given as a shot or injection, but can also be given by a nasal spray or pill. It is recommended to get vaccinated regularly, especially for children and adults who work in healthcare or travel to different countries.
