Understanding Manufacturer Data
•Market presence matters: More reports often reflect more doses distributed, not necessarily more safety issues.
•Reporting varies: Newer vaccines and those under heightened scrutiny tend to have higher reporting rates.
•All manufacturers meet FDA standards: Safety and efficacy requirements apply equally to all approved vaccines.
