What Are the Challenges in Vaccine Safety Surveillance?
Despite its importance, vaccine safety surveillance faces several challenges:
Underreporting: Not all adverse events are reported, particularly in passive surveillance systems. Data Quality: Incomplete or inaccurate reports can affect the analysis and interpretation of data. Causality Assessment: Determining whether an adverse event is causally linked to the vaccine can be complex. Public Perception: Negative media coverage and misinformation can undermine public confidence in vaccines.
