What Challenges Exist in Vaccine Pharmacovigilance?
Despite its importance, vaccine pharmacovigilance faces several challenges, including:
Underreporting: Not all adverse events are reported, which can skew data. Causality Assessment: Determining whether a vaccine caused an adverse event can be complex. Data Quality: Ensuring that the data collected is accurate and reliable. Global Harmonization: Different countries may have different reporting standards and regulations, making it challenging to aggregate and compare data globally.
