The CSSE confirmed there were 280,329 COVID-19 cases in Contra Costa County by Dec. 13.
There were 1,487 fatalities, equalling 0.5 percent of Contra Costa County's COVID-19 patients.
More than 50 percent of US citizens are considered fully vaccinated against COVID-19, nearing the target for "herd immunity." Herd immunity happens when enough of the population has become immune to the virus from previous infection that it effectively protects those who are not immune.
"The number of people who are immune to the coronavirus is increasing every day," professors David Dowdy and Gypsyamber D'Souza said in an interview.
