Polio is a highly contagious virus that can cause paralysis and even death in young children. The Polio vaccine is one of the most successful public health interventions of all time, having saved millions of lives around the world. It has been used since 1955 and has been instrumental in eradicating polio from many countries.
The Polio vaccine works by introducing a weakened form of the virus into the body, which stimulates an immune response without causing disease. This means that when a person is exposed to wild polio virus, their immune system will recognize it and be able to fight it off before it causes any harm. Vaccination against polio is safe and effective, with only minor side effects such as soreness at the injection site being reported.
The Polio vaccine has been instrumental in reducing cases of polio to near-zero levels in many countries, including the United States where there have been no cases since 1979. Despite this success, there are still pockets of infection around the world where vaccination rates remain
