Published: January 2023   Journal: About Journal of Pediatric Nursing
This study explored factors associated with parents' attitudes and intentions to seek information about the COVID-19 vaccine for their children (ages 0–18) and intentions to vaccinate their age-eligible children. As part of an anonymous online cross-sectional survey, parents' vaccine attitudes, COVID-19 vaccine intentions for their children, health literacy, health numeracy, and sociodemographic variables were assessed. Multivariable ordered logistic regression models identified factors associated with parents' COVID-19 vaccine intentions for their children.

Published: January 2023   Journal: Vaccine

Few studies have assessed the impact of the coronavirus disease 2019 (COVID-19) pandemic on immunization coverage for adolescents, and little is known about how coverage has changed throughout the pandemic. This study aimed to: (1) assess the change in coverage for school-based vaccines in Alberta, Canada resulting from the pandemic; (2) determine whether coverage differed by geographic health zone and school type; and (3) ascertain whether coverage has returned to pre-pandemic levels. Using a retrospective cohort design, this study used administrative health data to compare coverage for human papillomavirus (HPV) and meningococcal conjugate A, C, Y, W-135 (MenC-ACYW) vaccines between pre-pandemic (2017–2018 school year) and pandemic (2019–2020 and 2020–2021 school years) cohorts (N = 289,420). Coverage was also compared by health zone and authority type. The 2019–2020 cohort was followed over one year to assess catch-up.

Published: January 2023   Journal: Frontiers in Pediatrics

This study has three aims: to elucidate determinants associated with COVID-19 vaccine uptake in children and the association with parental vaccination; to compare rates of PCR-positive SARS-CoV-2 results between vaccinated and unvaccinated children; to estimate the rate of parental COVID-19 vaccination and its association with the vaccination rate of their children. It performed a retrospective chart review of all children aged 5–11 years registered at a central district in Israel from November 21st, 2021 to April 30th, 2022, and characterized COVID-19 vaccinated vs. unvaccinated individuals. Data retrieved from the electronic medical files included: demographics [age, gender, sector, socioeconomic status (SES)]; COVID-19 vaccination (first and second doses) and influenza vaccination status; co-morbidities; and parental vaccinations for COVID-19. It divided the population into three distinct demographic groups: non-ultra-orthodox Jews (43,889 children), ultra-orthodox Jews (13,858 children), and Arabs (4,029 children).

The objective of this study is to assess the frequency and severity of adverse events following immunization (AEFI) in Indian children aged 5–17 years who received the Pfizer-BioNTech mRNA COVID-19 vaccine, as well as to investigate for predictors of AEFI. To examine AEFI following the first and second doses of Pfizer’s vaccine, semi-structured questionnaires were distributed as Google forms at Indian schools in Saudi Arabia. The 385 responses included 48.1% male and 51.9% female children, with 136 responses of children aged 5–11 years (group A) and 249 responses from children aged 12–17 years (group B). Overall, 84.4% of children had two shots. The frequency of AEFI was reported to be higher after the first dose than after the second (OR = 2.12, 95% CI = 1.57–2.86). The reported AEFIs included myalgia, rhinitis, local reaction with fever, a temperature of 102 °F or higher, and mild to moderate injection site reactions. While group B frequently reported multiple AEFIs, group A typically reported just one. Local reaction with low grade fever was more frequently reported in group B after the first dose (24.1%) and second dose (15.4%), while local reaction without low grade fever was most frequently observed in group A after the first (36.8%) and second dose (30%). Only prior COVID-19 infection (OR = 2.98, 95% CI = 1.44–6.2) was associated with AEFI after the second dose in the study sample, whereas male gender (OR = 1.71, 95% CI = 1.13–2.6) and prior COVID-19 infection (OR = 2.95, 95% CI = 1.38–6.3) were predictors of AEFI after the first dose. Non-serious myocarditis was reported by only one child. According to the analysis conducted, the Pfizer’s mRNA COVID-19 vaccination was found to be safe in Indian children.

Published: January 2023   Journal: Vaccine
Research suggest prenatal vaccination against coronavirus disease-19 (COVID-19) is safe. However, previous studies utilized retrospectively collected data or examined late pregnancy vaccinations. This study investigated the associations of COVID-19 vaccination throughout pregnancy with delivery and neonatal outcomes. It included 1,794 mother-neonate dyads enrolled in the Generation C Study with known prenatal COVID-19 vaccination status and complete covariate and outcome data. It used multivariable quantile regressions to estimate the effect of prenatal COVID-19 vaccination on birthweight, delivery gestational age, and blood loss at delivery; and Poisson generalized linear models for Caesarean delivery (CD) and Neonatal Intensive Care Unit (NICU) admission.

Published: January 2023   Journal: Vaccine

A worldwide COVID-19 mass vaccination campaign targeting adults was launched in late December 2020. Subsequently, the Comirnaty (BNT162b2) vaccine was recommended for children aged 12–15 years in May 2021. In Norway, only one dose of the Comirnaty vaccine was recommended to children aged 12–15 years. Vaccination was not recommended for children who had been infected with SARS-CoV-2. In line with findings in older age groups, the most prevalent adverse events after vaccination that have been reported in 12- to 15-year-old adolescents are injection site pain (in 79 to 86 % of participants), fatigue (in 60 to 66 %), and headache (in 55 to 65 %). Adolescents aged 12–17 years have been found to have a moderately higher risk of adverse reactions than adults. For new vaccines, clinical trials typically collect data on commonly recognized adverse events and safety profiles. However, questions about the menstrual cycle have not been included in clinical studies. A significant number of reports on menstrual disturbances after COVID-19 vaccination have been registered in spontaneous adverse events surveillance systems in several countries (USA, UK, Norway, the Netherlands).

Millions of children have tested positive for SARS-CoV-2, and over 1000 children have died in the US. However, vaccination rates for children 5 to 11 years old are low. Starting in August 2020, we conducted a prospective SARS-CoV-2 household surveillance study in Spanish and English-speaking households in New York City and Utah. From October 21 to 25, 2021, we asked caregivers about their likelihood of getting COVID-19 vaccine for their child, and reasons that they might or might not vaccinate that child. We compared intent to vaccinate by site, demographic characteristics, SARS-CoV-2 infection detected by study surveillance, and parents’ COVID-19 vaccination status using Chi-square tests and a multivariable logistic regression model, accounting for within-household clustering.

Published: December 2022   Journal: Vaccine

The vaccination of children and adolescents for the prevention of Covid-19 is important to:decrease in deaths and hospitalizations, prevent multisystem inflammatory syndrome, avoid long-term complications and decrease the suspension of on-site classes. Despite of these benefits, some studies have shown that some caregivers are still hesitancy. This is a voluntary and anonymous online survey conducted from November 17 to December 14, 2021, in Brazil, through a free-of-charge platform with a link provided on social networks. A bivariate analysis was conducted with the independent variables, with vaccine hesitancy as the outcome variable, and a multivariate logistic model was used to calculated adjusted odds ratios.
