What is no longer considered a contraindication for the influenza vaccine?

The correct response is that a history of anaphylaxis to a previous dose of the influenza vaccine is no longer considered a contraindication for the vaccine. This change reflects updated guidelines that emphasize the importance of vaccination despite previous allergic reactions in many cases.

When examining vaccination practices, it is important to recognize that not all allergic reactions warrant complete avoidance of the vaccine. Recent recommendations state that individuals who experienced a severe allergic reaction (such as anaphylaxis) to a prior dose of the vaccine should be evaluated on a case-by-case basis, as many individuals can safely receive the vaccine again under medical supervision. The potential benefits of vaccination, particularly during influenza seasons, outweigh the risks for most of these individuals.

In contrast, a history of severe allergic reaction to eggs is still a contraindication for certain types of influenza vaccines, specifically those made with egg-based technology, due to the potential for reactions from egg protein. Multiple vaccinations are not contraindications, as they are often necessary for building immunity. Individuals with a history of asthma are also encouraged to receive the influenza vaccine because they are at a higher risk of complications from influenza.
