An evening at the Museum of the Rockies brought history, science, and public health into focus as Montana WWAMI honored one of vaccinology’s most influential figures.
Montana WWAMI, in partnership with the Volney Steele Endowment Fund at Montana State University, hosted the Montana Medical History Conference on March 25th in Bozeman. The Life and Legacy of Dr. Maurice Hilleman: The Story of the History and Future of Vaccines explored both the impact of Hilleman’s work and the future of vaccine development.
The conference featured Dr. Barbara Kuter, Dr. Jennifer Reich, Dr. Carina Beck, and Dr. David Taylor. The speakers examined the scientific and societal dimensions of vaccines.
Dr. Taylor, an infectious disease expert with Bozeman Health, emphasized the global impact of Hilleman’s work.
“Dr. Hilleman created vaccines that prevented millions of infections and in so doing saved millions of lives,” Dr. Taylor said. “Vaccines are the most effective public health measures. Most would rank it with clean water in its impact on health.”
He noted that vaccines for measles, mumps, rubella, chickenpox, and hepatitis B have reduced infant mortality worldwide.
“Dr. Hilleman made vaccines that are used in every country in the world. The vaccines for infants such as measles, mumps and rubella (MMR), chickenpox and hepatitis B have not only controlled these infections but had a major impact on the infant mortality rate for all causes.” 
Taylor also underscored the enduring relevance of Hilleman’s approach.
“The principals that Hilleman used of identifying the etiologic agent and determining how best to make a vaccine to prevent the infection are still in use today.”
Dr. Taylor’s presentation highlighted the complexity behind vaccine development and the breadth of Hilleman’s contributions.
“What I was describing is how difficult it is to make a vaccine to give the audience an appreciation of what he accomplished. Hilleman not only made the vaccine; he oversaw manufacture and clinical testing,” he added.
Looking ahead, Taylor pointed to continued progress and emerging challenges, noting that vaccine development has advanced significantly since Hilleman’s time. Today, effective vaccines exist for RSV, dengue (a mosquito-borne disease), and malaria, and global attention is increasingly focused on diseases that impact other regions of the world. He also highlighted ongoing efforts to improve cost effectiveness, along with the rapid development of mRNA vaccines in response to COVID-19.
Speakers also addressed vaccine hesitancy and the importance of public trust.
“The vaccine preventable diseases have been successfully controlled, and people have forgotten how severe these diseases are,” he said. “I hope that we can find ways to give the right public health message to inspire the public to use vaccines, both as a means to protect their own children, and their community as well.”
The conference underscored a lasting message: Hilleman’s legacy lives on in both scientific innovation and the ongoing effort to protect communities worldwide.
