BACKGROUND/PURPOSE: Although many coronavirus disease 2019 (COVID-19) vaccine injections have been administered worldwide, the safety of this practice remains unclear. This study aimed to compare the rates of complications associated with COVID-19 vaccines administered by dentists with those of vaccines administered by nurses. This study aimed to evaluate the safety of a vaccination program delivered by dentists.
This observational cohort study included 537 recipients of the second dose of the Pfizer COVID-19 vaccine, delivered as an intramuscular injection to the upper arm deltoid muscle by dentists or nurses at the study site. Vaccine recipients were divided into two groups according to the vaccination administrator (dentist vs. nurse groups). The rates of complications associated with intramuscular injection technique (numbness in the hand or arm at the time of the injection, vasovagal reflex at the time of the injection, vaccine-related shoulder injury, and prolonged numbness) were examined.
A total of 125 vaccine recipients were included (nurse group, n = 84; dentist group, n = 41). The overall incidence rate of complications was lower in the dentist group (2.4%; 1/41) than in the nurse group (8.3%; 7/84). However, this difference was not statistically significant ( = 0.3).
This study suggests that the safety of COVID-19 vaccine administration is comparable between dentists and nurses.
背景/目的：尽管全球已接种了许多2019冠状病毒病（COVID-19）疫苗，但这种做法的安全性仍不明确。本研究旨在比较牙医接种COVID-19疫苗与护士接种疫苗的并发症发生率。本研究旨在评估牙医实施的疫苗接种计划的安全性。
这项观察性队列研究纳入了537名接受辉瑞COVID-19疫苗第二剂接种的受试者，由研究地点的牙医或护士在上臂三角肌进行肌肉注射。根据疫苗接种管理人员将疫苗接种者分为两组（牙医组与护士组）。检查了与肌肉注射技术相关的并发症发生率（注射时手部或手臂麻木、注射时血管迷走反射、疫苗相关肩部损伤和持续性麻木）。
共纳入125名疫苗接种者（护士组，n = 84；牙医组，n = 41）。牙医组并发症的总体发生率（2.4%；1/41）低于护士组（8.3%；7/84）。然而，这种差异无统计学意义（P = 0.3）。
本研究表明，牙医和护士接种COVID-19疫苗的安全性相当。
