Common questions
How do I find my meningococcal vaccine lot number?
The lot (batch) number is printed on your vaccination record card, on the vial or prefilled syringe label, and in your clinic's immunization record or state registry printout. It is usually 5–8 characters, letters and numbers.
What does a high report count for a meningococcal vaccine lot mean?
Mostly that the lot was large or widely distributed, or shipped during a period of intense reporting. VAERS counts have no denominator unless shipment data is known, so a lot with more reports is not shown to be more harmful; compare the per-million-doses column where available and read the lot explorer's caveats.
Does a VAERS report mean the vaccine caused the event?
No. VAERS accepts any report from anyone; it is a signal-detection system, not a causal record. Reports are unverified and incomplete, and the same event can be reported more than once.
