Thousands of older people have been given the wrong flu jab and may be at risk this winter, it is being reported.
Those affected are likely to be called back to be given an effective vaccine to prevent them catching flu. The error was revealed in a letter sent to NHS staff, reports The Sun.
The letter from Tim Davies, the NHS England lead for screening and immunisation, says the problem relates to people aged 65 and over who have been given a jab that is ineffective for their age group. Experts have called on healthcare staff to ensure all those who received the wrong vaccines are given the correct jab so they are protected.
