According to new research, the Alberta Health Services say that routine immunizations have all but wiped out some of the most harmful subtypes of bacteria.

In 2002, Alberta became the first province in Canada to introduce a vaccine that targets the seven most common and harmful subtypes of bacteria.

The bacterium included in the vaccine cause pneumonia, meningitis, and other infections known as Invasive Pneumococcal Disease.
