Researchers have developed a promising new vaccine against grass pollen, which can cause hay fever, New Scientist reports. The Vienna, Austria–based firm Biomay combined pollen molecules and proteins from the hepatitis B virus (HBV). The vaccine allows the hepatitis protein to block some of the immune system’s immunoglobulin E (igE) antibodies, which can cause an excessive immune response against pollen in people who get hay fever. Researchers claim a recent trial of 180 patients proved the vaccine is safe, effective and faster than other current therapies. Successful larger trials could make the vaccine available within four years.
