You’ve probably noticed the push from doctors every year for people to get the flu shot. This is a very bad idea. Flu vaccines contain a number of suspect and downright dangerous ingredients. There is also very little evidence that they actually work. In fact, in 2010, PLoS Medicine published an analysis of Canadian epidemiological studies suggesting that people, who had received a seasonal influenza vaccine the year before the 2009 H1N1 swine flu pandemic, actually had an increased risk of being infected with the pandemic swine flu. Looks like the flu shot does more harm than good While everyone who gets a flu shot is at risk for negative side effects, the elderly and children are the most at risk, since they are the most immune-compromised among us.
