There is a theory that vaccines are unsafe because the cause autism, because they contain elements like mercury, or because they can cause allergic reations. Vaccines, it has been proven, do not cause autism and are in no way linked to the condition. While they do contain traces of metals like mercury, these substances are present in concentrations lower than those in our own bodies. Lastly, the allergic reactions associated with vaccines, while possible, are incredibly rare, and hospitals that provide vaccines are equipped to deal with them responsibly. It is important to stop misinformation regarding vaccines because they are necessary to keep one's self healthy, while also preventing the spread of diseases to other people.
