There are about 40 million good reasons to become a Vaccines for Children provider.
40 million—that’s how many kids got their shots who otherwise would not have been vaccinated due to inability to pay. And that’s just in 2010 alone.
The federally funded program came to life in 1994 on the heels of a 1989-1991 measles epidemic that involved thousands of cases and hundreds of deaths. A subsequent study found that more than half the children who contracted the measles during that outbreak had not been immunized.
VFC provides routine vaccines to all states and territories for distribution at no cost to any healthcare provider authorized to prescribe vaccines in their respective jurisdictions.
The program is good for providers because it keeps patients coming through the doors – charges for office visits and to administer the vaccines are allowed – and it’s good for kids because they get their shots.
The CDC has specific recommendations and requirements, however, on how VFC providers should store and handle vaccines.
First, the storage unit itself. CDC recommendations include:
Once the proper cold storage unit is in play, consideration turns to monitoring its temperature and maintaining the appropriate vaccine temperature log.
On those issues, the CDC recommends:
The results of storing vaccines in subpar or inappropriate refrigerators and freezers lacking reliable monitoring equipment are not hard to fathom. At best, a provider will lose a significant vaccine inventory; at the other end of the scale are children who are given ineffective vaccines.
While the implications might be obvious, a 2012 study using a CDC data sample of 45 providers with the highest volume of orders in 2010 found serious shortcomings.
Vaccines stored by a full 76 percent of the providers surveyed were exposed to “inappropriate temperatures for at least five cumulative hours” during the two-week inspection period. Further, the selected providers did not generally meet vaccine management requirements or maintain the required documentation.
Sonicu's patented, glycol-buffered wireless temperature sensors, wireless temperature monitoring system, SNAP Calibration program, and SoniCloud cloud-based software meet or exceed all CDC requirements for the VFC program and provide a seamless temperature monitoring package for any VFC provider.

The Importance of Proper Vaccine Storage
Before delving into the specific risks associated with old refrigerators, it is essential to understand why proper vaccine storage is so important.
Vaccines are sensitive biological products that contain live or inactivated microorganisms, antigens, or adjuvants.
Exposure to inappropriate temperatures, such as freezing or excessive heat, can harm vaccine components, reduce potency, and render vaccines ineffective. The threat is so grave that the federal government made temperature monitoring mandatory during the speed rollout of the COVID-19 vaccine.
You may recall stories about people rushing to a nearby hospital or clinic to distribute the COVID-19 vaccine when officials announced vaccines would have to be discarded if not used in hours because they had been removed from their cold storage.
Moreover, temperature fluctuations can accelerate degradation and compromise vaccine stability, posing serious public health risks.
Sonicu helps scores of county health departments responsible for the local distribution of immunizations with our simple and affordable vaccine monitoring kit that meets the standards set by the Centers for Disease Control and is verified by state health departments nationally.
The Role of Refrigerators in Vaccine Storage
Refrigeration is the primary method used to maintain the potency and stability of vaccines from the time of manufacture to administration.
According to the Centers for Disease Control and Prevention (CDC), most vaccines should be stored at temperatures between 2°C and 8°C (36°F and 46°F) to ensure optimal efficacy.
Refrigerators and freezers equipped with temperature monitoring devices, such as thermometers and data loggers, are essential for maintaining the cold chain and preventing temperature excursions that can compromise vaccine quality.
Sonicu even offers affordable mobile sensors that can track temperatures while vaccines and other medicines are en route from a distribution site to retail locations, and then reconnect with a central hub when the trucks return to the distribution center, syncing the monitoring data to deliver a comprehensive temperature tracking system crucial to safe drug and vaccine delivery.
Risks Associated with Old Refrigerators
Temperature Inaccuracy and Fluctuations:
Old refrigerators may lack accurate temperature control mechanisms and insulation, leading to temperature fluctuations and inconsistent cooling.
Studies have shown that older refrigerators often fail to maintain stable temperatures within the recommended range, increasing the risk of vaccine spoilage.
Without reliable temperature monitoring, vaccines stored in old refrigerators are vulnerable to exposure to sub-optimal temperatures, compromising their potency and effectiveness.
Inadequate Air Circulation and Humidity Control:
Old refrigerators may suffer from poor air circulation and humidity control, creating microenvironments that are conducive to bacterial growth and moisture accumulation.
Condensation and humidity can accelerate vaccine degradation and promote microbial contamination, posing contamination risks.
Additionally, inadequate ventilation can lead to uneven cooling and temperature differentials within the refrigerator, further exacerbating the risk of temperature excursions and vaccine spoilage.
Lack of Compliance with Regulatory Standards:
Old refrigerators may not meet current regulatory standards and guidelines for vaccine storage and cold chain management.
Regulatory agencies, such as the CDC and the World Health Organization (WHO), provide detailed recommendations for vaccine storage equipment, including specifications for temperature monitoring devices, storage capacity, and maintenance procedures.
However, older refrigerators may not meet these requirements, making them unsuitable for storing vaccines safely. A remote, wireless temperature monitoring system like Sonicu is the ideal solution to help compliance professionals stay aware of their refrigerator’s status and be able to replace an aging system before its failure threatens vaccine safety.
Limited Capacity and Accessibility:
Old refrigerators may have limited storage capacity and inadequate shelving arrangements, making it challenging to organize and access vaccines efficiently.
Inadequate space and overcrowding can impede air circulation and temperature uniformity, increasing the risk of temperature excursions and cross-contamination.
Moreover, older refrigerators may lack modern features, such as adjustable shelves and compartments, which are essential for optimizing storage conditions and accommodating different vaccine vial sizes.
