Many potential flu victims have not been vaccinated despite winter approaching, according to new figures.
As of last week, only 48.9% of over 65s had been given the jab, compared with 54.8% in the same period of 2011.
There has also been a drop for younger people who suffer from medical conditions like asthma and diabetes.
Professor Nick Phin from the Health Protection Agency told BBC Breakfast why fewer people had been getting flu jabs.
