It's very interestingly the same three things that we could have learnt from meningitis: modelling and predicting the outbreak—again, I'll come to coronavirus and tie this in also; vaccine supply, we ran out of measles vaccines; and contact tracing—really important parts to our coronavirus response. This was our second testing run. This was our second training run here in New Zealand. We had that information. It was our living laboratory, if you like. We had the opportunity to learn from our second infectious disease for this Government and look at those important aspects of modelling, vaccine supply, and contact tracing.
