Post-boost, we pump out more antibodies than we did after the first shots; they’ll naturally take longer to dip below a protective threshold. Repeat exposures to a vaccine can also up the quality of antibodies, which get iteratively better at sniping SARS-CoV-2 down.

The rapid spread of the omicron variant could be a major setback for efforts to reverse sharp inequality in the accessibility of effective coronavirus vaccines around the world, public health experts warn.

COVID-19 infections have slowed over the last week in Arizona, but hospitals remain crowded and modeling suggests January is likely to be one of the most difficult months of the pandemic in the state. “For hospitals, I think it’s going to be as difficult as it was last year, it just may be for slightly different reasons," said Joe Gerald, MD, PhD, an associate professor in the Mel and Enid Zuckerman College of Public Health.

Saskia Popescu, PhD, an adjunct professor of public health, said the White House's new omicron measures must be paired with additional precautions at the community level, such as wearing masks at large events and limiting indoor gatherings in areas with high transmission.

People who are diabetic are more susceptible to serious cases of COVID-19 and further health complications, and having diabetes can elevate the likelihood of having a breakthrough case of COVID-19. Shad Marvasti, MD, MPH, director of public health, prevention and health promotion at the College of Medicine – Phoenix, spoke to The Show about the connections between diabetes and COVID-19.

The Anti-Racist Transformation in Medical Education initiative, which launched in October, brings together a cohort of 10 medical colleges in the U.S. and one in Canada, including the College of Medicine – Phoenix, in order to shift racist mindsets and cultures through community-led programs, discussions and more.

COVID-19 dominated coverage but research by faculty, staff and students continued to advance health care and make headlines around the world.

A 2021 study from the Centers for Disease Control and Prevention shows obesity among the top underlying conditions associated with COVID deaths. The CDC also reports a pattern of "significant" weight gain during the pandemic among our nation's children. "I think it's a wake up call for us to really rejuvenate metabolic health to really pour in resources into primary prevention, to change the school lunch program, to have healthy breakfasts, breakfast and lunch available for children," said Shad Marvasti, MD, associate professor of family and community medicine at the College of Medicine – Phoenix.

Many health experts agree that three weeks is too short of an interval for an optimal immune response period between COVID-19 vaccine doses for kids. Deepta Bhattacharya, PhD, a professor of immunology in the College of Medicine – Tucson, plans to hold off on a second dose for his children until eight weeks. “From an immunological standpoint, it makes more sense to wait," Dr. Bhattacharya said.

In the last year, more than 14,000 people have died of COVID-19 in Arizona, and nearly 400 people died from COVID-19 in the last week of November alone. “To have 400 deaths (in a week) a year after vaccines have been widely available, it’s incredibly disappointing and frustrating. Most of those deaths would have been preventable with greater vaccine uptake," said Joe Gerald, MD, PhD, a professor of public health policy in the Mel and Enid Zuckerman College of Public Health.
