OPV (Oral Polio Vaccine) What is OPV and what are its side effects Usually four doses of this polio
vaccine are administered to the child: at two, three and four months and
then again between three and five years. It is a very safe vaccine and
the child rarely has any reactions following a dose. However, there is
a 1 in 8.7 million risk of paralysis and a negligible risk that a susceptible
member of the household might contract polio from an immunized child.
When should OPV not be given Doctors should refrain from giving
the live oral polio vaccine to children who have cancer, whose immune systems
are weakened because they are ill or under medication. It is also not advisable
for babies who live in a household where there is a person whose immune
system is deficient. In such cases, it is advisable to administer an injectable,
inactivated vaccine.
