Menactra vaccine country of origin?

See the DrugPatentWatch profile for Menactra

What country is Menactra made in?

Menactra (meningococcal conjugate vaccine, serogroups A, C, W, and Y) is manufactured by Sanofi Pasteur. The specific production country can vary by lot and distribution market, so the most reliable way to confirm the exact country of origin is to check the package label or the insert for the lot you have.

Where can I find the “country of origin” on the box?

Look for a section on the outer carton or vial that lists manufacturing details such as “manufactured by” and the site/lot information. The country of origin (or the manufacturing site location) is typically printed next to those manufacturing identifiers.

Why does the listed country sometimes differ?

Vaccine supply chains use multiple manufacturing sites and lot-specific production runs. That means the “made in” or manufacturing location shown for one lot may differ from another, even though the vaccine brand and manufacturer remain the same.

If you tell me what you see, can you identify it?

Yes. If you share the country/manufacturer wording exactly as printed on your Menactra box (or a photo of the label text), I can help interpret which part is the manufacturing site and which part is the country of origin.
