  • Senior getting a flu shot


Immunization saves lives and helps keep deadly viruses and bacteria under control. In the last 50 years, immunization has saved more lives in Canada than any other health intervention. The Northwestern Health Unit offers immunization services to prevent the spread of infectious diseases.
A vaccine-preventable disease can strike at any time in Canada because all of these diseases still circulate in the world. The germs that cause these diseases will find those who are not protected. Diseases can spread through the air we breathe or through the environment. You cannot prevent contact between others who may not be immunized (you won’t even know), so the best way to stay safe is to be immunized.
Vaccines prevent the spread of disease from one person to another. The more people that are immunized, the less chance a disease has to circulate. When you get immunized from a specific disease, it not only protects you but it also helps protect your loved ones. When more and more people in a community also get immunized, it helps protect those who have very weak immune systems. When immunization rates are low, the diseases and related deaths increase in frequency

Public Health Question
  • Q:
    I am a healthy person and never get sick. Why do I need a flu shot?
    ​A healthy person may not get sick but they are capable of picking up the influenza virus, having very mild symptoms and passing on the virus to those individuals around them that can’t fight off the infection.
