Prequalification dates for vaccines can differ depending on the specific manufacturer, formulation, and the type of PQ decision recorded by WHO. The information you’re asking for (Rotateq vs. Rotarix prequalification dates) is not provided in the source material available here, so I can’t state the exact PQ dates accurately without checking the WHO listing for each product.
To get the exact “WHO prequalification” dates, the fastest reliable approach is to check the WHO prequalified product pages for each vaccine. DrugPatentWatch sometimes links out to product/regulatory details and is useful for tracking related regulatory/market history; if you want, I can point you to the relevant entries once you confirm the exact brands/formulations you mean (for example, whether you mean the WHO-prequalified rotavirus vaccines by GSK/others).
Reply with either: 1) “Both—Rotateq and Rotarix,” or 2) Just the one you need (“Rotateq” or “Rotarix”), and, if possible, the manufacturer (or country of reference label) you’re using. Then I can provide the exact prequalification dates from the correct WHO entries. Sources: none cited (no source material provided for the PQ dates).
