Vaccines are one of the greatest public health advances of all time. They have controlled and prevented the continued spread of many infectious diseases by teaching individuals’ bodies to fight off the diseases before they become sick. Similar to clean water and good sanitation, vaccines safeguard our communities and help people stay well, productive, and active.
At Pfizer, we believe in the power of vaccines to provide infants, children, adolescents, and adults with the best protection possible against infectious diseases. Over many years, Pfizer has played a key role in eliminating, or nearly eliminating, deadly infectious diseases like smallpox and polio globally.
The COVID-19 pandemic has reinforced the importance of vaccine development — and the importance of participation in vaccine clinical trials. We are grateful to the tens of thousands of people who chose to participate in our COVID-19 vaccine trials. Similarly, there are many people who have volunteered in clinical trials for other important vaccines. Thank you all participants: Without them, new vaccines could not be developed.
