Vaccine Hesitancy: What Public Health Professionals Should Understand

Discover the reasons behind the hesitancy, and how an online degree in public health can prepare you to keep communities healthy.

Vaccines reduce our risk of disease by working with our body’s natural defenses to develop immunity. They are an important part of public health, saving millions of lives each year by preventing diseases like polio, measles, and tetanus.1

While studies have shown that vaccines are safe and effective, many people are hesitant to receive them.2


By understanding the reasons for this hesitancy, public health professionals, health educators, and community health workers can address barriers and offer solutions to keep overall infection rates low.

The Reasons Behind Vaccine Hesitancy

In 2019, the World Health Organization listed vaccine hesitancy—the reluctance or refusal to vaccinate despite the availability of vaccines—as one of the top 10 threats to world health.3 Children are especially impacted. The majority of U.S. children receive the recommended vaccinations, but the percentage of babies in the U.S. ages 19 to 35 months who haven’t received any vaccinations more than quadrupled between 2001 and 2015.4

There are four overarching categories for why parents refuse, delay, or are hesitant to vaccinate their children:5

  • Religious reasons
  • Personal beliefs or philosophical reasons
  • Safety concerns
  • A desire for more information from healthcare providers

Social media hasn’t helped. A recent study found a significant relationship between the use of social media to organize offline action and increased belief that vaccinations are unsafe.6 It also found a substantial relationship between foreign vaccine disinformation campaigns and declining vaccination coverage.

Refusing to vaccinate can contribute to outbreaks of dangerous and possibly deadly diseases. In 2019, the U.S. Centers for Disease Control and Prevention confirmed 1,282 cases of measles in 31 states—the greatest number of cases reported in the United States since 1992. The majority of those cases were among people who were not vaccinated.7

How Public Health Professionals Can Help

People working in public health careers play an important role in educating communities about vaccine benefits and addressing and measuring reasons for under-vaccination. Public health professionals and health educators can have a successful dialogue with families by:8

  • Taking the time to listen. Give patients and parents your full attention when discussing vaccine concerns.
  • Soliciting and welcoming questions. Ask open-ended questions and remind patients that their health is your top priority.
  • Using science and anecdotes. Be prepared to use a mix of science and personal stories to address questions.
  • Acknowledging benefits and risks. Discuss the known side effects of vaccines but reiterate the overwhelming benefits that come with them, like preventing serious diseases.

Public health professionals can also support programs to track vaccine data over time and develop strategies to increase vaccination acceptance and demand.
