COVID-19 vaccine knowledge, attitudes, perceptions and uptake among healthcare workers of Pune district, Maharashtra

Background: Healthcare workers play a vital role in vaccine promotion and acceptance through community dialogue, education, and myth-busting. Vaccinated healthcare workers will likely recommend the vaccine to their families and community.

Investigation of SARS-CoV-2 antibodies in healthcare workers developed due to COVID-19 vaccines

Background: Extra obligations and measures are required for health care workers (HCWs) due to COVID-19. Objectives:This study aims to investigate anti-S1 IgG response after inactive SARS-CoV-2 vaccine and the factors affecting it for HCWs.

What Went Wrong with the IMMUNI Contact-Tracing App in Italy? A Cross-Sectional Survey on the Attitudes and Experiences among Healthcare University Students.

The adoption of digital contact-tracing apps to limit the spread of SARS-CoV-2 has been sup-optimal, but studies that clearly identify factors associated with the app uptake are still limited. In April 2021, we administered a questionnaire to healthcare university students to investigate their attitudes towards and experiences of the IMMUNI app. A multivariable logistic regression model was built to identify app download predictors. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated. We surveyed 247 students. Most respondents (65.6%) had not downloaded IMMUNI, reporting as the main reason the perceived app uselessness (32.7%). In the multivariable analysis, being advised to use the app (aOR: 3.21, 95%CI: 1.80-5.73), greater fear of infecting others (aOR: 1.50, 95%CI: 1.01-2.23), and greater trust in the institutional response to the emergency (aOR: 1.33, 95%CI: 1.00-1.76) were positively associated with the outcome, whereas greater belief in the "lab-leak theory" of COVID-19 was a negative predictor (aOR: 0.75, 95%CI: 0.60-0.93). Major technical issues were reported by app users. Targeted strategies aimed at improving awareness of digital health applications should be devised. Furthermore, institutions should invest in the development of these technologies, to minimize technical issues and make them accessible to the entire population.

"Immuni" and the National Health System: Lessons Learnt from the COVID-19 Digital Contact Tracing in Italy.

Since the early stage of the current pandemic, digital contact tracing (DCT) through mobile phone apps, called "Immuni", has been introduced to complement manual contact tracing in Italy. Until 31 December 2021, Immuni identified 44,880 COVID-19 cases, which corresponds to less than 1% of total COVID-19 cases reported in Italy in the same period (5,886,411). Overall, Immuni generated 143,956 notifications. Although the initial download of the Immuni app represented an early interest in the new tool, Immuni has had little adoption across the Italian population, and the recent increase in its download is likely to be related to the mandatory Green Pass certification for conducting most daily activities that can be obtained via the application. Therefore, Immuni failed as a support tool for the contact tracing system. Other European experiences seem to show similar limitations in the use of DTC, leaving open questions about its effectiveness, although in theory, contact tracing could allow useful means of "proximity tracking".

Detroit City Mass Vaccination Site Template

Study Objective: In 2020, the city of Detroit was impacted by the COVID-19 pandemic, with over 162,000 reported diagnosed cases and 4,800 deaths. In response to anticipated availability of a vaccine, the Detroit Health Department developed plans for a drive-through mass vaccination site to help distribute the vaccine to the city’s population. We describe the Detroit City Mass Vaccination Site and its methods of recruitment, enrollment, site selection, and logistics. Discussion: Initial recruitment for vaccination was through traditional media means as well as the city of Detroit’s website. Interested individuals were instructed to call a dedicated scheduling line in addition to separate numbers for general inquiries and SMS based inquiries for vaccination sites. Individuals were provided appointments on the hour for both doses at the appropriate interval during the initial conversation. Methods: The TCF Conference Center was selected due to its central location, vicinity to the city’s vaccine storage site, capacity for large number of vehicles, protection from the elements, and availability. As vehicles arrived for appointments, they went through multiple checkpoints for confirmation of appointment and consent for treatment. Detroit police traffic control units aided with traffic-flow and vehicles were queued into two floors with a total of 27 lanes. On-site pharmacy was responsible for drawing, preparation, and delivery of vaccine doses to each lane. Once vehicles were confirmed for appointment and consent reviewed the vaccine was administered and vehicles remained in line for an observation period. Vaccine administration was documented on a CDC Vaccination Card and consent form was delivered to data entry workers from the Detroit Health Department for entry into the Michigan Care Improvement Registry (MCIR). On-site EMS supervisor, EMS teams, and an on-site physician and were available for medical response. After observation, vehicles were directed by security for egress. Results: To date, the TCF Center Mass Vaccination site accounts for over 220,000 doses administered with 62.0% of those doses given to individuals identifying as Black/African American, 31.9% identify as White and 6.0% identifying as another race. Conclusion: As vaccination studies showed promise for efficacy, the City of Detroit developed and implemented a mass vaccination site to help to mitigate the impact of COVID-19 on the city. Multiple public and private partners assisted in the effort. While only a piece of the necessary response, to date we have provided in excess of 250,000 doses of vaccine and this model has proven effective at providing mass vaccination while the population remains vaccine limited.
