Common Questions. Clear Answers.

Physicians “push” vaccines because they are getting kickbacks from pharmaceutical companies and insurers.
Physicians administer vaccines based on the evidence-based vaccination schedules, recommended by organizations like the American Academy of Pediatrics.

Some insurers may offer financial incentives to physicians for reducing health care costs; however, the incentives are based on physicians performing a comprehensive list of preventive services aimed at preventing illnesses and keeping patients healthy and out of the hospital and improving overall patient outcomes.

In addition, the Physician Payments Sunshine Act requires applicable manufacturers of drugs, devices, biologicals, or medical supplies to annually report to the U.S. Department of Health and Human Services certain payments or other transfers of value made to physicians and teaching hospitals. This data is available to the public.
There is a link between vaccines and autism.

Scientific studies and reviews continue to show no relationship between vaccines and autism.

Vaccines contain harmful ingredients and they aren't adequately researched.

Any substance can be harmful in significantly high doses, even water. Vaccines go through a rigorous approval process with the Food and Drug Administration (FDA) just as over-the-counter and prescription drugs do.

The FDA requires that vaccines undergo an extensive development program in the laboratory, as well as in animal studies and human clinical trials, to determine their safety and effectiveness. Highly trained FDA scientists and clinicians carefully evaluate all of the information and make a determination whether to license (approve) a vaccine before it can be used in the U.S. Prior to licensure, as part of the FDA’s evaluation, it takes all of the ingredients of a vaccine into account, including the active ingredients as well as other substances. After the FDA approves a vaccine, it continuously monitors its safety.

There have been concerns raised about some vaccine ingredients such as aluminum. However, using this as an example, aluminum is also found in drinking water, fruits and vegetables, flour, cereals, nuts, dairy products, honey, antacids, buffered aspirin, antiperspirants, and more.

The number of recommended vaccines has tripled since the mid-80s.

The American Academy of Pediatrics currently recommends 15 vaccines for children birth through age 18. Of those, eight were approved between 1987 and 2006. From 1995 to 2010 four new vaccines were added with four updates to previously recommended vaccines. Annual updates to both the childhood and adult immunization schedules offer guidance to health care providers.

Herd immunity isn’t a real thing.

Herd immunity, also known as community immunity, is very real. It protects everyone, but is especially important because some people can’t get vaccinated against certain diseases — such as infants and those with weakened or failing immune systems. If a large portion of the population is immune to those diseases, ideally through vaccination, it is unlikely those diseases can spread.

You can get the disease from the vaccine.

A vaccine that causes someone to get a complete case of the disease is extremely unlikely. Most vaccines are inactivated, meaning they contain dead germs but no live virus. Therefore, it is impossible to contract the disease. A few vaccines (chickenpox for example) contain weakened forms or small pieces of germs. Others contain generic instructions for immune cells to identify germs. Since vaccines do not contain germs in disease-causing forms, they will not give you the disease they are designed to prevent.

Vaccine preventable diseases have been virtually eliminated.

Vaccine preventable diseases have been virtually eliminated. Some vaccine-preventable diseases, like pertussis (whooping cough) and chickenpox, are still present in the US. The main reason that there are so few cases of the other vaccine-preventable diseases in the US is due to vaccines. People becoming vaccinated helped to stop the spread of disease. However, vaccine preventable diseases are still quite prevalent in other countries. Travelers can unknowingly bring these diseases into the US, and if the community is unprotected, the diseases could quickly spread causing outbreaks or epidemics. The relatively few cases that the US may currently have could very quickly become tens or hundreds of thousands of cases without the protection given by vaccines. With adequate vaccination rates, most of these types of outbreaks can be prevented. But if vaccination rates drop, “imported” cases of preventable diseases can begin to spread again.
