About Vaccines for Children

 The Vaccines for Children (VFC) Program helps in providing vaccines to children when their parents or guardians may be unable to afford them. This ensures that children have a much better chance of getting their recommended vaccinations. The Vaccines available through the VFC Program are recommended by the Advisory Committee on Immunization and they help protect babies, young children, and adolescents from 16 diseases.

To continue to help as many children as possible, the Vaccine Cold Chain is essential to keeping vaccines potent. Too much exposure to heat, cold, or light at any step in the cold chain can damage vaccines, resulting in loss of vaccine potency. Once lost, potency cannot be restored. One of the key elements for an effective cold chain is reliable temperture monitoring equipment.




Temperature Measurement - The Drive to Meaningful Data

Think of your storage and monitoring equipment as an insurance policy to protect your patients from inadvertent administration of compromised vaccine, and your facility against costs of revaccination, replacement of expensive vaccines, and loss of patient confidence in your practice. For the best protection, your facility needs appropriate equipment that is set up correctly and maintained and repaired as needed.

"To fully ensure the safety of vaccines, the following equipment is recommended:

  • Stand-alone refrigerator(s) with enough space to accommodate your maximum inventory without crowding
  • Stand-alone freezer(s) with enough space to accommodate your maximum inventory without crowding
  • Digital data logger (DDL) with a current and valid Certificate of Calibration Testing (also known as a Report of Calibration) for each unit and at least one backup in case of a broken or malfunctioning device"


Individual Programs for each state



If you are a Vaccines for Children (VFC) provider or receive other vaccines purchased with public funds, you should consult with your state or local immunization program  to ensure you are meeting all mandatory storage and handling requirements for your state, since there may be requirements that are specific or tailored to your jurisdiction.



VFC Storage and Handling Toolkit


The Centers for Disease Control and Prevention (CDC) Vaccine Storage and Handling Toolkit  brings together best practices from Advisory Committee on Immunization Practices (ACIP) recommendations*, product information from vaccine manufacturers, and scientific studies. Implementing these best practices and recommendations will help protect your patients, safeguard your vaccine supply, and avoid the unnecessary costs.

Proper vaccine storage and handling has been an important factor in preventing and eradicating many common vaccine-preventable diseases.  Failure to store and handle vaccines properly can reduce vaccine potency, resulting in inadequate immune responses in patients and poor protection against disease. Patients can lose confidence in vaccines and providers if they have to be revaccinated because the vaccines they received may have been compromised. This toolkit provides information and resources to assist you in properly storing and handling your vaccine supply, including information on:

          • Storage and temperature monitoring equipment and setup
          • Vaccine organization and storage
          • Vaccine temperature and storage equipment monitoring
          • Vaccine inventory management, transport, and preparation
          • Emergency storage, handling, and transport
          • Vaccine storage and handling standard operating procedure development
