Vaccines - The Basics

Why We Need Vaccines

Vaccines are used to boost your immune system and prevent serious, life-threatening diseases.

For a few weeks after birth, babies have some protection from germs that cause diseases. This protection is passed from their mother through the placenta before birth. After a short period, this natural protection goes away.

Vaccines help protect against many diseases that used to be much more common. Examples include tetanus, diphtheria, mumps, measles, pertussis (whooping cough), meningitis, and polio. Many of these infections can cause serious or life-threatening illnesses and may lead to lifelong health problems. Because of vaccines, many of these illnesses are now rare.

Yes, the improvement in our expected longevity and our ability to live a life free of infectious diseases has been impressive, but we are at serious risk of seeing many of these diseases make a comeback.








With increasing antibiotic resistance amongst pneumonia causing organisms, vaccines offer a way to prevent infection from even these resistant bacteria.
