The emergence in 2019 of a new coronavirus, SARS-CoV-2 (COVID-19), has made devastating and huge consequences worldwide. Apart from this, the proposed model's robustness is verified with a three-phase sensitivity analysis. The findings demonstrate that the most significant criteria considered in coronavirus vaccine selection are “duration of protection,” “effectiveness of the vaccine,” “success against the mutations,” and “logistics,” respectively, whereas the best coronavirus vaccine is AZD1222. In this work, as a case study, five coronavirus vaccines approved by the world's leading authorities are evaluated according to various criteria. Based on the group decision-making, the IF-MAIRCA framework both extracts the criteria weights and discovers the prioritization of the alternatives under uncertainty. To this end, this paper proposes a new intuitionistic fuzzy extension of MAIRCA framework, named intuitionistic fuzzy MAIRCA (IF-MAIRCA) to assess coronavirus vaccines according to some evaluation criteria. Given that this pandemic will be in our lives for a long time, it is obvious that a reliable and useful framework is needed to choose among coronavirus vaccines. To control the spread of it and to protect people, appreciable vaccine development efforts continue with increasing momentum. All over the world, the COVID-19 outbreak seriously affects life, whereas numerous people have infected and passed away.
