Deepta Bhattacharya, PhD, a professor and immunobiologist at the College of Medicine – Tucson, says a booster shot may offer a little extra protection against getting sick and having to stay to recover, but it's still unknown how long this extra protection will last. "The question sort of becomes, when do we need a booster versus when do we want one. I think that's the distinction we need to have right now," Bhattacharya says.

Since the flu and COVID-19 are both respiratory illnesses, there has been speculation that having one illness makes you more likely to develop the other — and that having both at once could increase the chance of serious outcomes. “There is not enough data to answer questions whether the effects of both diseases are cumulative, whether the risk of mortality is higher, or how” the development of either disease might be different than when someone is affected by only one," said Purnima Madhivanan, PhD, an associate professor in Health Promotion Sciences at the Mel & Enid Zuckerman College of Public Health.

Health experts say there shouldn’t be any concern about getting both the COVID vaccine and a flu shot at the same time. “The immune system is pretty good at handling multiple things at once,” said Deepta Bhattacharya, a professor of immunobiology at the College of Medicine – Tucson. He noted how children often receive multiple vaccines at visits to their pediatrician.

There is widespread agreement about the importance of improving fitness levels for the management of obesity, as advocated by the fat-but-fit approach. However, there are concerns among the scientific and medical community about the degree of emphasis on weight loss and other factors associated with obesity. “It is important to recognize obesity is a multidimensional health issue with multifactorial contributors. Thus, being physically active is not a license to maintain a poor diet or to ignore other contributors to obesity. Other contributors to obesity may include issues with sleep, certain medications, the microbiome, and many more,” said Jennifer Bea, PhD, an associate professor of medicine at the University of Arizona Health Sciences.
