Views on COVID-19 and Vaccination

Overview

The goal of this study is to develop evidence-based messages that effectively mitigate concerns of people at risk for not being vaccinated against COVID-19, with the ultimate goal of maximizing vaccine uptake in vulnerable populations. The investigators will collect data on COVID-19 disease and vaccine knowledge, beliefs, and intent to be vaccinated from an existing online panel. Results from this data collection will be used to develop effective messages and communication strategies. The investigators will test alternate versions of messages intended to reduce vaccine hesitancy and promote vaccine uptake among vaccine-hesitant individuals. This project will ultimately result in a set of tested, evidence-derived messages about vaccination for COVID-19.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly instigated a global pandemic. As of this writing, there are approximately 65 million documented cases of infection worldwide, and over 1.5 million deaths. In the United States (US), coronavirus disease 2019 (COVID-19) has disrupted the economy, overwhelmed healthcare system, led to widespread school cancellations, and caused more than 274,000 deaths since March 2020. A vaccine against COVID-19 is widely viewed as the key to controlling the pandemic and enabling a return to "normal" life. Vaccine development is proceeding at an unprecedented pace with 10 vaccines currently in phase 3 trials. Experts have projected that a safe and effective vaccine may be available by mid-2021. At the same time, a growing body of evidence indicates that a significant proportion of adults in the U.S. may not accept vaccination against COVID-19. Even more alarming, COVID-19 vaccine hesitancy (refusal or reluctance to accept a vaccine) appears to be increasing as the vaccine approval process becomes increasingly politicized. Just as efforts to develop vaccine production and delivery capacity have been undertaken in advance of having a proven effective vaccine, parallel efforts are needed to identify effective messages and communication strategies to overcome COVID-19 vaccine hesitancy. The study team recently surveyed a nationally representative sample of approximately 1,000 adults in the United States and found that only 57% intended to be vaccinated when a coronavirus vaccine becomes available. This percentage was even lower among people who identified as Black or Hispanic (39% and 43% respectively), those with a high school education or less (46%), and those in the lowest income groups (49% of those reporting a household income of $30,000 or less, compared to 72% of those reporting a household income of $100,000 or more). The investigators asked those who indicated they would not or might not get vaccinated for their reasons and found that some individuals may be willing to be vaccinated if provided specific information about the vaccine such as side effects and effectiveness. Others expressed generalized skepticism, fear, and distrust of vaccines, with some even referring to anti-vaccine conspiracy theories. These findings are consistent with an extensive body of research documenting that people often do not behave rationally and highlight the urgent need to proactively develop and test interventions to maximize vaccination rates when a coronavirus vaccine becomes available. To address this need, in the present study, the investigators aim to create and test targeted messages to address the concerns of subgroups of people at risk for not being vaccinated, with the ultimate goal of maximizing vaccine uptake when a vaccine for COVID-19 becomes available. The investigators will accomplish this by working with an existing online panel of volunteers, which will allow efficient, focused data gathering. Results of the survey will provide a nuanced, current description of how vulnerable adults perceive the coronavirus and available vaccines, which will be used as the basis for developing messages and communication strategies. Participants will be randomized to receive one of five different versions of a message from a healthcare provider regarding vaccination. Specific wording and content of these messages will vary systematically in order to address concerns of those at risk for not being vaccinated. This project will ultimately result in a set of tested, evidence-derived messages about vaccination for COVID-19. The investigators will make these messages available, together with evidence of how these influence members of vulnerable populations' understanding of vaccination, and disease risk, as well as intent to be vaccinated. The messages will be freely available for use by organizations and providers seeking to improve communication about a coronavirus vaccine.
