Introduction

Recommendations of health care providers have been shown to increase vaccine uptake, with quality of the recommendation positively associated with vaccination1,2,3. Less is known about the role of other health care staff in promoting vaccine uptake. During an office visit, a patient may encounter a receptionist, nurse, physician, laboratory or radiology technician, as well as a pharmacist after the visit. Studies have shown lower rates of COVID-19 vaccination among nurses and aides compared to physicians4, and variation in their trusted sources of vaccine information5. We examined COVID-19 vaccine concerns among a range of health care providers and ancillary staff and assessed reported vaccination of their adolescent children and intent to vaccinate younger children as part of an effort to improve pediatric COVID-19 vaccine uptake.

Methods

The study took place November 1st–December 27th, 2021 at an integrated health system with approximately 15 hospitals and 235 clinics. A web-based survey was widely distributed by organizational leaders to cascade to health care providers and ancillary staff to assess intent to vaccinate their children against COVID-19 and concerns regarding vaccination. Respondents were categorized as physicians, advanced practice providers, pharmacists, nurses, and other personnel (administrative personnel, laboratory personnel and imaging personnel). The study was approved by the Institutional Review Board, and all participants gave informed consent.

Results

Of 1883 total respondents, 1437 had children and were eligible to participate in the survey. Of these, 46% were physicians, 2% advanced practice providers, 39% nurses, 3% pharmacists, and 10% other personnel. Most providers reported receiving a pediatrician recommendation for their adolescent to be vaccinated (physician 52%, pharmacist 55%, nurse 61%, and other personnel 48%) (Table 1). Physicians and pharmacists reported higher vaccination of their children 12–17 years old (91%) compared to 61% of nurses and 59% of other personnel (p < 0.001). Physicians and pharmacists also reported higher intention to vaccinate their children 5-11 years old (80% and 75%, respectively) compared to 39% of nurses and 38% of other personnel (p < 0.001). Concerns about COVID-19 vaccines were more commonly reported by nurses and other personnel than physicians and pharmacists (Table 2); for example, more than twice as many nurses and other personnel reported concerns about allergic reactions and infertility compared to physicians and pharmacists, closely followed by concerns about the vaccines being too new and the perception that children do not need the vaccine.

Discussion

Despite overall high vaccination among respondents (92%) and no differences by provider/staff type for receipt of a pediatrician recommendation, fewer nurses and other personnel versus physicians and pharmacists reported vaccination of their adolescents and intention to vaccinate their younger children. Concerns about COVID-19 vaccines reported by nurses and other personnel also differed significantly from concerns reported by physicians and pharmacists. While all providers and staff reported safety concerns such as myocarditis and local and systemic reactions, nurses and other personnel more frequently reported concern about anaphylaxis and infertility. Although COVID-19 disease has been shown to have adverse effects on fertility and pregnancy outcomes, COVID-19 mRNA vaccines have not been found to be associated with reduced fecundity6,7. A review of anaphylaxis from the Vaccine Adverse Event Reporting System (VAERS) database found a rate of approximately 2.5–4.7 per 1,000,000 doses with the mRNA COVID-19 vaccines8. In the Vaccine Safety Datalink (VSD), anaphylaxis rates after dose 2 of mRNA COVID-19 vaccine were approximately 75% lower than anaphylaxis rates after dose 19.

Limitations of this study include selection bias given the open distribution of the survey, such that respondents may not be representative of their provider/staff type. Despite this limitation, the survey is consistent with prior findings of parental concern that a COVID-19 vaccine might cause lasting health problems for their child or serious vaccine side effects10 and expands upon prior work to identify differences in specific concerns about pediatric COVID-19 vaccination across health care providers and ancillary staff.

These findings underscore the need for focused efforts to update ancillary staff as well as all health care providers on emerging COVID-19 vaccine safety information for children. As ancillary staff have multiple interactions with pediatric patients and their caregivers before, during, and after a visit, it is imperative that they are equipped to strengthen, rather than diminish, COVID-19 vaccine recommendations.
