Important to sleep well after vaccines

2nd August 2012

Vaccines are more effective if the person having the injection has a good night’s sleep.


Researchers found that sleeping for more than seven hours could help the human body react more efficiently to vaccinations.

However, they also suggest that a lack of sleep may actually leave the patients unprotected after discovering that some volunteers receiving a hepatitis B vaccine who had fewer than six hours sleep a night showed no response to the jab.

The results were published in the journal Sleep and cover 125 people who were administered the standard three-dose hepatitis B vaccine.

The first and second doses were administered a month apart, followed by a booster dose at six months with patient’s antibody level measured prior to the second and third vaccine injection and six months after the final vaccination.

As a key part of the research, those taking part kept sleep diaries and 88 of the group wore electronic sleep monitors.

From that, researchers saw that people who had less than six hours sleep a night were 11.5 times more likely to be unprotected than people who had an average of seven hours or more sleep each night.

Lead author Eric Prather said sleep deprivation had become a way of life for many people with the emergence of longer working hours and a 24-hour lifestyle.

“These findings should help raise awareness in the public health community about the clear connection between sleep and health,” he said.

The study was carried out at the University of California San Francisco.
