Is vaccine shedding harmful?

There is risk for someone who has a weak immune system. The risk is very small when coming into contact with someone who had been vaccinated with a live weakened vaccine. The higher risk would be immunizing a person who is highly immunocompromised (very weak immune system). This is why recommendations for these persons typically include holding live vaccines until their immune system function improves.

Are the ingredients in immunizations dangerous?

No. Immunizations and their ingredients are also studied extensively before licensure to ensure their safety. Certain ingredients are used to maintain the safety and sterility of a vaccines, and to increase the immune response. The below link to the Vaccine Education Center at The Children’s Hospital of Philadelphia breaks down a lot of this information. The ingredients in immunizations are included to create a stronger immunize response and make them work better. The ingredients do not cause diseases.

Are the side effects of immunizations worse than the diseases they prevent?

Vaccines are studied extensively and continuously and are very safe, while the diseases they prevent can cause serious injuries and even death. The Vaccine Safety Datalink (VSD) founded in 1990 continuously monitors the safety of vaccines and conducts studies about rare and serious adverse events following immunization. Any new vaccines recommended for use in the Unites States are also monitored by the VSD for safety.
