Vaccination represents one of the largest advances in public health of the past century, with new vaccines and vaccination programs leading to reduced rates of sickness and death, improved lifespans and even disease eradication in some cases. Yet many people remain unvaccinated, in part due to limited access to vaccination services. Since the 1990s, many states have changed their laws to give pharmacists the authority to vaccinate to help close this gap. However, these laws vary from state to state and many have dramatically changed over the years.

To understand how laws shape pharmacists’ authority to vaccinate, and what that might mean for vaccination rates, Mr. Cason Schmit, research assistant professor in the department of health policy and management of the Texas A&M School of Public Health, and Mr. Matthew Penn, director of the Public Health Law Program at the Centers for Disease Control and Prevention, studied vaccine-related laws in different jurisdictions in the United States.
“We found that when states change their laws, they are generally choosing to expand pharmacists’ vaccination authority rather than to restrict it,” Mr. Schmit said. “The consistent expansion of pharmacists’ vaccination authority flies in the face of some concerns about pharmacists disrupting regular physician visits, poor documentation and communication between physicians and pharmacists and concerns about sufficient training.”
Only three states, California, New Hampshire and North Carolina, changed laws to restrict vaccination authority. However, all these states changed their laws again to provide an even greater expansion of pharmacists’ vaccination authority later.
In 2016, most of the jurisdictions studied had laws explicitly authorizing pharmacists to vaccinate, with 37 jurisdictions permitting pharmacists to vaccinate multiple patients under a single prescriber’s authorization (in other words, a standing order) and 10 giving pharmacists the independent authority to administer vaccines without authorization from a physician or other prescriber. An additional five jurisdictions did not specifically grant pharmacists prescriptive authority or permit use of standing vaccination orders, but they did not explicitly forbid expanded pharmacist authority either.
In 2016, seven states limited pharmacist-administered vaccinations to adults, and the remaining jurisdictions either had minimum age limits ranging from three to 14 years or had no explicit minimum-age restriction. “We found many laws placing restrictions on minimum patient age or vaccine types,” Mr. Schmit said. “The average minimum age was 16.8 years in 2005 and 8.76 in 2016, showing a trend toward pharmacists vaccinating younger patients.”
The study also uncovered a trend toward pharmacists dispensing more vaccines. Some laws listed the types of vaccines allowed, whereas others either authorized vaccines recommended by the Advisory Committee on Immunization Practices or had no restrictions on specific vaccines.
These results show that states have made significant changes to laws granting pharmacists more authority to vaccinate. Specifically, the study identified trends toward reduced oversight by physicians, lowering age patient minimum age limits and an increase in the number vaccines allowed. There is also a growing recognition, contrary to earlier concerns, that pharmacists are an effective way to vaccinate more of the population. However, further research is needed to identify which types of vaccine-related laws are best suited to increasing vaccination rates.
“Unfortunately, while these authority expansions might seem like they are promoting access, there are still substantial barriers to accessing effective vaccination” Mr. Schmit said. “Many states still have vaccine or patient-age restrictions that prevent pharmacists from administering vaccines as recommended by the Advisory Committee on Immunization Practices.”
