Is oral polio vaccine necessary?
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 OK to have polio vaccine twice?
Yes. Getting an extra dose of vaccine when an immunization history is unknown is not harmful. It is better to ensure protection by getting the vaccine than risk leaving your child unprotected. You may be able to locate your child’s record if you have lost it.
Why polio vaccine is given again and again?
The oral polio vaccine is effective as it not only protects the children from contracting the virus, but also prevents them from carrying the virus in their intestines. Several doses need to be given spaced apart to build sufficient immunity, especially in areas where poor nutrition can weaken immune systems.
What happens if you get vaccinated twice?
Is there any danger from receiving extra doses of a vaccine? Most of the time, your risk of serious side effects does not increase if you get extra doses of a vaccine. Getting extra doses of oral vaccines, such as rotavirus or typhoid, is not known to cause any problems.
Is one drop of polio vaccine enough?
OPV is the WHO-recommended vaccine for the global eradication of polio. Each child requires just two drops per dose to be immunized against polio. Usually administered four times if the EPI schedule is followed, OPV is safe and effective in providing protection against the paralyzing poliovirus.
Does polio vaccine last for life?
Booster doses of the vaccine are recommended every 10 years for at-risk adults. If you are travelling overseas, speak to your doctor before you go about whether you need a booster polio immunisation for the countries you are visiting.
Do adults need polio booster?
