During the second wave of the COVID-19 pandemic in India, the number of infected cases spiked exponentially, highlighting the urgent need for universal vaccination as the ultimate solution. While vaccines were manufactured at accelerated speeds, administering them to the eligible adult population across the country was an insurmountable challenge. Most COVID-19 vaccines in India require cold storage, and any lapse in temperature control during transport or storage can compromise their potency. Given India’s inadequate infrastructure to meet these requirements, there was an urgent need to strengthen India’s cold chain management to achieve the national goal of universal vaccine coverage.
