What Is Polio?
Reviewed: Dr. Gromatzky
Previous generations used to have to be a lot more aware of the chances of falling very ill than we are. This is because they did not have access to the same medical facilities and equipment that we had. They were more likely to catch diseases, and it was more likely to be very dangerous for them.
One thing that has helped to keep us safe from certain diseases was the introduction of the vaccine. These help to prepare our immune system so it is able to defeat pathogens whenever one might get into the body. There are numerous diseases so far that we have developed a vaccine for, one of which is polio.
