SIR, Age Cymru is encouraging readers who have health conditions such as diabetes, respiratory problems or heart and kidney disease, to have their free seasonal flu jab. Over 65s are automatically eligible for this protection. It is vital that older people who have underlying health conditions – such as those mentioned above – have their free flu vaccination. This is because their existing conditions could be complicated or made worse if they catch the flu. Despite this fact, take up of the jab so far this winter across Wales has been low. The flu virus is now circulating in Wales, so please speak to your GP or practice nurse at the earliest opportunity to make an appointment for your winter flu vaccination which is available for free on the NHS for people who qualify.  Angharad Phillips (Age Cymru)
