Vaccines have significantly reduced the threat of diseases that were once widespread and oftentimes fatal. Today, more people benefit from safe and efficacious vaccines than ever before - and the list of diseases that vaccines can help prevent continues to grow. Vaccines prevent infections from serious, life-threatening diseases and they can also help reduce health care costs to both patients and the broader health care system by reducing the incidence of vaccine-preventable illness.
The development of vaccines to prevent serious disease is an extraordinary story of medical achievement - one in which Pfizer and its 'legacy' companies have played a critical role for more than a century.
Today, Pfizer is helping to usher in a new era of vaccine innovation - both to prevent and treat disease. As the global leader in pneumococcal disease prevention, Pfizer will continue to push the boundaries of innovation to pursue the next scientific breakthrough for the prevention of pneumococcal disease. In addition, Pfizer is developing vaccines that target meningococcal serogroup B disease - which is an important cause of meningitis and bloodstream infections for which no vaccine is currently available, and a vaccine for Staphylococcus aureus - the leading cause of hospital-acquired infections.
