Context: Vaccination as prevention to hold back the spread of COVID-19 is important since it is the most concerning health issue in the last decade. Inactivated vaccine platforms considered safer, especially for elderly and comorbid patients. Comorbidities especially Tuberculosis and Hepatitis B, has a major impact to COVID-19 infections and vaccination. To evaluate infections or vaccine response IFN-γ and CD4+ are important. IFN-γ has a role in antiviral innate response, including initiation of other cytokines, increasing MHC expression, increasing presentation of macrophage, and increasing presentation of antigen to T cell Naïve. CD4+ is associated with humoral immune response. Cynomolgus Monkey or known as Macaca fascicularis. Specifying to comorbid patients, adult Macaca fascicularis that are detected to have hepatitis B and Tuberculosis (TBC) by PCR were treated as a comorbid group. Adult Macaca fascicularis that used in this research have range from 6 to 9 years old. This study was analysed with SPSS 26 general linear model repeated measures analysis with p<0.05 Objectives: To evaluate IFN-γ and CD4+ response of vaccination Result: The result of this study showed significant (p < 0.05) increase in IFN-γ and CD4+ evaluation in both comorbid and adult groups. The elevating concentration and percentage could be the sign of induced humoral and adaptive immune system in the body. Conclusion: SARS-CoV-2 inactivated vaccine candidate that used in this study can increase the number of IFN-γ concentration as well as percentage of CD4+ in adult and comorbid groups of Cynomolgus Macaques.
