The Orange County Fire Authority set up popup tents in Irvine to give staff the vaccine.

“These are the men and women on the frontlines,” said Chief Brian Fennessy with the O.C.F.A. “These are the people truly making the first contact with COVID-19 patients.”

Healthcare workers said many of the patients they have seen in the ICU tested positive for COVID-19 after attending private gatherings for Thanksgiving.

Experts worry that after Christmas there will be another surge in coronavirus cases, similar to the spike seen after Thanksgiving.

“The surge has increased exponentially so to see so many firefighters and paramedics getting the vaccine makes me very happy,” added Chief Fennessy.

The 100 doses of the Moderna vaccine, like the Pfizer vaccine, must be given in two doses, so firefighters and paramedics will not have full immunity for about a month.
