Request

I'm a neurologist in the UK planning to do some research on PML and wanted to check if you're able to provide some up to date information on figures for the UK based on yellow card reporting? I noticed that on the Gov UK site they had figures up to 2008 (Info on progressive multifocal leukoencephalopathy (PML) from Yellow Card reports - GOV.UK), and case reporting for the years following on would be very helpful.
