At least seven other African countries have destroyed some 450,000 doses in all. When just 3.
But covid-19 vaccines also bring new problems, chief among them temperature control. The Pfizer/BioNTech jab requires ultra-cold storage. Though most vaccines are stable at 2°C to 8°C ,like Pfizer’s must be stored at -60°C to -80°C for most of their shelf life. Many African countries have built up their stock of medical fridges in recent years, often using solar panels to provide a reliable power supply.
Overcoming these problems will be expensive, and the WHO fears that many African countries are underestimating how much money they will need—particularly in the later stages of distribution, which will probably involve the most isolated communities. The World Bank has approved almost $1.85bn in loans and grants for African countries, but the bill for the vaccine rollout in sub-Saharan Africa could run to $12.5bn.
