Frequently asked questions about Pneumococcal Conjugate Vaccine

What is Pneumococcal Conjugate Vaccine used for?

Pneumococcal Conjugate Vaccine is used for pneumococcal immunization, which helps protect against infections caused by Streptococcus pneumoniae bacteria. It is being studied for use in healthy toddlers, infants, and adults to prevent pneumococcal disease.

Who makes Pneumococcal Conjugate Vaccine?

Sanofi (ticker: SNY) is developing the Pneumococcal Conjugate Vaccine. The company is conducting clinical trials to evaluate the vaccine's safety and immunogenicity in different age groups.

What phase is Pneumococcal Conjugate Vaccine in?

Pneumococcal Conjugate Vaccine is in Phase 1 clinical development. It is an investigational vaccine and has not been approved by regulatory authorities. Clinical trials are ongoing to assess its safety and immune response.

What clinical trials is Pneumococcal Conjugate Vaccine in?

Pneumococcal Conjugate Vaccine has been studied in two clinical trials. NCT04398706 was a Phase 2 study in toddlers and infants, and NCT06698198 was a Phase 1 study in healthy adults aged 19-49 years. Both trials have been completed.

Is Pneumococcal Conjugate Vaccine the same as other pneumococcal vaccines?

Pneumococcal Conjugate Vaccine is a specific vaccine candidate developed by Sanofi. It is not referred to by any alternative names in the available data. It is distinct from other pneumococcal vaccines on the market.
