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.

The results suggest improving communication among family members about organ donation wishes could help increase and diversify the pool of organs available for transplantation. "It's important that we start having these hard conversations a little earlier," said Khadijah Breathett, MD, the study's senior author and an assistant professor in the College of Medicine – Tucson.

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.

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.
