Don't worry about the -80C cold chain.
The vaccine can be safely stored at -20C (in the realms of a normal freezer) for shortish periods of time, and needs to be defrosted before injection anyway.
The -80C cold chain will only be needed for the backbone of storage and delivery to hubs. A standard cold chain infrastructure will do for the spokes to vaccination points.
