Project description:IntroductionVaccinating children against COVID-19 protects children's health and can mitigate the spread of the virus to other community members.ObjectiveThe primary objective of this study was to use a socio-ecological perspective to identify multi-level factors associated with US parents' intention to vaccinate their children.MethodsThis study used a longitudinal online cohort. Multinomial logistic regression models assessed socio-ecological predictors of negative and uncertain child COVID-19 vaccination intentions compared to positive intentions.ResultsIn June 2021, 297 parents were surveyed and 44% reported that they intended to vaccinate their children while 25% expressed uncertainty and 31% did not intend to vaccinate their children. The likelihood of reporting uncertain or negative intention, compared to positive intention to vaccinate their children was higher among parents who had not received a COVID-19 vaccination and those who did not have trusted information sources. Parents who talked to others at least weekly about the COVID-19 vaccine were less likely to endorse uncertain compared to positive vaccine intentions (aRRR: 0.44; 95% CI: 0.20-0.93). A sub-analysis identified that parents had significantly higher odds of intending to vaccinate older children compared to younger children (children ages 16-17 years v. 0-4 years OR: 2.01, 95% CI: 1.05-3.84). An additional sub-analysis assessed the stability of parents' intention to vaccinate their children between March 2021 and June 2021 (N=166). There was transition within each intention group between the study periods; however, symmetry and marginal homogeneity test results indicated that the shift was not statistically significant. Parents expressing uncertainty in March 2021 were the most likely to change their intention, with 24% transitioning to positive intention and 23% to negative intention in June 2021.ConclusionStudy findings suggest that programs to promote vaccination uptake should be dyadic and work to promote child and parent vaccination. Peer diffusion strategies may be particularly effective at promoting child vaccination uptake among parents expressing uncertainty.
Project description:Parent vaccine hesitancy (PVH) remains a significant public health concern, particularly emphasized during the COVID-19 pandemic. This study investigates PVH among parents of children with various psychiatric and neurodevelopmental conditions, such as attention deficit hyperactivity disorder (ADHD), anxiety disorders, and behavioral disturbances, extending previous research focused on autism spectrum disorder (ASD). We examined PVH in children aged 5-11 years with psychiatric and behavioral disorders excluding ASD. A cross-sectional questionnaire-based analysis was conducted in Qatar, involving 244 parents of neurodiverse children and 245 parents of neurotypical children as controls. The Parent Attitudes about Childhood Vaccines (PACV) survey assessed PVH. Results indicated a significantly higher prevalence of vaccine hesitancy among parents of children with psychiatric disorders (54.1%, 95% CI [47.8%, 60.4%], n = 132) compared to controls (11.7%, 95% CI [7.5%, 16.0%], n = 26), p < .001. The PACV total score was significantly higher in parents of children with a mental disorder. Higher education among parents and lower PACV scores significantly influenced the intent to vaccinate against COVID-19. Tailored interventions by child and adolescent mental healthcare professionals, such as harnessing artificial intelligence to fight disinformation, are crucial to addressing vaccine hesitancy, enhancing acceptance, and improving outcomes for children with psychiatric disorders.
Project description:As the global vaccination mass campaign against COVID-19 extended to children aged 5 to 11 years, some parents remained hesitant about their children being administered the vaccine despite data supporting its safety. Parent vaccine hesitancy (PVH) may have predisposed certain groups of children, particularly those with autism spectrum disorder (ASD), to COVID-19 when other neurotypical children would have been vaccinated. We investigated the current PVH in 243 parents of children with ASD and 245 controls using the Parent Attitudes about Childhood Vaccines (PACV) scale. The study was conducted in Qatar from May to October 2022. Overall, 15.0% [95% CI 11.7%; 18.3%] of parents were vaccine-hesitant, with no difference (p = 0.054) between groups (ASD children [18.2%] vs. controls [11.7%]). The only sociodemographic factor associated with higher vaccine hesitancy was being a mother (as compared to being a father). The COVID-19 vaccine receipt rate at the time of the study did not differ between ASD (24.3%) and non-ASD groups (27.8%). Around two-thirds of parents of children with ASD refused or were unsure about vaccinating their children against COVID-19. We found that the intent to vaccinate against COVID-19 was higher in parents who were married and in those with a lower PACV total score. Continued public health efforts are needed to address vaccine hesitancy among parents.

Project description:ObjectivesThe chronic conditions and functional limitations experienced by children with medical complexity (CMC) place them at disproportionate risk for COVID-19 transmission and poor outcomes. To promote robust vaccination uptake, specific constructs associated with vaccine hesitancy must be understood. Our objective was to describe demographic, clinical, and vaccine perception variables associated with CMC parents' intention to vaccinate their child against COVID-19.MethodsWe conducted a cross-sectional survey (June-August 2021) for primary caregivers of CMC between ages 5 to 17 at an academic medical center in the Midwest. Multivariable logistic regression examined associations between vaccination intent and selected covariates.ResultsAmong 1330 families, 65.8% indicated vaccination intent. In multivariable models, demographics had minimal associations with vaccination intent; however, parents of younger children (<12 years) had significantly lower adjusted odds of vaccination intent (adjusted odds ratio [95% confidence interval]: 0.26 [0.17-0.3]) compared to parents of older children (≥12 years). CMC with higher severity of illness, ie, those with ≥1 hospitalization in the previous year (versus none) or >1 complex chronic condition (vs 1), had higher adjusted odds of vaccination intent (1.82 [1.14-2.92] and 1.77 [1.16-2.71], respectively). Vaccine perceptions associated with vaccine intention included "My doctor told me to get my child a COVID-19 vaccine" (2.82 [1.74-4.55]); and "I'm concerned about my child's side effects from the vaccine" (0.18 [0.12-0.26]).ConclusionsOne-third of CMC families expressed vaccine hesitation; however, constructs strongly associated with vaccination intent are potentially modifiable. Pediatrician endorsement of COVID-19 vaccination and careful counseling on side effects might be promising strategies to encourage uptake.
Project description:BackgroundThis research was conducted following the FDA's approval of the COVID-19 vaccine for children aged 5 to 11. Our study aimed to evaluate parents' intentions regarding vaccinating their children in response to the pandemic situation. This period was crucial for understanding parents' initial reactions to health authority recommendations.MethodsThis descriptive cross-sectional study was conducted with 940 parents. The data were obtained using the Personal Information Form, the COVID-19 Anxiety Scale, and the Scale of Attitudes Towards COVID-19 Vaccine. Descriptive data analysis involved calculating frequency, percentage, mean, and standard deviation values. We employed Student's t-test, one-way ANOVA tests for analysis. Additionally, various characteristics were analyzed using the two-way logistic regression method.ResultsIn the study, 85.1% of the parents reported having received the COVID-19 vaccine themselves. However, only 20% stated they would accept the COVID-19 vaccine for their children. The intention to vaccinate their children was influenced by factors such as the parent's age, level of COVID-19 anxiety, vaccination status, and knowledge about the COVID-19 vaccine.ConclusionDespite the FDA's declaration, it was determined that more than two-thirds of parents were hesitant about the COVID-19 vaccine for their children.
Project description:ObjectiveThe success of COVID-19 vaccination programs relies on community attitudes, yet little is known about parents' views. We aimed to explore the reasons behind Australian parents' vaccine intentions for themselves and for their children.MethodThis mixed methods study relates to Wave 13 (January 2021) of a longitudinal study of Australian parents' experiences during COVID-19 and contained 1094 participants (83% mothers). We used multinomial logistic regression to understand demographic predictors of vaccine intention, and a descriptive template thematic analysis to analyse open-ended questions about parents' reasons for vaccine intentions for themselves and their children.Results64% of Australian parents intend on vaccination, 26% are unsure and 9% intend to decline; 48% intend to vaccinate their children, 38% are unsure, and 14% intend to decline. Relative to those intending to vaccinate, parents unsure (OR = -0.63, 95% CI: 0.46, -0.84, p = .002) or not intending (OR = -0.41, 95% CI: 0.24, 0.67 p < .001) to vaccinate were more likely to have lower trust in doctors. Similar predictors emerged for parents who did not intend to vaccinate their children (OR = 0.47, 95% CI: 0.31, 0.70, p < .001). Qualitative data indicated that many parents had not made a firm decision, including a lack of alignment between intentions and reasons. For example, parents who said 'yes' to vaccination, often then expressed hesitance and a focus on risks in their written response. Reasons for hesitancy for themselves included concerns about testing, side effects, and long-term outcomes. Similar themes were present for children, but parents expressed a strong desire to protect their children, and an eagerness for health information.ConclusionBased on prior research and the themes identified here, a multipronged campaign that includes education/promotion, good access to vaccines and role models, is likely to support parents to make informed decisions regarding COVID-19 vaccination.
Project description:Purpose: This study aims to characterize the early innate and adaptive responses induced by SARS-CoV-2 infection in children and adults over time up to 8 weeks post symptoms onset (POS). We report the gene signature of COVID-19 over the course of the disease in both age groups. The kinetic of infection was divided in 5-time intervals according to the calculated days POS: interval 1 (0-5), interval 2 (6-14), interval 3 (15-22), interval 4 (23-35), and interval 5 (36-81). Methods: RNA extraction was performed automatically via the PAXgene Blood miRNA Kit and the QIAcube instrument (Qiagen) following the manufacturer’s protocol. RNA concentration and quality were assessed by using the Qubit instrument (Invitrogen) and the Agilent 2100 Bioanalyzer, respectively. The Stranded Total RNA Ribo-Zero Plus kit from Illumina was used for the library preparation with 100 ng of total RNA as input. Library molarity and quality were assessed with the Qubit and Tapestation using a DNA High sensitivity chip (Agilent Technologies). Libraries were pooled at 2 nM for clustering and sequenced on an Illumina HiSeq 4000 sequencer for a minimum of 30 million single-end 100 reads per sample. Main results: (I) we observed an antiviral-IFN-signature and innate-cell-activation within the first 5 days post symptoms onset (POS), while genes associated with CD4 T-cell responses, plasma cells and immunoglobulin were upregulated in both age groups during the first two weeks POS, indicative of SARS-CoV-2-specific adaptive immune responses; (II) in adults, genes associated with IFN antiviral responses and activated dendritic cells were maintained during the second week of disease, and subsided only after 14 days. By contrast, those transcriptome changes subsided already after 5 days in children.
Project description:BACKGROUND. Coronavirus disease 2019 (COVID-19) is more benign in children compared with adults for unknown reasons. This contrasts with other respiratory viruses where disease manifestations are often more severe in children. We hypothesize that a more robust early innate immune response to SARS coronavirus 2 (SARS-CoV-2) protects against severe disease. METHODS. Clinical outcomes, SARS-CoV-2 viral copies, and cellular gene expression were compared in nasopharyngeal swabs obtained at the time of presentation to the emergency department from 12 children and 27 adults using bulk RNA sequencing and quantitative reverse-transcription PCR. Total protein, cytokines, and anti–SARS-CoV-2 IgG and IgA were quantified in nasal fluid. We used a subset of 21 samples for RNAseq analysis. RESULTS. SARS-CoV-2 copies, angiotensin-converting enzyme 2 (ACE2), and TMPRSS2 gene expression were similar in children and adults, but children displayed higher expression of genes associated with IFN signaling, NLRP3 inflammasome, and other innate pathways. Higher levels of IFN-α2, IFN-γ, IP-10, IL-8, and IL-1β protein were detected in nasal fluid in children versus adults. Children also expressed higher levels of genes associated with immune cells, whereas expression of those associated with epithelial cells did not differ in children versus adults. Anti–SARS-CoV-2 IgA and IgG were detected at similar levels in nasal fluid from both groups. None of the children required supplemental oxygen, whereas 7 adults did (P = 0.03); 4 adults died. CONCLUSION. These findings provide direct evidence of a more vigorous early mucosal immune response in children compared with adults and suggest that this contributes to favorable clinical outcomes.
