Allergic reactions after vaccination: translating guidelines into clinical practice

Area of Science:

• Immunology
• Public Health
• Vaccinology

Background:

• Vaccination is a critical global health intervention, effective against numerous diseases.
• Public hesitancy towards vaccines is increasing due to perceived risks of adverse events.
• Adverse reactions to vaccines are rare, with hypersensitivity reactions being even rarer.

Purpose of the Study:

• To provide a practical approach to managing adverse events post-vaccination.
• To focus on the recognition, diagnosis, and management of immune-mediated reactions.
• To aid healthcare professionals in evaluating vaccine hypersensitivity.

Main Methods:

• Review of clinical features and diagnostic approaches for vaccine adverse events.
• Development of an algorithm for allergologic work-up.
• Inclusion of a screening questionnaire for specialized care settings.

Main Results:

• Proposed algorithm aids in confirming vaccine hypersensitivity.
• Strategies ensure continued vaccination access for individuals with concerns.
• Screening questionnaire facilitates risk assessment in specialized settings.

Conclusions:

• Accurate diagnosis and management of rare immune-mediated reactions are crucial.
• A structured approach can alleviate vaccine hesitancy by addressing safety concerns.
• This review supports informed decision-making regarding vaccination.
