Flu jabs more effective in morning

The Medical Research Council has found that flu jabs can be made more effective by changing the time of day they are given.

Scientists believe they work best for men in the mornings and women in the afternoons and that synchronising the jab with the body’s natural daily cyclical rhythm makes it more likely to offer good immunity. Researchers will test their theory on GP patients in Birmingham with 300 patients given morning or afternoon vaccination appointments which will be determined by their gender.
