 The trend of susceptible, infected and recovered of an epidemic can be mathematically analyzed if the solution of its SIR model is obtained. Various analytical and numerical methods were used by previous researchers in order to solve the model. Adomian Decomposition is one of the methods. However, several studies discovered that ADM is tedious and time consuming in solving certain kinds of problems. In this project, another method was used and compared to ADM in solving SIR model with the coverage of vaccination. The method was Differential Transformation Method (DTM). The main objective of this project is to analyse the difference between these two methods in the process of getting the final solution. It was identified that to get only one term of the polynomial solution model of SIR, ADM requires many iterations unlike DTM which only requires one iteration for each term of the polynomial solution model. However, in terms of overall polynomial model, ADM gives a higher degree of polynomial model compared to DTM for the same number of iteration.
