“With its fast transmission rates, we anticipated the omicron variant appearing locally,” said Dr. Maggie Park, San Joaquin County Public Health Officer. “That’s why we continue to encourage anyone who’s eligible to get vaccinated and get a booster—especially as people consider gathering for New Year’s. As we start 2022, let’s do our best to protect ourselves and those around us through testing and vaccination.”
