Immunizing children

Polio mainly affects children under five years old. There is no cure for polio, but it can be prevented. Polio vaccine, given multiple times, can protect a child for life. As long as a single child remains infected, children in all countries are at risk of contracting polio. Failure to eradicate polio from its last remaining strongholds—Afghanistan, Nigeria and Pakistan—could result in as many as 200 000 new cases each year, within 10 years, worldwide.
