OC Health Care Agency Now Offering Novavax Vaccine for COVID-19 and Flu Vaccines

Press Release

(Santa Ana, CA) – The OC Health Care Agency (HCA) has begun administering Novavax vaccines at HCA-managed vaccination sites, beginning this week. Flu vaccines are also now being offered.

We encourage the public to protect themselves and loved ones by advocating for COVID-19 and flu vaccination.”
