A new study published in the Journal SLEEP shows that getting less than 6 hours of sleep can lower the potency of vaccines.
There is more work to be done to examine the sleep patterns, but based on the findings of study researcher Aric Prather, Ph.D., lack of sleep may significantly affect the potency of vaccinations. The study consisted of 125 people from ages 40-60 who were given three doses of the hepatitis B vaccine over a 6 month period. The participants were asked to keep detailed sleep diaries, and were measured by the researchers for the amount of anti-bodies they had over the course of a year after the initial dose of vaccine.
Researchers did find evidence between the amount of time participants slept, and the potency of the hepatitis B vaccine, they did not however find a link between the sleep quality and vaccine potency.
