Discuss using different capacity planning approaches (level, aggressive, wait & see) for a vaccination programme in your country of preference (one you know very well) and suggest the best one. To answer this question, you should consider the demand uncertainty, the fact that some people are not willing to get vaccinated, the uncertainties of vaccine production and any other factor which could affect demand and supply. Embedding cultural and behavioural factors in justifying your answer is hugely encouraged. For this question, you are expected to write 800 +/- 10% words in total. We do not expect use of any source (such as journal paper, article, etc), but if you use one for your answer, you are supposed to include the reference(s) in your answer.
