It is perhaps inevitable, given the serious impact of Covid-19 on so many people and places, that some individual countries will want to be first in line to secure a stock of vaccines for themselves.
This is, however, only the first step. When found, ensuring that everyone will be able to benefit from it quickly and at an affordable cost is the main challenge governments and the international community have to address.
The first important action will be to ensure sufficient global supply for these products. This includes massive production of the vaccine constituents but also of the dispensing devices, such as syringes or intranasal sprays. Companies and Governments are already engaging in agreements with manufacturers and device producers, to ensure they scale-up their capacities to respond to the massive surge in demand they will face when the first candidates will be getting close to marketing authorization.
