Dear all,

People are also living longer due to better supportive care. It would be interesting to see if the ages at which they succumb to pneumonia are constant and to compare vaccinated v unvaccinated populations, of course these are often low resource so there would have to be adjustments for that. It would also be intriguing to look at population sick days.

Best

Amy

Subject: Re: USA: What is the impact of the influenza vaccine?

Yes, it's the same trend that Peter Doshi picked up in 2008 in his eminal paper on AJPH.

Steady - no visible effect of any of the CDC policies.

But it's ecology.

Best wishes,

Tom.

-what is the use of the influenza vaccine (even mandatory for health professionals!) in the USA where almost half of the population get the vaccine (around 150 millions each year)? (http://www.cdc.gov/flu/fluvaxview/coverage-1415estimates.htm )
US Mortality Rates from Infectious Diseases Holding Steady. Pneumonia and influenza were the most common causes, accounting for 38.3% of infectious disease deaths during that time period. The mortality rate from pneumonia and the flu held steady between 1980 and 2014, at 17.1 per 100,000.
