Yuma County to receive more Johnson & Johnson vaccine Ramped up production promises larger shipments - CBS 13's Cody Lee reports YUMA, Ariz. (KYMA, KECY) - The Director of the Yuma County Public Health Department (YCPHD) says the county could get more and more doses of the Johnson & Johnson coronavirus vaccine as production ramps up. The state's top doctor, Dr. Cara Christ, and YCPHD Director Diana Gomez both say the single-dose shot works are better suited to rural areas, like Yuma County, because its storage requirements are much less complicated, the the Pfizer version. It requires special super-cold freezers. The Johnson & Johnson vaccine arrived in Yuma County for the first time earlier this week. However, the county only received a few doses. Now President Joe Biden says he plans to purchase 100 million doses to build the country's vaccine stock.
