Pfizer begins testing use of pnuemococcal vaccine along with COVID-19 booster shot

Pfizer Inc said on Monday it has started immunizing the first patients in a new study looking at administering the company's 20-valent pneumococcal conjugate vaccine candidate following a booster dose of the Pfizer-BioNTech COVID-19 shot.

The study will include 600 adults over 65 years who will be recruited from the late-stage study of the Pfizer-BioNTech COVID-19 vaccine, and will have received their second dose of the vaccine at least six months prior to entering the co-administration study, the company said.
