Published: October 2021   Journal: Acta Paediatrica

Vaccines are vital to ending the COVID-19 pandemic and we reviewed the data on vaccinating children, and including them in clinical trials, as most of the activity has focused on adults. English and Chinese databases, including PubMed, Elsevier Scopus, Web of Science, CNKI and CQVIP were searched, along with websites such as the World Health Organization and the University of Oxford.

Published: October 2021   Journal: Clinical Microbiology and Infection

Although coronavirus disease 2019 (COVID-19) may pose a lower risk of transmission to children than to adults, and schools have contributed little to infection among parents, many countries nevertheless implemented school closure. Following the emergence of the δ variant, which is more transmissible and globally dominant, the percentage of primary school-aged children testing positive has been increasing. Progressively, the circumstances have become more favourable to recommend vaccination of children because of the increased burden on children resulting from the new variants and the supporting evidence from the ongoing vaccine trials among school-aged children. The rollout of COVID-19 vaccines for children is an important step in reopening schools safely. Understanding parental intention to vaccinate their children against COVID-19 will help inform broad strategies to maximize immunization rates among children. This study was conducted in Hong Kong, a densely populated travel hub in southeast China where residents average 12.5 daily contacts

Vaccinating children (≤17 years old) is important for controlling the COVID-19 pandemic. As parents are primary decision makers for their children, this study aimed to assess parents’ perceptions and intentions regarding COVID-19 vaccination for their children, including for some underserved populations (e.g., newcomers, Indigenous peoples, and visible minority groups). It conducted a cross-sectional national survey of Canadian parents in December 2020, just as COVID-19 vaccines were approved for adults, to assess intention to vaccinate their children (aged 0–17 years) against COVID-19, perceptions of COVID-19 disease and vaccines, previous uptake of influenza and routine vaccines, and sociodemographic characteristics. Binomial logistic regression was used to assess the association between parents' lack of COVID-19 vaccination intention for their children and various independent variables.

Disproportionate impact of COVID-19 on racial and ethnic minority groups in the United States: a 2021 update

The COVID-19 pandemic’s disproportionate impact on people from some racial and ethnic groups in the U.S. persisted throughout 2021. Black, Latinx, and American Indian persons have been hospitalized and died at a higher rate than White persons consistently from the start of the pandemic. Early data show that hospitalization and mortality rates for Black, Latinx, and American Indian children are higher than White children in a worrying trend. The pandemic has likely worsened the gaps in wealth, employment, housing, and access to health care: the social determinants of health that caused the disparities in the first place. School closures will have a long-lasting impact on the widening achievement gaps between Black and Latinx students and White students. In the earlier vaccination phase, Black and Latinx persons were being vaccinated at a lower rate than their proportion of cases due to vaccine hesitancy, misinformation, and barriers to access. Vaccine hesitancy rates among these groups have since decreased and are now comparable to White persons. Aggregated data make it challenging to paint a picture of the actual impact of COVID-19 on Asian Americans as they are a diverse group with significant disparities.

Vaccines against COVID-19 are likely to be approved for children under 12 years in the near future. Understanding vaccine hesitancy in parents is essential for reaching herd immunity. A cross-sectional survey of caregivers in 12 emergency departments (ED) was undertaken in the U.S., Canada, and Israel. This study compared reported willingness to vaccinate children against COVID-19 with an initial survey and post-adult COVID-19 vaccine approval. Multivariable logistic regression models were performed for all children and for those <12 years. A total of 1728 and 1041 surveys were completed in phases 1 and 2, respectively. Fewer caregivers planned to vaccinate against COVID-19 in phase 2 (64.5% and 59.7%, respectively; p = 0.002). The most significant positive predictor of willingness to vaccinate against COVID-19 was if the child was vaccinated per recommended local schedules. Fewer caregivers plan to vaccinate their children against COVID-19, despite vaccine approval for adults, compared to what was reported at the peak of the pandemic. Older caregivers who fully vaccinated their children were more likely to adopt vaccinating children. This study can inform target strategy design to implement adherence to a vaccination campaign.
Adolescent consent to COVID-19 vaccination: the need for law reform

Published: September 2021   Journal: Public Health Reports
With the US Food and Drug Administration’s (FDA’s) emergency use authorization of the Pfizer-BioNTech COVID-19 vaccine for adolescents aged 12-15 years on May 10, 2021, COVID-19 vaccination is now available to all adolescents aged 12-17 years. Moderna has also applied for emergency use authorization approval for this age group.1 The Centers for Disease Control and Prevention strongly recommends vaccination of the adolescent population, which comprises approximately 25 million people in the United States. Comprehensive protection is critical to adolescent and population health and is a big step toward a return to “normal life” for young people, including in-person school. Vaccine hesitancy—the reluctance or refusal to choose vaccination—identified by the World Health Organization as a top 10 global health threat, undermines these goals. According to a June 2021 Kaiser Family Foundation COVID-19 poll, 42% of parents with adolescents aged 12-17 years said they had either already vaccinated their children or planned to vaccinate their children, 18% said they would “wait a while to see how it is working,” 25% were definitely opposed, and 10% would choose vaccination only if required for school.

Published: August 2021   Journal: Risk Management and Healthcare Policy
Of 628 women, 11.8% (n = 74) were pregnant at the time of survey. Most of the pregnant women (89.2%, n = 66) had some degree of concerns about their unborn babies getting infected during delivery in the hospital. Among mothers of children under 10 years of age (n = 564), half (n = 282) reported change in their children’s behavior during the lockdown. Most mothers and pregnant women (94.9%, n = 569) had some degree of psychological distress. Mothers and pregnant women with a college degree had significantly lower psychological distress (β = -1.346; p = 0.014) than women with a high school education or less. Similarly, mothers and pregnant women with monthly family income ≥ US$ 1,333 had lower psychological distress than those with < US$ 1,333. Women with pre-existing chronic physical (β = 2.424; p < 0.001) or mental (β = 4.733; p < 0.001) conditions had higher psychological distress than those without these conditions. Having children in the house was a contributory factor for higher psychological distress. For example, mothers with one child (β = 2.602; p = 0.007) had significantly higher psychological distress compared to expectant mothers without children in the house.

The impact of Coronavirus disease 2019 (COVID-19) on children aged 3–6 can be severe. Vaccination for COVID-19 is one of the most important primary preventative measures to reduce disease transmission. Parents are hesitant to vaccinate their children against COVID-19 because it was reported in the news that some adults have had adverse reactions to the vaccine. This study aims to investigate the willingness of Chinese parents of 3–6 year old children to vaccinate them with the COVID-19 vaccine and identify what factors influence their decisions. A survey was conducted using a two-stage stratified random sampling method from December 2020 to February 2021. We used univariate analysis and multivariate binary logistic analysis to explore potential factors that may determine the acceptance of the COVID-19 vaccine.
Repurposing of the childhood vaccines: could we train the immune system against the SARS-CoV-2

Published: August 2021   Journal: Expert Review of Vaccines

The COVID-19 pandemic is a globalized health concern caused by a beta-coronavirus named Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Since December 2019, when this outbreak flared in Wuhan, China, COVID-19 cases have been continuously rising all over the world. Due to the emergence of SARS-CoV-2 mutants, subsequent waves are flowing in a faster manner as compared to the primary wave, which is more contagious and causing higher mortality. Recently, India has emerged as the new epicenter of the second wave by mutants of SARS-CoV-2. After almost eighteen months of this outbreak, some COVID-19 dedicated therapeutics and vaccines are available, and a few are under trial, but the situation is still uncontrolled. This perspective article covers the repurposing of childhood vaccines like Bacille Calmette–Guerin (BCG), Measles, Mumps, Rubella (MMR), and Oral Polio Vaccine (OPV), which are live attenuated vaccines and have been shown the protective effect through ‘trained immunity and ‘crossreactivity.'

Published: August 2021   Journal: Journal of Korean Medical Science

Coronavirus disease 2019 (COVID-19) vaccination is necessary to reach herd immunity and essential for mitigating the spread of the pandemic. In May 2021, the US FDA and the EU have expanded the emergency use authorization for a COVID-19 vaccine to children aged 12 to 15. The aim of this study was to investigate parental acceptability of COVID-19 vaccination for their children, factors affecting their acceptability, and children's perceptions of COVID-19 vaccines in Republic of Korea. A questionnaire survey at two tertiary hospitals was conducted from May 25, 2021 to June 3, 2021. Subjects were parents having children under 18 years and children aged 10–18 years.

SARS-CoV-2 infection risk during delivery of childhood vaccination campaigns: a modelling study

Published: August 2021   Journal: BMC Medicine

The COVID-19 pandemic has disrupted the delivery of immunisation services globally. Many countries have postponed vaccination campaigns out of concern about infection risks to the staff delivering vaccination, the children being vaccinated, and their families. The World Health Organization recommends considering both the benefit of preventive campaigns and the risk of SARS-CoV-2 transmission when making decisions about campaigns during COVID-19 outbreaks, but there has been little quantification of the risks. This study modelled excess SARS-CoV-2 infection risk to vaccinators, vaccinees, and their caregivers resulting from vaccination campaigns delivered during a COVID-19 epidemic. It used population age structure and contact patterns from three exemplar countries (Burkina Faso, Ethiopia, and Brazil). It combined an existing compartmental transmission model of an underlying COVID-19 epidemic with a Reed-Frost model of SARS-CoV-2 infection risk to vaccinators and vaccinees. It explored how excess risk depends on key parameters governing SARS-CoV-2 transmissibility, and aspects of campaign delivery such as campaign duration, number of vaccinations, and effectiveness of personal protective equipment (PPE) and symptomatic screening.

Published: July 2021   Journal: Reproductive Health
This study provides a situational update on COVID-19 in Ghana, the seventh African country reporting the most cases. Some modifications occurring within the health system to curtail the outbreak and its potential impact on the delivery of antenatal care services are also highlighted. With the discovery of the Delta variant in Ghana, the current attention is to prevent a third wave of infection, and also control and manage existing cases. Efforts to procure vaccines, vaccinate special populations and sensitize the public on the implications of vaccine hesitancy are ongoing.

Published: July 2021   Journal: Vaccine
Once COVID-19 vaccines are approved for children < 12 years of age, high pediatric vaccination coverage will be needed to help minimize the public health threat from the SARS-CoV-2 epidemic. We conducted an online survey of 1,119 parents and caregivers of children ≤ 12 years in New York City from March 9 to April 11, 2021. Among parents surveyed, 61.9% reported plans to vaccinate their youngest child for COVID-19, 14.8% said they do not plan to vaccinate their child and 23.3% were unsure. Female and non-Hispanic Black parents were least likely to report plans to vaccinate their children. Safety, effectiveness and perceptions that children do not need vaccination were the primary reasons for vaccine hesitancy/resistance. Parents who have or will vaccinate themselves were significantly more likely to report they would vaccinate their children.

Published: July 2021   Journal: Journal of Community Health
Childhood vaccine hesitancy has been studied extensively before the COVID-19 pandemic. The pandemic presented new barriers to pediatric vaccinations. Furthermore, the development of COVID-19 vaccines has complicated factors underlying vaccine hesitancy. This study performed a cross-sectional mobile phone-based survey at Children’s Hospital Los Angeles querying parents regarding perspectives on vaccines before and during the pandemic. Its primary aim was to understand the impact of the pandemic on routine childhood vaccine hesitancy. Secondarily, it examined intent to vaccinate, COVID-19 vaccine hesitancy, and key contributing demographic factors.
