The first vaccine was developed during the late 18th century. This smallpox vaccine is estimated to have saved hundreds of millions of lives since its development, and rendered the infection completely eradicated, with the last case reported in 1977.
While there is some controversy surrounding vaccines and their reported risks these days, the fact is that vaccines are safe, vaccines are necessary, and vaccines work. If you have questions about vaccinating your child, here are some crucial facts to consider.
Vaccines contain antigens, which are substances that trigger an immune system response. Antigens can consist of diluted bacterial toxins, weakened/dead forms of germs (including bacteria and viruses), and small particles taken from specific parts of germs. By responding to these antigens, your body will learn how to defend against new germs, which will prevent you from getting sick and/or experiencing serious symptoms.
Your body does build immunity after contracting an illness, but symptoms can become quite serious and may require advanced medical treatment. You will also be able to pass the illness to others. With vaccines, there is no risk of serious symptoms, and you will not be able to pass along germs.
Like all other medications, vaccines are associated with some side effects. For the vast majority of children who receive vaccines and experience side effects, health problems are mild and resolve quickly on their own.
There can be a chance of more serious reactions to vaccines, but these are extremely rare. Additionally, doctors will not recommend vaccines to children if there are major risks involved (such as an established allergy to an ingredient within the vaccine).
Some people believe that as long as most of the public is vaccinated, it should not matter whether they or their children are protected. However, consider that vaccines are most effective when the entire community participates.
Also, while you or your child may experience mild symptoms when ill, vulnerable people can become extremely sick when exposed to common germs. In some cases, infections can be life-threatening. When you choose not to vaccinate, you are directly putting others at risk.
