Are two shots of the Moderna or Pfizer vaccines enough to protect folks from COVID-19 for the foreseeable future? How about one shot of Johnson & Johnson? And if boosters are necessary, when should they be taken, and can people switch vaccine brands? 

U.S. scientists are expanding efforts to answer such questions, Carolyn Y. Johnson reports for The Washington Post. That includes a trial scheduled to launch next week that will test the effects of mixing vaccine brands if needed. 

“Scientists know that vaccine-induced immunity against most diseases wanes, but the answers to those questions about the coronavirus will begin to coalesce only in the coming weeks and months,” Johnson reports. “First, scientists need to identify a threshold — what level of immunity is too low to protect people? Then, they need to learn how long it typically takes for immunity to decay to that level. And then they need to figure out how to best boost people’s immunity.”

Data to Note

Click on the image above to see Wisconsin DHS COVID-19 vaccine data, which is updated daily.

Here’s a look at the Department of Health Services’ vaccine dashboard, which showed Thursday that 47.4% of Wisconsinites have received at least one vaccine dose, including 83% of those ages 65 and older. Meanwhile, 41.5% of Wisconsinites are fully vaccinated, including 78.9% of those older than 65. Racial disparities persist in distributing vaccines. The shares of Black, Hispanic and Native American residents to receive a dose remain below that of white residents. 

On Thursday, the state DHS reported a seven-day average of 282 new daily infections, continuing a long-term downward trend in new cases. The state also reported 37 new COVID-19 deaths, bringing the full toll to 7,040. That boosts the seven-day average to nearly 9 deaths per day.  
This chart from WisContext shows those trends.
