Why Flu Shots Cause More Harm than Good Many people follow their doctors’ advice to get a flu shot without thinking twice, but do they even know what’s being injected into their body or the side effects it can cause? As with most medications and vaccines that physicians push, they rarely ever mention the harmful effects they can cause. Flu vaccines contain toxic ingredients such as heavy metals and mercury. This past year, genetically modified organisms (GMO’s) have also been added to list of harmful ingredients in flu shots. Flu vaccines only prevent the flu in 1.5% of adults. Flu shots also come with serious health risks including: immunosuppression, increased risk of Alzheimer’s disease, neurological disorders, autoimmune diseases, seizures, miscarriages, and death.
