Description Vaccination has emerged as a pandemic off-ramp across the world,
but waning immunity over time and the emergence of new variants
have illustrated the importance of booster shots in achieving and
sustaining immunity. This research studies the factors that affect the
likelihood that individuals will receive the booster. Between December
14-17, 2021, a choice-based conjoint was conducted to estimate
respondents’ likelihood of receiving a booster. The analysis focuses
on the 549 respondents who were fully vaccinated but had not yet
received a COVID-19 booster at the time of our survey. Booster attributes
included efficacy defined as protection against symptomatic
illness, protection duration, manufacturer, and monetary incentives.
Attributes were randomly assigned for hypothetical vaccines. Conjoint
analysis showed high efficacy rates had the largest impact on
reported likelihood of receiving a booster, followed by financial incentives.
Protection duration and protection against future variants
had modest effects. Subjects most preferred a booster by Pfizer,
followed by Moderna, and then by Johnson & Johnson. Finally, an
opening contextual experimental prime telling respondents that early
results suggest the omicron variant could be more contagious, but
less lethal than earlier variants (vs. a control group baseline in which
both were described as unknown) significantly increased likelihood
of receiving the booster.
