Pfizer said its experimental pneumococcal vaccine produced a significantly stronger immune response than its current shot in a mid-stage study, with up to 15-fold higher antibody levels against a key strain. The data support the program’s competitive profile and may improve the vaccine’s commercialization prospects if later-stage results confirm the findings. The news is positive for Pfizer but remains early-stage and is unlikely to be a major market mover on its own.
