Vaccines are one of the greatest public health advancements of all time, resulting in the control, elimination, or near-elimination of numerous infectious diseases that were once pervasive and often fatal. Pfizer has a rich history in vaccine research and development. We have designed novel vaccines based on new delivery systems and technologies that have resulted in vaccines to prevent bacterial infections, like those caused by Streptococcus pneumoniae and Neisseria meningitidis, and viral diseases.
Today, more people are benefiting from safe and efficacious vaccines to prevent infectious diseases than ever before, and vaccines provide essential health benefits at all ages, from maternal and infant populations to seniors. However, our work is not done given the many infectious diseases remaining with a high unmet medical need and a growing list of vaccine preventable diseases.
