By all indications the H1N1 Flu is already beginning to pay a return visit to the Northern Hemisphere. In the USA the Government is promising that a vaccine will be ready in time to head off the H1N1 and protect us from the consequences of this disease this fall of 2009. Due to the short time required to prepare the new, H1N1 vaccine we do not know how well it will work in the general public. The second issue that has been raised concerns the availability of and accessibility to the vaccine by the general public. Putting all our hope on this new, H1N1 vaccine to provide protection from the H1N1 flu is like putting all our health protection in one basket. Common sense says that we should have a layered defense in place that will preempt the H1N1 flu. The key to such a layered defense will be to take steps that will strengthen a weakened immune system.

Taking the path to boost immune system has strong support from diverse groups that are concerned about preventing the spread of the H1N1 flu. An agency of the Canadian Government is studying the role of vitamin D in preventing the onset or mitigating the severity of the flu infection. Numerous studies have shown that a deficiency of vitamin D is linked to influenza infections. The Harvard Medical School, that normally recommends getting vitamins through food, makes an exception for supplementing with vitamin D. The good news is that the vitamin D supplements that duplicate the form D3 made by our bodies in sunlight are very inexpensive. The D3 form that is more readily absorbed by our bodies is preferred over the less potent form D2. Together with eating a healthy diet and getting enough sleep, supplementing with vitamin D3 will support a layered defense against infection by the H1N1 flu.
