“A recent study published in The Lancet: Infectious Diseases showed that for every 100 people who are vaccinated, only 1.5 were prevented from getting the flu”1. Furthermore, the abstract summary states “Evidence for protection in adults aged 65 years or older is lacking.”2 However, this study does suggest that influenza vaccinations show 75% efficacy over 12 years of for the age group of 6 months to 7 years.2
Note that the flu vaccine is now marketed to all population groups, and especially the elderly, and this research study shows that it basically is only effective for children under 7!! So why then is it marketed to everyone? Capitalism is why, not true health concerns!!
