New Hayfever Vaccine Treatment may be more Helpful and Less Costly

(Best Syndication News) - UK scientists from Imperial College London and King's College London are investigating a new hayfever vaccine that might be more effective at blocking antibodies in the bloodstream and may cost less than current treatments. The clinical trial is being funded by the Medical Research Council and National Institute for Health Research via the Efficacy and Mechanism Evaluation programme to confirm if the new hayfever vaccine is a viable option.

The current immunotherapy vaccine used to treat severe hay fever cases requires high doses of the allergen delivered under the skin and sometimes as a tablet or drops. The injections usually required are in large quantities, and the tablets or drops must be taken continuously to slow the allergic symptoms. The treatments can often be expensive over the long run.

The trial came after the researchers conducted a study on a new method and doseage amount for the hayfever vaccine. The UK researchers published their study findings in the Journal of Allergy and Clinical Immunology. In their study, they gave a series of very low dose allergen injection under the higher layer of skin instead of subcutaneously. The injections were less than a 1000th of the typical dose that is usually given. The results showed a 90 percent reduction in skin reaction to grass pollen. The study participants did not suffer hayfever symptoms from the injections and they did not report any undesirable side effects.

The researchers suspect that injecting into a different layer of skin had contributed to the prevention of hayfever symptoms. They also want to see if they can turn off the grass allergy in the nose area. They launched the PollenLITE clinical trial today to see if they can have even more success with the new method for applying the injections.

The researchers suggest that a new vaccine could also be developed to help treat other allergies in the future. They theorize that a treatment for conditions such as asthma and food allergies could be developed into an immunotherapy vaccine.
