Health ministry says return of Covid-19 vaccines to COVAX in order The South Sudan ministry of health has said the return of Covid-19 vaccines to the COVAX facility, the global initiative for equitable access of vaccines, should not cause concern as it is based on the country's absorption capacity. The undersecretary of the health ministry, Mayen Machut Achiek, explained in an interview with Radio Tamazuj on Wednesday that the move was compelled by the realization that the country cannot administer the vaccines before their expiry date. “With the African countries that are having financial problems with storing the vaccine, what the COVAX facility has done is they will take from you the quantity that you are unlikely to deploy before the expiring date,” Machut explained. “So instead of (the vaccine) expiring in your cold chain, they will take it and put it on the platform. Now when it is still on the platform, a country will pop up and say it will be able to deploy it in three weeks, and therefore, all of us win.”
