Treat the flu patients with massive doses of vitamin C, and they'll recover, with strengthened immune systems to show for it - search for Allan Smith New Zealand Vitamin C to find the TV news coverage of just such a case. Meanwhile, the Cochrane Collaboration in 2010 found the flu vaccine right at 1% effective at actually preventing the flu, while the CDC in their database shows 1,015 flu vaccine deaths, 2,022 life threatening reactions, 1,611 permanent disabilities and thousands of resultant hospitalizations and emergency room visits - and it's well accepted that actual serious adverse vaccine reactions are sorely underreported. The flu virus doesn't fly south for the summer. It's always with us, but our D3 levels, triggered by sunlight, are diminished during the winter. Vitamin D3 supplementation provides excellent protection during the winter months, with no side effects. Educate. You can't eliminate risk from life, but the risk of damage from vaccines far outweighs the risk of damage from disease.
