The Public Health Agency of Canada (PHAC) has confirmed that it will be investigating the role of vitamin D in protection against swine flu.
The agency started a study last year on the role of vitamin D in severe seasonal influenza, which it said it will now adapt to the H1N1 swine flu virus.
Part of the researchers’ goal is to understand whether vitamin D levels are in any way responsible for the fact that most people with seasonal influenza develop a mild illness, but a small minority go on to develop severe symptoms.
According to PHAC, results from its study will indicate the extent and nature of the role of vitamin D in severe seasonal influenza.
