It is remarkable to think that since 1950 influenza has claimed more than 50,000 lives in this country, and in 1957 alone around 6,000 people died. But over the last 20 years we at the center have been making considerable progress on understanding the illness. We have produced over a hundred books and articles reporting the results of our research and in 2012 they awarded the Nobel Prize for medicine to one of my colleagues. In our more recent work we have been looking into the effects of influenza on heart diseases and we have also been exploring a possible link between climate change and the recent increase in the number of cases of influenza. It is a tragedy that the government has made this decision now.
The previous government invested huge amounts of money into the Center and I think its terrible that the present government has announced this cut when the number of cases of influenza has been increasing. The center has been running successfully for many years. But this decision is just typical of this government. It has been neglecting health research ever since it was elected, and has been cutting back on spending on science generally. Although the government says that the cut is necessary because of the recent world economic problems, I have found evidence that they have been planning this for some time. I spoke to the Minister about this yesterday and have also written (wrote) to the Prime Minister demanding that the decision should be reversed.
