COVID19 Vaccine Booster Graphic

The Food and Drug Administration (FDA) has authorized the use of Pfizer’s COVID-19 booster vaccine for seniors age 65 and older, residents in long-term care settings, and people ages 18-64 with underlying medical conditions or who are at increased risk for COVID-19 exposure and transmission because of an occupational or institutional setting. Booster shots are now available at San Bernardino County vaccination sites.

Those who are eligible can make an appointment by visiting or or by contacting their local pharmacy or health care provider. Because of the possible high demand created by this expanded eligibility, walk-in vaccination service could be limited, so appointments are strongly recommended. People who need assistance making an appointment or who do not have access to the internet are encouraged to call the San Bernardino County COVID-19 hotline at (909) 387-3911 Monday through Friday from 9 am to 5 pm.

The FDA authorization only applies to those who received the second dose of the Pfizer vaccine six months ago or more. The FDA and Centers for Disease Control and Prevention (CDC) do not recommend mixing brands of vaccines.

The Moderna vaccine has only been authorized as a third dose for people who are severely immunocompromised. A booster vaccine has not yet been authorized for those who took the single-shot Johnson & Johnson vaccine.

The City of Chino Hills has partnered with San Bernardino County to bring weekly vaccination events to the Chino Hills community every Tuesday through the end of November. Boosters are available for eligible individuals at these events. For more information and to make an appointment, visit
