London: Scientists are developing a new and cheaper vaccine for hay fever which they say would bring swift and lasting relief to the sufferers. The `exciting` vaccine, which is in development, could help control symptoms of grass pollen hay fever with injections over the course of a few months, scientists claim. The prototype vaccine is also designed to tackle grass pollen hay fever, also known as summer hay fever, `The Telegraph` reported. The jab uses the same basic science as an existing vaccine which requires a course of injections lasting several years and benefits only around 1,000 people a year. However, the new vaccine has potential to be far cheaper and convenient after immunologists worked out that injecting closer to the skin`s surface was far more effective than the current method.
