  Kids with asthma could get relief
Updated 14 April 2003, 15.29
Kids with asthma use inhalers to help them breathe
Kids with a certain type of asthma may soon start finding breathing a bit easier.

A new vaccine has been created which helps anyone who gets asthma from being allergic to cats.

Allergies often trigger asthma - which is when people's airways tighten and they find it hard to breathe.

It makes them wheeze and sometimes means they find it hard to take part in sports.

But when the new vaccine was tested on people with asthma, the scientists at Imperial College in London found it made them feel better.

They gave them injections of tiny doses of the substance they're allergic to.

Eases symptoms

That stimulates the body's natural defences to get used to their allergy and therefore not get bad asthma any more.

It's not a cure, but it does stop them from getting severe symptoms.

The scientists are now trying to make the vaccine work for people whose asthma is caused by allergies to dust mites and pollen as well.

They hope it will be available within five years.
