By Ted Asregadoo, iHeart Media Jan 8, 2021 Pfizer BioNTech Covid-19 Vaccine COVID-19 vaccinations are now being given to Sacramento area firefighters and paramedics. The expansion of the Phase 1A category is part of the program to vaccinate three million at-risk workers and residents in the state. Because the Moderna and Pfizer vaccines require sub-zero degree storage, health officials say expanding its distribution means doses aren't wasted. Sacramento Fire Department spokesperson Captain Keith Wade noted that he wants to see "100-percent" of first responders receive shots. He's concerned that a new strain of the virus that spreads faster will lead to staffing shortages.
