BACKGROUND Seasonal influenza vaccination (SIV) coverage among young children remains low worldwide. Mobile social-networking applications such as WhatsApp Messenger are promising tools for health interventions. OBJECTIVE This was a preliminary study to test the effectiveness and parental acceptability of social-networking intervention that sends weekly vaccination reminders and encourages exchange of SIV-related views and experience among mothers via WhatsApp discussion groups for promoting childhood SIV. The second objective was to examine the effect on mothers’ decision-making for childhood SIV of additionally introducing time pressure for vaccination decision-making using countdowns of the recommended vaccination timing. METHODS Mothers of child(ren) aged 6-72 months were randomly allocated to Control, or one of two social-networking Intervention groups receiving vaccination reminders with (SNI/+TP) or without (SNI/-TP) a time pressure component via WhatsApp discussion groups at a ratio of 5:2:2. All participants first completed a baseline assessment. Both the SNI/-TP and SNI+TP groups subsequently received respective weekly vaccination reminders in Oct-Dec 2017, and participated in WhatsApp discussions about SIV moderated by a health professional. All participants completed a follow-up assessment in April-May 2018. RESULTS A total of 174 (84.9%, 174/205), 57 (71.3%, 57/80) and 60 (75.0%, 60/80) who were allocated into the Control, SNI/-TP and SNI/+TP, respectively, completed the outcome assessment. The social-networking intervention significantly promoted mothers’ self-efficacy for taking children for SIV (SNI/-TP: OR=2.69 (1.07-6.79); SNI/+TP: OR=2.50 (1.13-5.55)), but did not result in significantly improved children’s SIV uptake. Moreover, after adjusting for mothers’ working status, introducing additional time pressure reduced the overall SIV uptake in children of working mothers (OR=0.27 (0.10-0.77)) but significantly increased the SIV uptake among children of mothers without a full-time job (OR=6.53 (1.87-22.82)). Most participants’ WhatsApp posts were about sharing experience/views (52.1%, 226/434) of which 44.7% (101/226) were categorized as negative such as their concerns over vaccine safety/side effects and effectiveness. Though participants shared predominantly negative experience/views about SIV at the beginning of the discussion, the moderator was able to encourage the discussion of more positive experience/views and more knowledge/information. Most Intervention group participants indicated willingness to receive the same interventions (94.0%, 110/117) and recommend the interventions to other mothers (87.2%, 102/117) in future. CONCLUSIONS Online information support can effectively promote mothers’ self-efficacy for taking children for SIV but may not alone be sufficient to address maternal concerns over SIV to achieve a positive vaccination decision. However, the active involvement of health professionals in online discussions can shape positive discussions about vaccination. Time pressure on decision-making interacts with maternal work status, facilitating vaccination uptake among mothers who may have more free time job but having the opposite effect among busier working mothers.

Safety Surveillance

ObjectivesTo determine how soon after commencement of the seasonal influenza vaccination programme, the AusVaxSafety active vaccine safety surveillance system, currently in use across Australia, would have detected a safety signal had it been operating in 2010 when there was an unprecedented number of febrile seizures in young children associated with one specific influenza vaccine brand, Fluvax (CSL Biotherapies).DesignSimulation study.SettingWestern Australian vaccine influenza coverage and adverse event surveillance data.Outcome measuresSimulated solicited responses from caregivers who would have received an SMS survey about adverse events experienced following seasonal influenza vaccination of their children aged 6 months to <5 years.ParticipantsNone.ResultsWe estimated a >90% probability of a safety signal being detected by AusVaxSafety based on solicited reports for either fever or medical attendance at or before the week ending 28 March 2010, 3 weeks after the start of vaccine distribution. Suspension of the national paediatric influenza vaccination programme as a result of the passive adverse events surveillance operating at the time did not occur until 23 April 2010.ConclusionsActive vaccine safety surveillance leading to rapid detection of a safety signal would likely have resulted in earlier suspension of Fluvax from the vaccination programme, prevention of many febrile convulsions and maintenance of public confidence in influenza vaccination for young children.

Abstract Despite recommendations, few children aged 6–35 months in Thailand receive seasonal influenza vaccination. Using previously estimated incidence and vaccine effectiveness data from the period 2012–2014, we estimate that up to 121 000 medical visits could be prevented each year with 50% coverage and expanded recommendations to children aged &lt;5 years.

Abstract Background All aged individuals with a chronic condition and those with 65 and more years are at increased risk of severe influenza post-infection complications. There is limited research on cases averted by the yearly vaccination programs in high-risk individuals. The objective was to estimate the impact of trivalent seasonal influenza vaccination on averted hospitalizations and death among the high-risk population in Portugal. Methods The impact of trivalent seasonal influenza vaccination was estimated using vaccine coverage, vaccine effectiveness and the number of influenza-related hospitalizations and deaths. The number of averted events (NAE), prevented fraction (PF) and number needed to vaccinate (NVN) were estimated for seasons 2014/15 to 2016/17. Results The vaccination strategy averted on average approximately 1833 hospitalizations and 383 deaths per season. Highest NAE was observed in the ≥65 years population (85% of hospitalizations and 95% deaths) and in the 2016/17 season (1957 hospitalizations and 439 deaths). On average, seasonal vaccination prevented 21% of hospitalizations in the population aged 65 and more, and 18.5% in the population with chronic conditions. The vaccination also prevented 29% and 19.5% of deaths in each group of the high-risk population. It would be needed to vaccinate 3360 high-risk individuals, to prevent one hospitalization and 60,471 high-risk individuals to prevent one death. Conclusion The yearly influenza vaccination campaigns had a sustained positive benefit for the high-risk population, reducing hospitalizations and deaths. These results can support public health plans toward increased vaccine coverage in high-risk groups.

Objective.To measure support for seasonal influenza vaccination requirements among US healthcare personnel (HCP) and its associations with attitudes regarding influenza and influenza vaccination and self-reported coverage by existing vaccination requirements.Design.Between lune 1 and June 30, 2010, we surveyed a sample of US HCP (n = 1,664) recruited using an existing probability-based online research panel of participants representing the US general population as a sampling frame.Setting.General community.Participants.Eligible HCP who (1) reported having worked as medical doctors, health technologists, healthcare support staff, or other health practitioners or who (2) reported having worked in hospitals, ambulatory care facilities, long-term care facilities, or other health-related settings.Methods.We analyzed support for seasonal influenza vaccination requirements for HCP using proportion estimation and multivariable probit models.Results.A total of 57.4% (95% confidence interval, 53.3%–61.5%) of US HCP agreed that HCP should be required to be vaccinated for seasonal influenza. Support for mandatory vaccination was statistically significantly higher among HCP who were subject to employer-based influenza vaccination requirements, who considered influenza to be a serious disease, and who agreed that influenza vaccine was safe and effective.Conclusions.A majority of HCP support influenza vaccination requirements. Moreover, providing HCP with information about the safety of influenza vaccination and communicating that immunization of HCP is a patient safety issue may be important for generating staff support for influenza vaccination requirements.Infect Control Hosp Epidemiol 2012;33(3):213-221
