Many brands have launched pandemic-themed advertising campaigns, aiming to build rapport with their customers in this unprecedented moment. Yet it is challenging for brands to know how to communicate efficiently. To fill this gap, the current research aims to provide a systematic framework that could guide advertisers in designing pandemic-themed advertisements to stimulate consumer engagement on social media by examining the role of values in context-specific brand communications. In particular, we analyze a large corpus of 286 brand YouTube videos posted between the onset of the COVID-19 and the fall of 2020 through a combination of qualitative induction, coding, and big data analytics. The results demonstrate that brands can incorporate various values in their brand communications when the world is combating a victim crisis like the current pandemic. Our findings reveal that hedonism, universalism, conformity, security, and tradition values positively predict consumer engagement (i.e., commenting), whereas stimulation value negatively predicts consumer commenting. We develop a new type of victim crisis - omnipresent victim crisis - and offer a theorization of this sub-type of victim crisis to delineate the pandemic or crises alike (e.g., environmental issues) for future research. We further highlight the role of value embodiment in crisis communication and advertising literature and offer rich theoretical and practical implications.

Sequential immunization is one of the special means to solve the shortage of vaccines, respond to SARS-CoV-2 variants and improve the efficacy of vaccines in the current pandemic period. This article mainly reviewed five sequential immunization strategies using the vaccines authorized by World Health Organization: priming with inactivated vaccine and boosting with recombinant protein vaccine, vector vaccine or mRNA vaccine;priming with vector vaccine and boosting with mRNA vaccine;prime-boost immunization with mRNA vaccines produced by different manufactures. Results of the related studies showed that heterologous sequential immunization strategies were safe and effective, and higher immunogenicity and efficacy could be achieved by sequential immunization. In addition, sequential immunization could provide certain protective effects against SARS-CoV-2 variants.

Background: COVID-19 is an emerging infectious disease that is extremely difficult to prevent and control. Community prevention and control is an important way to curb the spread of the pandemic. The community workers for containing COVID-19 are the main body of COVID-19 prevention and control force, undertaking tasks such as registering the brief health-related information of persons entering and leaving the community, governing the community environment, and publicizing knowledge pertaining to COVID-19 prevention. However, their COVID-19-related knowledge level and specific work tasks are not clear. We performed a survey concerning their structure, COVID-19-related knowledge, attitudes, and work characteristics, providing information for improving the mechanism of community-based regular epidemic prevention and control. Objective: To investigate the structure, COVID-19-related knowledge, attitudes, and work characteristics of the community COVID-19 containment team, to provide a scientific basis for optimizing the allocation of human resources for community COVID-19 containment and for promoting the popularizing of COVID-19-related knowledge. Methods: A self-designed questionnaire was used to conduct a survey with community workers for containing COVID-19 selected from five streets in Baoan District, Shenzhen from March 12 to 21, 2020 by convenience sampling, for collecting their demographics, COVID-19-related knowledge and attitudes. Results: Of the 756 workers, 753(99.6%) who completed the questionnaire effectively were included for final analysis, including 552 men(73.3%) and 201 women(26.7%), with 18-35 age group〔61.1%(460/753)〕 or those with high school or specialized school〔31.2%(235/753)〕attainment accounting for the largest percentage. Three aspects concerning COVID-19 containment obtained the highest awareness rates:required days for continuing to monitor self-health after discharge〔73.3%(552/753)〕, incubation period〔44.6%(336/753)〕, and criteria for releasing from quarantine〔39.0%(294/753)〕. Men had a higher awareness rate of main symptoms of COVID-19 but had lower awareness rates of the class of COVID-19 as an infectious disease, kinds of disinfectants for deactivating the SARS-CoV-2 virus, the follow-up period and revisit time as well as number of self-health monitoring days(P0.05). Younger age was associated with lower awareness rates of the class of COVID-19 as an infectious disease, and incubation period of COVID-19, but higher awareness rate of COVID-19 main symptoms(P0.05). Education level was associated with higher or lower awareness rates of the aspects concerning COVID-19 related information(P0.05) except the awareness rate of transmission routes of COVID-19. Occupation was associated with significant differences in the awareness rates of the class of COVID-19 as an infectious disease and number of self-health monitoring days(P0.05). Higher annual household income per capita was associated with higher awareness rate of number of self-health monitoring days(P0.05). Poorer self-rated health was associated with lower awareness rate of incubation period of COVID-19 but higher awareness rate of number of self-health monitoring days(P0.05). The average score for the attitudes toward COVID-19 was(46.07±5.77). The average number of working days for containing COVID was (42.77±14.87).Those worked for 8-12 hours per working day accounting for the largest percentage〔51.5%(388/753)〕. 498(66.1%) participated in the community-based COVID-19 containment consisting of monitoring, screening and treatment. And 240(31.9%)played a role in undertaking at least 3 tasks. Conclusion: The structure of these community teams for containing COVID-19 was not appropriate, with a low awareness rate of information about containing COVID-19, and negative attitudes towards the pandemic. Their demographics showed different associations with different aspects of COVID-19-related information. Moreover, the COVID-19 containment may be long-term, arduous and complicated. Against the backdrop of regul r COVID-19 containment in the community, the allocation of the workers for pandemic containment should be optimized, their tasks should be adjusted appropriately, and COVID-19 containment trainings for them should be strengthened.
