The sprint to develop vaccines effective at preventing COVID-19 infection and its subsequent complications is unprecedented in modern medicine. Presently, three companies have been granted emergency use authorization from the FDA for their COVID-19 vaccines: Pfizer\/BioNTech, Moderna, and, most recently, Johnson & Johnson. More vaccine candidates continue to progress through the pipeline. As of today, millions of Americans have received at least one dose of a COVID-19 vaccine, and nearly 12% of the U.S. population has been fully vaccinated against COVID-19.<\/p>\n
As the COVID-19 vaccines increase in availability in the United States, one significant factor affecting uptake in the U.S. and around the world is something called vaccine hesitancy. Recent studies suggest that 30-40% of Americans are unlikely to receive the vaccine. Even when accounting for those who have immunity from contracting COVID-19, this would mean that we may not reach a vaccination rate of 70% or more required to provide herd immunity in the U.S., which is when enough people become immune to a disease to make its spread unlikely.<\/p>\n
The World Health Organization defines vaccine hesitancy as “a delay in acceptance or refusal of vaccines despite availability of vaccine services.” Chen says that the most important factor affecting our health decisions, including whether or not to receive a vaccine, is our health beliefs. These health beliefs are formed through a complex interplay of a person\u2019s background, experiences, convictions, and beliefs. This forms our idea of what causes a change in our health status, how susceptible we may be to a health risk such as COVID-19, the perceptions of the severity of any illness, and what we can do to control our health. Additionally, the model recognizes that health is much more than physical. As human beings, health is a state of well-being that includes our bodies, our minds, our spirits, and our relationships.<\/p>\n
According to Chen, factors that may lead a person to express hesitancy about vaccines fall into one of three categories: confidence, complacency, and convenience. These can range from beliefs about the safety or efficacy of vaccines, one\u2019s personal experience with vaccines or the healthcare system, and cultural views on the perceived benefits and risks of vaccination. These health beliefs about vaccines can also be influenced by race, ethnicity, political views, and social media, among many others.<\/p>\n
The autonomy of each person to make decisions about their own treatment is something that healthcare providers have an ethical responsibility to uphold. According to Dr. Chen, \u201cWe want freedom to make our decisions. We have control over our own bodies to a certain extent, and I recognize the value of each person\u2019s ability and need to make their own decisions.\u201d Stemming from this desire, Chen believes that patient-centered communication strategies, such as motivational interviewing, value this ethical commitment, allow healthcare providers to demonstrate empathy, and provide an opportunity for dialog between the provider and patient. Preliminary data suggest that this may be an effective way to encourage vaccine confidence while honoring the person\u2019s ability to make an informed decision.<\/p>\n
