Reverberating Issues with Flu Vaccine

1. What’s in the regular flu shot?
Egg proteins: including avian contaminant viruses
Gelatin: known to cause allergic reactions and anaphylaxis are usually associated with sensitivity to egg or gelatin
Polysorbate 80 (Tween80): can cause severe allergic reactions, including anaphylaxis
Formaldehyde: known carcinogen
Triton X100: a strong detergent
Sucrose: table sugar
Resin: known to cause allergic reactions
Gentamycin: an antibiotic
Thimerosal: mercury is still in multidose flu shot vials

2. Do flu shots work?
Not in babies:
In a review of more than 51 studies involving more than 294,000 children it was found there was “no evidence that injecting children 6-24 months of age with a flu shot was any more effective than placebo. In children over 2 yrs, it was only effective 33% of the time in preventing the flu. Reference: “Vaccines for preventing influenza in healthy children.” The Cochrane Database of Systematic Reviews. 2 (2008). Not in children with asthma:
for asthma.
A study 800 children with asthma, where one half were vaccinated and the other half did not receive the influenza vaccine. The two groups were compared with respect to clinic visits, emergency department (ED) visits, and hospitalizations CONCLUSION: This study failed to provide evidence that the influenza vaccine prevents pediatric asthma exacerbations.
“Effectiveness of influenza vaccine for the prevention of asthma exacerbations.” Christly, C. et al. Arch Dis Child. 2004 Aug;89(8):734-5. Not in children with asthma (2):
do not get the vaccine.”
“The inactivated flu vaccine, Flumist, does not prevent influenza-related hospitalizations in children, especially the ones with asthma. In fact, children who get the flu vaccine are more at risk for hospitalization than children who Reference: The American Thoracic Society’s 105th International Conference, May 15-20, 2009, San Diego. Not in adults:
1 (2006).
In a review of 48 reports including more than 66,000 adults, “Vaccination of healthy adults only reduced risk of influenza by 6% and reduced the number of missed work days by less than one day (0.16) days. It did not change the number of people needing to go to hospital or take time off work.” Reference: “Vaccines for preventing influenza in healthy adults.” The Cochrane Database of Systematic Reviews. Not in the Elderly:
In a review of 64 studies in 98 flu seasons, For elderly living in nursing homes, flu shots were non-significant for preventing the flu. For elderly living in the community, vaccines were not (significantly) effective against influenza, ILI or pneumonia.
