There are two types of vaccine that protect against polio: inactivated poliovirus vaccine (IPV) and oral poliovirus vaccine (OPV). IPV is given as an injection in the leg or arm, depending on the patient's age. Polio vaccine may be given at the same time as other vaccines. Most people should get polio vaccine when they are children. Children get 4 doses of IPV at these ages: 2 months, 4 months, 6-18 months, and a booster dose at 4-6 years. OPV has not been used in the United States since 2000 but is still used in many parts of the world. 1 What Everyone Should Know Basic information for people interested in the vaccine... (https://www.cdc.gov/vaccines/vpd/polio/public/index.html) These antibodies protect you from illness should you become infected with the polio virus. The vaccine is safe to be given if you are pregnant or breast-feeding. Before 2004, the polio vaccine was given as drops into the mouth. It is now always given as an injection. If you have previously started a course of polio immunisation with oral vaccine you can finish off the course with polio injections. You do not need to start again. Polio immunisation timetable The polio vaccine is used to help prevent these diseases in children and adults. This vaccine works by exposing you to a small dose of the virus, which causes the body to develop immunity to the disease. Polio mainly affects children under 5 years of age. Polio is very infectious. The infection usually spreads from person to person through contact with the stools (faeces) of an infected person. MMR is a two-shot series of vaccines usually given during childhood. A child should receive the first shot when he is between 12-15 months, and the second when he's between 4-6 years of age. If you're not sure if you have had the diseases or the vaccines (prior to 1971 it was given in three separate shots), you can get the MMR vaccine as an adult. Talk to your doctor about it if: You were born after 1956. (If you were born during or before 1956, you are presumed to be immune, because many children had the diseases then.) In 2000, the U.S. switched to the inactivated polio vaccine (IPV). Using an inactive (dead) form of the virus that cannot cause polio, the IPV is given as a shot in the arm or leg. Who Needs the Polio Vaccine. Most people should get the polio vaccine when they are children. Children should be vaccinated with four doses of IPV at the following ages: Meningococcal vaccine is also recommended for children aged 2 months through 18 years who travel to or reside in areas where N. meningitidis is hyperendemic or epidemic; for these children, providers should take care to use a meningococcal vaccine that is licensed for the child's age group and contains all 4 serotypes (A, C, Y, W-135). The first polio vaccine was the inactivated polio vaccine. It was developed by Jonas Salk and came into use in 1955. The oral polio vaccine was developed by Albert Sabin and came into commercial use in 1961. It would only take one person infected with polio coming from another country to bring the disease back here if we were not protected by vaccination. If the effort to eliminate the disease from the world is successful, some day we won't need polio vaccine. Until then, we need to keep getting our children vaccinated. Polio vaccine Like any medicine, there's a very small chance that the polio vaccine could cause a serious reaction. Keep in mind that getting the polio vaccine is much safer than getting polio.
