Study finds that low dose allergen injections reduce skin sensitivity to pollen
Researchers are developing a new vaccine for hayfever which could be more effective, less invasive for patients and less expensive than vaccines already available to patients on the NHS. Scientists at Imperial College London and King's College London have carried out a study that showed a significant reduction in skin sensitivity to grass pollen that was associated with an increase in "blocking antibodies" in the bloodstream. The results are so encouraging that King's has today launched a clinical trial in collaboration with Guy's Hospital , working together as part of King's Health Partners. The trial is funded by the Medical Research Council and National Institute for Health Research via the Efficacy and Mechanism Evaluation programme, and will further investigate the vaccine as a potential new hayfever treatment. The researchers say the approach defines a completely new concept in treating allergies and in the future could have an impact on treating other conditions such as asthma and food allergies. Hayfever affects one in four people in the UK. An allergic reaction to grass pollen triggers a blocked or runny nose, sneezing, itchy eyes and in some cases asthma symptoms.
