Fingerprint sensors are reportedly helping reduce vaccine waste in developing countries by allowing healthcare workers to immediately consult a patientâ€™s vaccination record.
According to biometric authentication company Lumidigm, many patients in developing countries are being re-immunized unnecessarily while other children are completely missed. This means that finite supplies of vaccine go to waste, adding unnecessary costs to vaccination programmes and endangering the lives of children who donâ€™t receive the vaccine.
With the biometric vaccine record system, adults and children can be identified in the vaccine registry using fingerprint sensors, allowing healthcare workers to see immediately what doses are and arenâ€™t needed.
Mark Thomas, executive director of VaxTrac, said: â€œWith our VaxTrac system leveraging Lumidigm fingerprint sensors, we have been able to improve immunization tracking which allows us to reduce waste so that we can vaccinate more people and save lives.â€
The key to the new fingerprint sensors is that they scan the fingerprint at a deeper level in the skin. â€œSince the skin of children, especially young children, can be very malleable, we knew from experience that conventional biometric technologies that need a finger pressed against the device do not workâ€, said Thomas. â€œThe ability that Lumidigm offers to pull fingerprint images from deeper layers produces images less susceptible to distortion and allows us to track vaccinations accurately.â€
The fingerprint sensors and biometric vaccine registry have been used this year in Kenya, Uganda, Benin and Zambia.
