Abstract: The emergency need for vaccination during the COVID-19 pandemic has reminded the significance of having an efficient vaccine supply chain network. The fact that the COVID-19 vaccine (C19V) is a newly added member of the vaccine basket highlights the importance of redesigning the current vaccine supply chains, particularly in countries with some existing vaccine manufacturers. In addition, the economic and social drawbacks of the COVID-19 pandemic have led to the vagueness of some factors, such as birth rate and childhood vaccine demand. Hence, this paper proposes a fuzzy multi-period mixed-integer mathematical model to modify the current vaccine supply chain to deal with new challenges after the COVID-19 pandemic. The proposed model is solved using the CPLEX solver in a case study from Iran. Results show that Iran needs four new vaccine manufacturers and eight distribution centres to handle the vaccine transmission between factories and all customers in the new vaccine supply chain network.
