Which is best OPV or IPV?
Until polio is eradicated globally, OPV is still the main preventative measure against polio. IPV is recommended in addition to OPV and does not replace OPV. IPV is a very safe vaccine in humans, whether used alone or in combination vaccines. No serious adverse events have been reported, only minor side effects.
Is it important to obtain both OPV and IPV Why?
Your child needs both IPV and OPV to ensure his/her protection from polio. OPV is given orally, providing protection in the mouth, in the intestines, and then in the blood. Protection in the mouth and intestines are important as polioviruses infect the mouth and multiply in the intestines.
Why IPV is given after OPV?
Combining OPV and IPV provides stronger protection against polio. IPV strengthens immunity in the blood while OPV strengthens immunity in the gut.
What type of vaccine is OPV?
Oral polio vaccine (OPV) OPV consists of a mixture of live attenuated poliovirus strains of each of the three serotypes, selected by their ability to mimic the immune response following infection with wild polioviruses, but with a significantly reduced incidence of spreading to the central nervous system.
How is inactivated polio vaccine made?
To make IPV, poliovirus is purified and killed with a chemical (formaldehyde). IPV elicits antibodies in the bloodstream, not the intestines. It prevents the virus from traveling through the blood to the brain or spinal cord, thereby preventing paralysis.
What type of vaccine is polio vaccine?

The inactivated polio vaccine (IPV) was available first, given as a shot, in 1955. A more convenient form, called oral polio vaccine (OPV), was given as liquid drops via the mouth. It was developed in 1961. OPV was recommended for use in the United States for almost 40 years, from 1963 until 2000.
