Dr Mercola, a MD, states on an email I received from a friend:
"A study published in the Lancet just found that influenza vaccination was NOT associated with a reduced risk of pneumonia in older people. Why is this important? Because 35,000 of the 36,000 "flu" deaths the government claims happen each year are actually caused by diseases like pneumonia, and NOT the flu
· Giving young children flu shots appeared to have no impact on flu-related doctor visits or hospitalizations during two recent flu seasons, according to a study published in the October issue of the Archives of Pediatric & Adolescent Medicine. This link opens up Dr Mercola's website.
· The flu vaccine is no more effective for children than a placebo, according to a large-scale, systematic review of 51 studies, published in the Cochrane Database of Systematic Reviews. Dr Mercola is plagiarizing this information. See the actual study abstract below.
· NO studies have conclusively proven that flu shots prevent flu-related deaths among the elderly. For this statement, Dr Mercola is quoting his own website.
· A study published in the Lancet just found that influenza vaccination was NOT associated with a reduced risk of pneumonia in older people. Why is this important? Because 35,000 of the 36,000 "flu" deaths the government claims happen each year are actually caused by diseases like pneumonia, and NOT the flu. Again, DrMercola is plagiarizing the information, as pneumonia is a consequence of influenza, as the medical profession knows.
· Research published in the American Journal of Respiratory and Critical Care Medicine also confirms that there has been no decrease in deaths from influenza and pneumonia, despite the fact that vaccination coverage among the elderly has increased from 15 percent in 1980 to 65 percent now. Please read the original study abstract below. The red highlights are mine.
For even more information, studies and statistics about the flu shot, please review this previous article."

Vaccines for preventing influenza in healthy children.Smith S, Demicheli V, Di Pietrantonj C, Harnden AR, Jefferson T, Matheson NJ, Rivetti A.
Oxford University, Institute of Health Sciences, Old Road Headington, Oxford, UK, OX3 7LF. sue.smith@public-health.oxford.ac.uk BACKGROUND: In children and adults the consequences of influenza are mainly absences from school and work, however the risk of complications is greatest in children and people over 65 years old. OBJECTIVES: To appraise all comparative studies evaluating the effects of influenza vaccines in healthy children; assess vaccine efficacy (prevention of confirmed influenza) and effectiveness (prevention of influenza-like illness) and document adverse events associated with receiving influenza vaccines. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 1, 2005); OLD MEDLINE (1966 to 1969); MEDLINE (1969 to December 2004); EMBASE (1974 to December 2004); Biological Abstracts (1969 to December 2004); and Science Citation Index (1974 to December 2004). We wrote to vaccine manufacturers and a number of corresponding authors of studies in the review. SELECTION CRITERIA: Any randomised controlled trials (RCTs), cohort and case-control studies of any influenza vaccine in healthy children under 16 years old. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. MAIN RESULTS: Fifty-one studies involving 263,987 children were included. Seventeen papers were translated from Russian. Fourteen RCTs and 11 cohort studies were included in the analysis of vaccine efficacy and effectiveness. From RCTs, live vaccines showed an efficacy of 79% (95% confidence interval (CI) 48% to 92%) and an effectiveness of 33% (95% CI 28% to 38%) in children older than two years compared with placebo or no intervention. Inactivated vaccines had a lower efficacy of 59% (95% CI 41% to 71%) than live vaccines but similar effectiveness: 36% (95% CI 24% to 46%). In children under two, the efficacy of inactivated vaccine was similar to placebo. Thirty-four reports containing safety outcomes were included, 22 including live vaccines, 8 inactivated vaccines and 4 both types. The most commonly presented short-term outcomes were temperature and local reactions. The variability in design of studies and presentation of data was such that meta-analysis of safety outcome data was not feasible. AUTHORS' CONCLUSIONS: Influenza vaccines are efficacious in children older than two years but little evidence is available for children under two. There was a marked difference between vaccine efficacy and effectiveness. That no safety comparisons could be carried out emphasizes the need for standardisation of methods and presentation of vaccine safety data in future studies. It was surprising to find only one study of inactivated vaccine in children under two years, given recent recommendations to vaccinate healthy children from six months old in the USA and Canada. If immunisation in children is to be recommended as public-health policy, large-scale studies assessing important outcomes and directly comparing vaccine types are urgently required.

Mortality reduction with influenza vaccine in patients with pneumonia outside "flu" season: pleiotropic benefits or residual confounding? Eurich DT, Marrie TJ, Johnstone J, Majumdar SR. Department of Public Health Sciences, School of Public Health, University of Alberta, 13-103 Clinical Sciences Bldg., Edmonton, AB, T6G 2G3 Canada. deurich@ualberta.ca Comment in: Am J Respir Crit Care Med. 2008 Sep 1;178(5):439-40.
RATIONALE: Observational studies suggest a 50% mortality reduction for older patients receiving influenza vaccination; some deem this magnitude of benefit implausible and invoke confounding by the "healthy user effect" as an alternate explanation. OBJECTIVES: To evaluate unrecognized confounding by hypothesizing the presence of a 50% mortality reduction with vaccination for patients with pneumonia outside of influenza season. METHODS: Clinical, laboratory, and functional data were prospectively collected on 1,813 adults with community-acquired pneumonia admitted to six hospitals outside of influenza season in the Capital Health region (AB, Canada). Vaccination status was ascertained by interview and chart review. Outcome was in-hospital mortality. Influenza-vaccinated patients were matched to a nonvaccinated control using propensity scores, and then multivariable regression was used to determine the independent association between vaccination and mortality. MEASUREMENTS AND MAIN RESULTS: The cohort consisted of 352 vaccine recipients and 352 matched control subjects. Most (85%) patients were 65 years or older, 29% had severe pneumonia, and 12% died. Influenza vaccination was associated with a 51% mortality reduction (28 of 352 [8%] died vs. 53 of 352 [15%] control subjects; unadjusted odds ratio [OR], 0.49; 95% confidence interval [CI], 0.30-0.79; P = 0.004) outside influenza season. Adjustment for age, sex, and comorbidities did not alter these findings (adjusted OR, 0.45; 95% CI, 0.27-0.76). More complete adjustment for confounding (e.g., functional and socioeconomic status) markedly attenuated these benefits and their statistical significance (adjusted OR, 0.81; 95% CI, 0.35-1.85; P = 0.61). CONCLUSIONS: The 51% reduction in mortality with vaccination initially observed in patients with pneumonia who did not have influenza was most likely a result of confounding. Previous observational studies may have overestimated mortality benefits of influenza vaccination.
