If you do decide to immunize your baby with the live polio vaccine after all, make sure:
To wash your hands carefully after all nappy changes for three months after he or she receives the vaccine.
He or she avoids contact with any of the following groups at high risk of contracting vaccine induced polio:
Those receiving radiotherapy, cytostatic drugs, systemic glucocorticoids, like cortisone, potent cortocosteroids to the skin, those taking ACTH, or other immunosuppressive drugs.
Those with congenital immunodeficiencies.
Those with a history of paralytic disease.
Also make sure to have your own immunity to polio checked out, as well as that of your family.
You might also consider the killed vaccine, which has a better safety record than the live vaccine. If you or any other adults wish to be vaccinated, make sure to have the killed jab, as the live one is considered riskier for adults.
