Rotateq who prequalified date?

What is the “prequalified” date for Rotateq (RV5)?

Rotateq (rotavirus vaccine, live, oral) received WHO prequalification (for procurement/quality approval) on 20 February 2011. [1]

Why that date matters (and what it’s not)

The WHO prequalification date is about when the product was approved for use in eligible UN/aid procurement programs. It is different from:
- the original marketing authorization date in a specific country
- later WHO reviews/updates to product information

Where this date is shown

The WHO prequalification record for Rotateq lists the prequalification date as 2011-02-20. [1]
