Center for Vaccine Innovation and Access

Everyone has a right to lifesaving vaccines, no matter where they live. The Center for Vaccine Innovation and Access (CVIA) accelerates the development and delivery of lifesaving vaccines for the communities facing the greatest health risks around the world.

Saving lives with vaccines

CVIA has played a critical role in some of immunization’s greatest successes of the past 30 years: The world’s first malaria vaccine, which has reached more than 2 million children (and counting); elimination of meningitis A epidemics in Africa where MenAfriVac® vaccine has been introduced, with more than 360 million people immunized; protecting more than 300 million children from Japanese encephalitis, a potentially debilitating and fatal brain infection; vaccinating millions of girls in 30 countries against human papillomavirus (HPV), the leading cause of cervical cancer; and introducing the first typhoid conjugate vaccine in six countries, protecting more than 56 million children.

Tackling the toughest diseases

Our portfolio of vaccines in development and deployment includes those against the most dangerous childhood illnesses, such as pneumonia, diarrhea, and malaria. For example, beginning in 2011, we partnered to develop the world’s first malaria vaccine, and we supported implementation of the pivotal pilot introduction of the vaccine in Ghana, Kenya, and Malawi. PATH’s breadth of experience in malaria prevention and treatment, paired with our expertise in malaria vaccine implementation, uniquely equips us to support countries as they plan their rollouts of malaria vaccines.

Get our updates

  1. Moving the Needle e-newsletter

    Moving the Needle provides updates from CVIA on our vaccine development efforts, as well as related supporting work, such as developing human challenge models, building capacity of developing-country vaccine manufacturers, and evaluating new adjuvants and other novel vaccine technologies.

  2. Immunization Matters e-newsletter

    Immunization Matters provides updates from CVIA on late-stage and licensed vaccines included in our portfolio as well as our work on health economics and optimization, operations research, and support to countries.

  3. DefeatDD website

    PATH's Defeat Diarrheal Disease Initiative was started to raise awareness of the burden of diarrheal disease and help increase access to the solutions. We need your help to make a stink about the problem, and our website gives you the tools to do just that.

  4. PATH's malaria vaccine website

    PATH's malaria vaccine work drives transformative innovation to save lives and improve health, especially among women and children. We work with partners in private industry, government, and academia to develop malaria vaccines.

  5. Take on Typhoid website

    The Coalition against Typhoid (CaT) and the Typhoid Vaccine Acceleration Consortium (TyVAC) have joined forces to Take on Typhoid. Together, we are working to focus attention on typhoid and the need for typhoid conjugate vaccines and water, sanitation, and hygiene interventions to reduce the burden and impact of typhoid fever.

  6. HPVflash e-newsletter

    In HPVflash, PATH provides updates on progress in the field, new literature, events, and partnerships in an effort to eliminate cervical cancer.
