Solar technologies can speed up vaccine rollout in Africa. Here’s how.

There’s hope that some industrialised countries will achieve near-universal vaccination against COVID-19 in the coming months. Yet the effort to vaccinate even the most essential workers in developing countries has only just begun. By current estimates, achieving herd immunity (to current strains) will require at least 75% of the world’s population to be vaccinated. Some developing countries haven’t reached that level of coverage even for common vaccine-preventable diseases like measles and polio. But the success of national distribution efforts depends on a functional cold chain. This is an uninterrupted system of storage, transport and delivery of vaccines at low temperatures all the way from national warehouses to local clinics and into the arms of people.
