Many factors weaken the aging immune system. But vaccines—and booster doses—do offer protection from hospitalization and death. Experts say they still don’t have an adequate explanation for why older people were more susceptible to COVID-19 even before vaccines were available. “It’s just one of the great mysteries of the virus,” says Deepta Bhattacharya, PhD, professor of immunobiology at the College of Medicine – Tucson.

Regardless of legal status or nationality, the different Mexican consulate offices in Arizona offer free health services. “When you immigrate to the U.S., access is a challenge for many people. The health systems are different in both countries and therefore we need to educate the migrant population and connect them with health services,” said Cecilia Rosales, MD, MS, associate dean of community engagement and outreach at the Mel and Enid Zuckerman College of Public Health.

The relatively low number of West Nile cases has been a roadblock for development of a vaccine. In Phase III clinical trials, a significant number of individuals has to be infected and enrolled in order for a vaccine or treatment to demonstrate efficacy. Only a proven effective vaccine will be approved for use in humans, explained Deepta Bhattacharya, PhD, a professor of immunobiology at the College of Medicine – Phoenix. “That was one of the reasons why the SARS-CoV-2 vaccines were able to be deployed so quickly: at the time Pfizer and Moderna were testing the vaccine, there was a ton of community spread,” Dr. Bhattacharya said.

Continuing coverage: Scientists at the University of Arizona and Arizona State University released a study in Science Advances that explains how and why molar teeth emerge in stages during your and why that happens so much more slowly compared to other living apes. “One of the mysteries of human biological development is how the precise synchrony between molar emergence and life history came about and how it is regulated," said lead author Halszka Glowacka, PhD, assistant professor and co-director of the clinical anatomy program at the College of Medicine – Phoenix.

Congressional Valley Fever Task Force Co-Chair and Congressman Kevin McCarthy introduced a bipartisan bill, the Finding Orphan-disease Remedies with Antifungal Research and Development (FORWARD) Act of 2021, to combat Valley fever. “This year in Arizona, our data shows that for every four new diagnoses of COVID-19, an additional person with the same symptoms has Valley fever,” said John Galgiani, MD, director of the Valley Fever Center for Excellence at the University of Arizona College of Medicine – Tucson.
