For obese, vaccine needle size matters
Our ever-expanding waistlines may have outgrown the doctor’s needle, researchers say, in what could be another casualty of the Obesity epidemic.
In a new study, the researchers report that using a standard 1-inch needle to immunize obese adolescents against hepatitis B virus produced a much weaker effect than using a longer needle.
“As Obesity rises in the US, we need to be aware that the standard of care may have to change to protect obese youth,” study co-author Dr. Amy Middleman of Baylor College of Medicine in Houston told Reuters Health.
