Vaccine Ingredients & Excipients Are vaccine ingredients, adjuvants, and preservatives safe? An excipient is an inactive substance that serves as the vehicle or medium for a drug or other active substance. Excipients are things like coloring agents, preservatives, and fillers. While you can refer to package inserts for some detail on ingredients and possible contraindications, the CDC's list of Vaccine Excipients by Vaccine Name will detail the amount of ingredients per dose and its purpose. Please refer to VaccineSafety.edu for the most up-to-date materials on vaccine excipients. Here are a few concerning ingredients we saw in the most recent list, updated in December 2024: Formaldehyde Glutaraldehyde Polysorbate 80 Thimerosal DNA Some of these same chemicals are on the California's Proposition 65 list of chemicals that cause cancer. The list of "Vaccine Excipients by Vaccine Name" is from the CDC in partnership VaccineSafety.edu Download the Vaccine Excipient list (pdf) Another compelling vaccine ingredient resource is this 2024 list from the Health Freedom Institute , that color codes various vaccine ingredients of concern. Preservatives Prevent the growth of bacteria or fungus in vaccines. Disinfectants These chemicals are used to inactivate the toxins and viruses in the vaccine. Antibiotics Used in production to prevent bacterial contamination during manufacturing. Fertilizer Chemicals used in fertilizers are also found in vaccines. They are used as “stabilizers” and preservatives, and as part of a process to determine effectiveness. Aborted Fetal Cells Cell lines are used to grow vaccines. It is possible that DNA from the “host” line remains in the final vaccine. Could human DNA in vaccines cause cancer, brain damage? Former pharmaceutical senior scientist, Hellen Ratajczak, explains that when DNA incorporates into a host DNA, it can result in ongoing inflammation that continues throughout the life of an individual. Read the article on CBS News Vaccines that use or contain aborted fetal cells Aborted fetal cells are sometimes used in the testing of vaccines while other manufacturers use fetal cells in the development process. When used in the development process, residual biological components from the fetal cells can be assimilated into the vaccines, including cell proteins and measurable portions of fetal DNA. To our current knowledge (Nov 2025), there are no COVID-19 vaccines being tested or manufactured that do not use fetal cell lines from aborted infants.

Vaccine Info Statements vs. Package Inserts Federal law requires that every person, regardless of age, is given a Vaccine Information Statement for a selection of vaccines prior to vaccination. A complete list of all available VIS can be found at https://www.immunize.org/vaccines/vis/about-vis Originally, a VIS was intended to fulfill the requirements of the National Childhood Vaccine Injury Act of 1986 . Based on a 1993 amendment , it was determined that a VIS must provide: A concise description of the vaccine benefits A concise description of the associated risks A statement of the availability of the National Vaccine Injury Compensation Program Other relevant information as may be determined by the Secretary There is also information on each VIS about adverse reactions, and how they should be reported to the Vaccine Adverse Event Reporting System (VAERS) . Get more information about VIS from the CDC https://www.cdc.gov/vaccines/hcp/about-vis/index.html Thie following is a VIS instruction sheet for healthcare providers.

Explore all VIS available on immunize.org We often hear from injured parties as well as healthcare providers that they were "unaware" of any type of injury reporting system associated with vaccines. Bearing that in mind, we must ask how many healthcare providers adhere to Federal Law to provide a VIS to vaccine recipients prior to vaccination, and is there any consequence for this breach in trust? Unlike the simplified VIS, the package insert is a highly detailed multi-page document with important information on dosing, contraindications, safety trials, and post-marketing observations if available. PDFs of package inserts are found at https://www.immunize.org/official-guidance/fda/pkg-inserts Even though package inserts are written in a technical language and are lengthy and can be difficult to understand, it is a good idea to look through them anyway because they list important information about the drug. Key areas to review include: Vaccine administration and storage instructions Contraindications relative to your health, or prior vaccine reactions Warnings and precautions What adverse reactions may occur What safety studies were done and for how long A sample to explore... This is the 28-page package insert for the ProQuad® Measles, Mumps, Rubella and Varicella Virus Vaccine Live Suspension for intramuscular or subcutaneous injection. Compare this to the 2-page VIS sample above. Download the MMRV package insert (pdf) Before You Vaccinate Prior to the appointment, prepare any questions you may have for your healthcare provider about ingredients , efficacy, and storage requirements of your vaccine to ensure they were met (some vaccines need to be refrigerated). At the appointment , your provider is required by Federal Law to give you a Vaccine Information Sheet (VIS) prior to administering the vaccine. Review the VIS with your provider. If the vaccine is coming from a multi-dose vial, ask your provider if the bottle has been properly shaken prior to each draw, and which recipient or dose number you would be considered. Before your appointment concludes , document the following additional details for yourself. The lot number of your vaccine Dose/recipient number (if a multi-dose vial) Manufacturer name (brand) Vaccine country of origin (e.g., U.S., China) Expiration date You might also be interested in: Vaccination Schedules & Rates Vaccine Ingredients & Excipient List 1,000+ Peer-reviewed Studies on Vaccines Recommended Books, Videos and Websites
