This is the VOA Special English Health Report.

Today we have two reports, both about children. We start in Sudan. Health officials are launching a campaign to vaccinate¹ eight million children after a case of polio was reported there.

United Nations and Sudanese agencies will carry out the campaign this week and again in November. Sudan had been polio-free since two thousand five. The new case of wild polio virus was confirmed last month in South Darfur.

Health officials also announced last month that Nigeria has had almost seventy new cases of polio since two thousand five. Those cases, however, were caused by the polio vaccine³ itself.

There are two kinds of polio vaccine. The one given by injection contains killed virus, which cannot cause polio. The one given by mouth contains live but weakened virus. In very rare cases the virus can change and cause polio.

The way to stop the spread now is more vaccinations⁴. But officials worry that people in northern Nigeria may, once again, fear the vaccine. In recent years, local leaders spread stories that Western nations had poisoned the vaccine with the virus that causes AIDS.

Now, an update to our story last month about popular medicines to treat coughs and colds in children. The United States Food and Drug Administration had told parents not to give them to children under age two unless a doctor says to use them.

The F.D.A. gave the advice as it announced a meeting of experts to discuss cold medicines for children. That advisory⁵ committee met last week -- and voted that these drugs should not be given to children under the age of six.

Members said there is not enough evidence to show that these drugs work in children. They called for more research.

The committee also said that liquid medicines should all use the same measurement terms. This could reduce the risk of parents giving their children too much. In rare cases, deaths have been reported from overdoses.

The drug industry says its products are safe and effective for children. But it says parents need to be better educated about how to use them. A week before the meeting, the industry decided⁶ to end sales of cold products for children under two.

The F.D.A. does not have to follow the recommendations of its advisers⁷. Even if the agency restricts use of the drugs, that would not necessarily lead to a ban.

And that’s the VOA Special English Health Report, written by Caty Weaver⁸.
