Development of a live attenuated MCF vaccine has prompted research into its use in communities at risk. This study reports results from the first utilisation of the MCF vaccine in locally-owned cattle under field conditions. The study involved a primary two-dose course vaccination of 1634 cattle, followed a year later, by boost vaccination of 385 of these cattle. It aimed to: (a) evaluate the antibody response to a two-dose AlHV-1 primary vaccination course, including initial response, antibody levels after one year, and clinical events post-vaccination; (b) assess how factors like age, reproductive status, body condition, and breed influence the initial response; and (c) compare antibody responses to single- and two-dose booster protocols one year after primary vaccination. Analyses were carried out using linear mixed-effects models and paired t-tests. Clinical incidents were reported in 11/1634 cattle vaccinated during the primary course and in 0/385 cattle during the boost regimens. The primary vaccination resulted in a 9-fold increase in comparison to pre-vaccination antibody levels and the response was consistent across animals of different ages, reproductive statuses and body conditions. While antibody levels declined 11 months after primary vaccination, they remained high, and a single-dose booster vaccination was sufficient to elicit a strong immune response, with only marginal increases after a second booster. The study provides evidence of high immunogenicity and low incidences of clinical events of the vaccine in cattle across individual host factors and immunologically vulnerable groups, under prevailing environmental conditions. It also indicates the utility of a single-dose booster regimen.

Understanding the ethical concerns related to the use of social media in this capacity are important. The purpose of this study is to identify ethical concerns of using fictional stories to share information and emotions about the HPV vaccine on social media, ultimately to influence parents on their decision to vaccinate their child.</p><p><strong>Methods: </strong>We conducted a cross-sectional survey with researchers in the fields of health communication, cancer prevention, social media, and public health ethics from October to December 2021. Respondents were presented with a fictional story that consisted of seven connected vignettes about the HPV vaccine. For each vignette, respondents were asked to rate the potential benefits and risk, as well as the potential for ethical concerns of using the fictional narrative style to share information about the HPV vaccine. Descriptive statistics summarized responses, and qualitative data were analyzed thematically.</p><p><strong>Results: </strong>On average, respondents (n = 41) perceived more benefits than risks when it comes to 1) using social media for health education generally and 2) using a story with connected vignettes for vaccine communication. The vignettes prioritizing vaccine hesitancy, positive emotion, and health equity were seen as having the most potential benefit, while the vignettes highlighting vaccine confidence and skepticism were seen as having the most potential risk. Overall, respondents felt there were several ethical concerns of note - persuasion was the most common (15 % of respondents) followed by deception (9 %) and manipulation (8 %). Qualitative data highlighted the importance of transparency and trust to avoid ethical violations and negative outcomes.</p><p><strong>Conclusions: </strong>Ethical concerns exist when using fictional stories to share health information on social media, particularly as new online technologies make it harder to tell fact from fiction. Practical and actionable recommendations for researchers must be developed, defining a range of ethical responsibilities.</p>","PeriodicalId":94264,"journal":{"name":"Vaccine","volume":" ","pages":"126575"},"PeriodicalIF":0.0,"publicationDate":"2024-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142815441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
