September and October are good times to get a flu vaccine.
In June, the Center for Disease Control and Prevention (CDC) adopted the 2023-2024 Advisory Committee on Immunization Practices’ (ACIP) recommendations on annual influenza (flu) vaccination for everyone 6 months and older in the United States. The main change in the flu vaccine recommendations is related to giving flu vaccine to people with egg allergies.
Most flu vaccines today continue to be produced using an egg-based manufacturing process and therefore contain a small amount of egg proteins, such as ovalbumin.
While ACIP has previously recommended that all people 6 months and older with egg allergy should be vaccinated for flu, in the past there have been additional safety measures recommended for administration of egg-based flu vaccine to people who have had severe allergic reactions to egg. The ACIP voted that people with egg-allergy may receive any flu vaccine (egg-based or non-egg based) that is otherwise appropriate for their age and health status. Additional safety measures are no longer recommended for flu vaccination beyond those recommended for receipt of any vaccine. [source]
