A single vaccine could be enough to ward off the threat of a number of allergic diseases including hay fever, asthma and eczema

Human tests have been conducted and were successful and the researchers said that the vaccine should be available in the next four to five years.
The director of Research at Asthma UK, Leanne Metcalf said that the vaccine could be a boon for all those who are suffering from multiple allergies. “Over three quarters of people with asthma also have an allergy, which can often trigger their asthma symptoms. We are, therefore, excited about the potential of this vaccine to make a real difference to people with asthma and allergies, especially as it has been shown in clinical trials to have relatively few side effects”, Metcalf added.
