Flu shot less effective for obese adults

(Springer) Although influenza vaccines are currently the best forms of protection to safeguard people against the flu, they are not effective in all cases. A study from Melinda Beck's research team at the University of North Carolina at Chapel Hill, US found that obese people -- despite getting their shots -- were still twice as likely to develop influenza or flu-like illnesses than others of healthy weight. The findings are published in Springer Nature's International Journal of Obesity.
