A multi-million dollar trial has been launched to determine if a pertussis vaccine is linked to the dramatic increase in the number of children with food allergies.
The number of Australian children with food allergies has exploded since the late 1990s – around the same time a new pertussis vaccine was introduced.
Research in Melbourne and Perth will test the theory that the two babies are linked to 3,000 babies in the $ 4 million clinical trial.

Associate Professor Tom Snelling, a senior scientist at Curtin University and Telethon Kids Institute, told the Herald Sun that when infants received the old vaccine, very few people had a typical immune response in their blood that would be typical those who later develop allergies.
He added that a dose of the old vaccine could be enough to form the immune system against allergies.
The old vaccine was replaced in 1999 after the announcement of minor side effects, including fever and needle-stick pain.
Since the change, the number of young children suffering from anaphylactic reactions to food has increased steadily.

"The immune system needs to mature quickly in the first few months of life after birth, so it's better for protection against infection," Snelling said.
Facts on food allergies:
The number of children suffering from food allergy or immune-related disorder has increased dramatically over the past 10 years.
Symptoms of food allergy may be mild, such as hives or swelling, or severe breathing causing effects

"This normally happens by being exposed to infections.
"Because we live in much cleaner environments, children are no longer exposed to infections like before, so maybe that's why we see a lot more allergies."
The project funded by the National Health and Medical Research Council will involve babies from Melbourne, Sydney and Adelaide.
When children are 18 months old, researchers will determine if they have symptoms of food allergy.
Researchers are currently recruiting children to participate in the trial.
