Some doctors and researchers say there's not enough evidence from clinical trials that a new Alzheimer's drug is effective. Roberta Brinton, PhD, Director of the Center for Innovation in Brain Science, hopes the benefits outweigh the harm. "There are many roads to Alzheimer's, there are many on-ramps to Alzheimer's but there aren't any off-ramps yet. I think it's a game starter and it's very exciting the FDA was flexible in their approval process," Brinton said.

If someone has already become infected and then recovered from COVID, do they still need to receive a vaccine? “From a population perspective, we can’t reassure individuals what their current antibody status is, even if they had an infection—and because of the variants," said Pima County Health Director Dr. Theresa Cullen, a clinical associate professor in the College of Medicine – Tucson.

A Republic investigation found that stem cells have been marketed as a treatment for conditions that have no good existing treatments, like arthritis, Alzheimer' or even autism.

Saskia Popescu, an infectious disease epidemiologist and adjunct professor at the Mel and Enid Zuckerman College of Public Health, said she wants people to get vaccinated and enjoy more flexibility. But she also doesn’t want Americans to forget — especially as they’re considering traveling outside the country — that they’re in a position that much of the world envies. “Be cognizant that other places are struggling,” Popescu said.

Ivo Abraham, a professor at the College of Pharmacy, is concerned that a recent drop in e-cigarette use by teens isn't a trend, but merely a pause in an increasing trend.
