What every person with allergy fear is the upcoming change in season. For many, it is the start of headaches, never ending runny noses and itchy eyes throughout the season that plagues in each individual they their own unique allergies.
An immunologist from McMaster University in Hamilton, Canada named Mark Larche has been developing a vaccine that will be more quick and safe than current therapies. This will be the next-generation allergy shot.
Doctors do know and realize that current forms of therapy requires the patient to take injections regularly for three times a week up to seven months and could continue up to 5 years or more. The injections effectiveness is a risky approach by increasing the tiny amount of what the individual is allergic to for each injection. The risk is serious, it could range from swelling to a anaphylactic shock. all the from the allergic reaction of the current therapies for allergies.
The new and improved shot in the works will use only pieces of what the person is allergic to and injected into the body, but just enough that the body will not cause any allergic reaction. Administering of the new vaccine would be one shot for every four months.
Larche has been testing his first trial runs with people who are allergic to ragweed and cat because 20% and 10% of Americans are affected by these two respectively.
Trials included 350 people for the cat vaccine and planning to test several hundred more people in the later months of 2011. Also, 300 allergy sufferers had ragweed version. The rescipients were held inside a chamber with circulating allergen and the results showed that approximately half of the people had no and little response.
