A one of a kind vaccine freezer, that can store vials at ultra-low temperatures, was launched in Johannesburg on Monday.  

The prototype storage container has been developed by Renergen, a South African natural gas company.  

The container has been designed, to keep COVID-19 vaccines ultra-cold for up to 30 days,  and can store up to 6000 doses.
