Abstract：
OBJECTIVE: To examine user experiences in a moderated Facebook group intervention aimed at Coronavirus disease 2019 (COVID-19) vaccine promotion.
METHODS: Facebook group members were given 2-3 vaccination posts/day for 28 days (four weeks). Posts were aimed at educating about COVID-19 vaccination, soliciting concerns around COVID-19 vaccination, and engaging members. Participants were surveyed about their experience at four weeks.
METHODS: Moderated Facebook group.
METHODS: Unvaccinated individuals who were randomized to the intervention group and completed four week follow-up (N = 216, 82.1%).
METHODS: After four weeks, participants rated their experience in the Facebook group (eg, program satisfaction) and provided open-text responses about their satisfaction with the group. Free-text responses were dual coded and emergent themes were examined.
RESULTS: On average, participants were 37.0 years old (SD = 10.3), majority female (70.9%), and white (79.7%). The majority of participants were satisfied with the group (76.7%), agreed that other people were friendly (M = 5.58/7), and felt safe discussing health information (M = 3.96/5). Open-text responses revealed that participants liked the program because they thought the information was useful (27.7%), other members were friendly (16.1%), and the group was a safe place (13.8%). While many responded that there was nothing they did not like about the program (37.6%), nearly one-third (31.9%) reported disliking the program because it appeared to be too much in favor of vaccination and because other members came across as rude (7.1%). Those with conservative political views were less likely to be satisfied with the group (P = .04).
CONCLUSIONS: Facebook groups represent an acceptable way to engage participants to improve vaccination against COVID-19. Some aspects of the Facebook group could be improved for future iterations.

摘要：
目的：检查用户在针对2019年冠状病毒病（COVID-19）疫苗推广的Facebook群组干预中的体验。
方法：Facebook小组成员每天接种2-3次疫苗，持续28天（四周）。这些帖子旨在对COVID-19疫苗接种进行教育，引起人们对COVID-19疫苗接种的关注，和参与成员。参与者在四周时接受了他们的经历调查。
方法：调节Facebook群组。
方法：未接种疫苗的个体被随机分配到干预组，并完成四周的随访（N=216，82.1％）。
方法：四周后，参与者对他们在Facebook小组中的经历进行了评分(例如，计划满意度)，并提供了关于他们对小组满意度的开放文本回复。对自由文本的回答进行了双重编码，并检查了紧急主题。
结果：平均而言，参与者年龄为37.0岁(SD=10.3)，女性占多数（70.9%），和白色(79.7%)。大多数参与者对该组感到满意（76.7％），同意其他人是友好的（M=5.58/7），并感到安全讨论健康信息（M=3.96/5）。开放文本回答显示，参与者喜欢该程序，因为他们认为信息是有用的（27.7％），其他成员友好(16.1%)，该组是一个安全的地方（13.8%）。虽然许多人回答说，他们没有什么不喜欢这个项目(37.6%)，近三分之一(31.9%)的人表示不喜欢该计划，因为它似乎过于支持疫苗接种，而且其他成员也表现得很粗鲁(7.1%)。那些持保守政治观点的人不太可能对这个群体感到满意(P=.04)。
结论：Facebook小组代表了让参与者参与改善COVID-19疫苗接种的一种可接受的方式。Facebook小组的某些方面可能会在未来的迭代中得到改进。
