Influenza, Flu Shots, and Vitamin D





Dear Dr. Cannell:





Will the Mexican flu come back again this year? Should I get a flu shot or just take vitamin D?





Sincerely,

Cynthia, Nebraska











Dear Cynthia:





I don't know and I don't know. However, I am beginning to believe that vitamin D is at least as protective as flu shots, although such a head to head comparison has never been done. The reason I say that is two-fold:







Several randomized controlled trials of vitamin D have suggested that the right dose of D may be as protective as most studies of the effectiveness of flu vaccines.

Mass vaccination of our elderly has failed to reduce the rate of influenza hospitalization or death rate among the elderly.





However, I suspect that as flu vaccinations rates in the elderly went up in the last 30 years, acquired immune deficiency syndrome due to vitamin D deficiency also went up and the two canceled each other out.
