CVS Health immunizers are trained in the safe administration of the COVID-19 vaccines authorized for use by the FDA, including identifying and treating allergic reactions. The vaccination procedures include a patient screening checklist to assess the risk of reaction. All patients are monitored for 15 minutes after administration of the injection, or longer for people with a history of severe allergic reactions. Our immunizers are equipped with appropriate medications, such as epinephrine and antihistamines.
