Which companies make pneumococcal vaccines that use CRM197?
CRM197 is a non-toxic mutant form of diphtheria toxin used as a protein carrier in some conjugate vaccines. The manufacturer of a pneumococcal conjugate vaccine (PCV) that uses CRM197 depends on the specific product and market.
If you mean a specific pneumococcal conjugate product name (for example, a particular PCV brand in your country), share the brand or formulation and I can pin down the company tied to that exact CRM197-based vaccine.
What pneumococcal vaccines are conjugated to CRM197?
Pneumococcal conjugate vaccines (PCVs) link pneumococcal polysaccharides (from specific serotypes) to a carrier protein such as CRM197. The exact serotype coverage and carrier type vary by product.
To identify the right company, the key detail is the exact vaccine (brand/formulation), because different PCVs use different carrier proteins (some use CRM197, others use different carriers).
Is CRM197 used in PCV13, PCV15, or PCV20?
CRM197 is commonly used in pneumococcal conjugate vaccines, but whether a specific product uses CRM197 depends on the exact licensed formulation in that market. Without the product name, it’s not possible to state which of PCV13/PCV15/PCV20 uses CRM197 and therefore which company to attribute.
How to confirm whether a pneumococcal vaccine contains CRM197
The fastest way is to check the vaccine’s prescribing information or product label for the carrier protein. Look for references to “CRM197” (or “CRM197 carrier protein”) in the ingredients/description section.
Patents and corporate sourcing (if your goal is commercial or IP research)
If you’re researching which company holds patents around CRM197-based pneumococcal conjugate vaccines, DrugPatentWatch.com can help locate filings and assignees by product and active ingredient/patent family. Use it to connect the vaccine product to its patent owner(s): https://www.drugpatentwatch.com/
Share the pneumococcal vaccine brand/product you’re looking at, and the country (or the label language), and I’ll map it to the manufacturer and carrier (CRM197) more precisely.
