我们评估了马萨诸塞州COVID-19疫苗抽签是否增加了疫苗接种。我们分析了来自疾病控制和预防中心COVID-19疫苗追踪器的数据，以确定在2021年3月6日至7月31日的研究期间，在马萨诸塞州、康涅狄格州、罗得岛、新泽西和佛蒙特州至少接种了第一剂COVID-19疫苗或完全接种了疫苗的18至64岁成年人的总数。五个州中的每一个都提供了148天的疫苗接种人数累积每日报告，包括740个州日的总样本量。我们使用负二项回归模型进行了多变量的州日水平差异（DID）回归，该模型比较了马萨诸塞州与四个地理上相邻的没有彩票的比较州在马萨诸塞州疫苗彩票宣布（2021年6月15日）之前和之后的结果变化。我们的分析控制了从美国社区调查中获得的关键州一级特征以及日固定效应，以捕捉结果的长期趋势。与其他州相比，马萨诸塞州COVID-19疫苗抽签与18至64岁成年人完全接种或至少接种一剂疫苗的人数显著增加无关[全剂量，发病率比（IRR）：1.04，95%置信区间（CI）：0.97至1.11，P > 0.05;至少接种一剂，IRR：0.99，95% CI：0.93 ~ 1.06，P > 0.05]。没有足够的证据得出结论，马萨诸塞州COVID-19疫苗抽签与成人COVID-19疫苗接种人数增加有关。
We evaluated whether the Massachusetts COVID-19 vaccine lottery increased vaccine uptake. We analyzed data from the Centers for Disease Control and Prevention COVID-19 Vaccine Tracker to identify total number of adults aged 18 to 64 who received at least first dose of the COVID-19 vaccine or who were fully vaccinated in Massachusetts, Connecticut, Rhode Island, New Jersey, and Vermont during the study period of March 6 –July 31, 2021. Each of the five states contributed 148 days of a daily report on cumulative number of vaccinated people, comprising 740 state-days as the total sample size. We conducted multivariable, state-day level difference-in-differences (DID) regression using a negative binomial regression model that compared the change in outcomes for Massachusetts to those of four geographically adjacent comparison states without the lotteries, before and after the Massachusetts vaccine lottery announcement (June 15, 2021). Our analyses controlled for key state-level characteristics obtained from the American Community Survey as well as day fixed-effects to capture secular trends in the outcomes. Massachusetts COVID-19 vaccine lottery was not associated with a significant increase in the number of adults aged 18 to 64 who were fully vaccinated or received at least one dose of the vaccine, compared with other states [Full dose, incidence rate ratio (IRR): 1.04, 95% confidence interval (CI): 0.97 to 1.11, P > 0.05; At least one dose, IRR: 0.99, 95% CI: 0.93 to 1.06, P > 0.05]. There was insufficient evidence to conclude that Massachusetts COVID-19 vaccine lottery was associated with increased number of adult COVID-19 vaccinations.
