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.

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.
