My daughter was vaccinated 1 time against polio when she was a baby, but never again after that. Now she is 24 years old. Is there a risk she can get it still being an adult and does she need a reinforment still?
The Polio vaccine is typically given as four doses...2 months, 4 months, 6 months and again at 4-6 years. To have full protection, a person should have all four doses. There haven't been any outbreaks of Polio in the US in decades (since it's still given to most children as part of their childhood immunizations) but there are still outbreaks in other parts of the World even today (right now in Russia and possibly in Central Asian countries). She will probably be fine as long as she doesn't do any overseas travel, but if she does, she would want to complete the series before traveling to an area with an outbreak.
