Save your children from Polio!!!
Explanation:
Prevention of disease spread is accomplished by vaccination. Two kinds of polio vaccines are there. Oral polio vaccine (OPV) and inactivated polio vaccine (IPV), which is injected.
The OPV is less expensive and easier to manage, and can spread immunity beyond the person vaccinated, creating contact immunity. It has been the predominant vaccine used.
However, under conditions of long-term vaccine virus circulation in under-vaccinated populations, mutations can reactivate the virus to produce a polio-inducing strain, while the OPV can also, in rare circumstances, induce polio or persistent asymptomatic infection in vaccinated individuals, particularly those who are immunodeficient.
