With the rise of the highly transmissible Delta variant of the COVID-19 virus, stories surrounding breakthrough cases of vaccinated people continue to surface. Researchers across the country including UArizona immunologist Dr. Deepta Bhattacharya, remind us that vaccines reinforce the defenses we already have, so that we can encounter the virus safely and potentially build further upon that protection. Prepped by a vaccine, immune reinforcements will be marshaled to the fore much faster—within days of an infection, sometimes much less.
