Why Does the Vaccine Cold Chain Matter in 2025?
Respuesta directa
Maintaining a robust vaccine cold chain is vital because many vaccines lose potency when exposed to temperatures outside their specified range. Most routine vaccines require refrigerated storage between +2 °C y +8 °C, while frozen vaccines such as varicella or zoster must stay between –50 °C and –15 °C. Cutting edge therapies like mRNA boosters and gene therapies demand ultra cold storage (–80 °C a –60 °C). Without consistent temperature control, vaccine ingredients degrade quickly, leading to wasted doses and compromised immunity.
Explicación expandida
En 2024 the World Health Organization (OMS) estimated that approximately half of vaccines are wasted globally due to exposure outside the recommended temperature range. This statistic underscores how easily a temperature excursion can ruin valuable doses, costing billions of dollars and undermining public trust. Maintaining a proper cold chain protects patients, reduces waste and supports vaccination campaigns. According to the CDC’s Vaccine Storage and Handling Toolkit, refrigerators should maintain 2 °C-8 °C, congeladores –50 °C a –15 °C, y congeladores ultrafríos –90 °C a –60 °C. Devices with digital data loggers are recommended to track temperature continuously and provide alarms for out of range events. Regular monitoring and calibration help ensure vaccines remain potent from manufacturer to patient.
As the number of vaccines grows—ranging from COVID 19 boosters and malaria vaccines to personalised gene therapies—so do storage complexity and risk. The AAAHC reminds providers that live attenuated vaccines often require frozen conditions (–15 °C to –50 °C) while most others must stay refrigerated. Because mistakes can lead to revaccination or disease outbreaks, 2025’s cold chain trends emphasize real time monitoring, staff training and emergency planning.
