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 whilst also providing broader societal and economic benefits.1




Pfizer has a rich history in vaccine research and development. Over the years, we’ve played a pivotal role in eliminating or nearly eliminating deadly infectious diseases like smallpox and polio globally. 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 S. pneumoniae and N. meningitis.

However, our work is not done given the many infectious diseases remaining with a high unmet medical need. It's an exciting time for vaccine research and development as scientific discoveries, technological advancements and regulatory processes are paving the way for novel vaccines.

We are focusing our vaccines research and development across three areas; addressing high impact infectious diseases, expanding the benefits of maternal immunisation and investigating cancer vaccines.
