Difficult questions about long COVID in children

Maren Johanne Heilskov Rytter

Published: June 2022   Journal: The Lancet Child & Adolescent Health
The COVID-19 pandemic is likely to leave long-lasting marks on a generation of children and young people, mainly from indirect effects, including those of school closures, social isolation and a so-called immunity debt resulting from 2 years with reduced exposure to common pathogens. A small proportion of children have had serious sequelae of SARS-CoV-2 infection itself, with the most dramatic being multisystem inflammatory syndrome in children (MIS-C).  Furthermore, a less well-defined entity, termed long COVID or post-COVID-19 condition, has been suggested, referring to children with long-lasting symptoms after SARS-CoV-2 infection that are not explained by another disease.

Giulia Savarese; Luna Carpinelli; Anna De Chiara (et al.)

Published: June 2022   Journal: Vaccines
The international strategic plan for COVID-19 vaccines remains the practical option for the protection of health. However, vaccine hesitancy remains an obstacle to full population vaccination, with rapid developments in COVID-19 vaccines and concerns about efficacy acting as influencing factors. The present study investigated the perception of vaccine hesitancy among parents of adolescents in order to explore the reasons and related emotional states. In January–March 2022, an online questionnaire was administered to a sample of parents who brought their children to the vaccine center of a local health unit, ASL Salerno (Campania, Italy).

Assessing the prevalence of young children living in households prepared for COVID-19 in 56 low- and middle-income countries

Chunling Lu; Yiqun Luan; Sara N. Naicker (et al.)

Published: June 2022   Journal: Global Health Research and Policy

The COVID-19 pandemic and governments’ attempts to contain it are negatively affecting young children’s health and development in ways we are only beginning to understand and measure. Responses to the pandemic are driven largely by confining children and families to their homes. This study aims to assess the levels of and associated socioeconomic disparities in household preparedness for protecting young children under the age of five from being exposed to communicable diseases, such as COVID-19, in low- and middle-income countries (LMICs). Using data from nationally representative household surveys in 56 LMICs since 2016, we estimated the percentages of young children under the age of five living in households prepared for communicable diseases (e.g., COVID-19) and associated residential and wealth disparities at the country- and aggregate-level. Preparedness was defined on the basis of space for quarantine, adequacy of toilet facilities and hand hygiene, mass media exposure at least once a week, and phone ownership. Disparities within countries were measured as the absolute gap in two domains—household wealth and residential area - and compared across regions and country income groups.

Sandra Lopez-Leon; Talia Wegman-Ostrosky; Norma Cipatli Ayuzo del Valle (et al.)

Published: June 2022   Journal: Scientific Reports
The objective of this systematic review and meta-analyses is to estimate the prevalence of long-COVID in children and adolescents and to present the full spectrum of symptoms present after acute COVID-19. It used PubMed and Embase to identify observational studies published before February 10th, 2022 that included a minimum of 30 patients with ages ranging from 0 to 18 years that met the National Institute for Healthcare Excellence (NICE) definition of long-COVID, which consists of both ongoing (4 to 12 weeks) and post-COVID-19 (≥ 12 weeks) symptoms. Random-effects meta-analyses were performed using the MetaXL software to estimate the pooled prevalence with a 95% confidence interval (CI). Heterogeneity was assessed using I2 statistics.
In whose best interest? Parental hesitancy toward the COVID-19 vaccine for children in Japan: a literature survey study

Shizuko Takahashi; Eisuke Nakazawa; Akira Akabayashi

Published: June 2022   Journal: COVID
In early February 2022, the Japanese government sent COVID-19 vaccine vouchers to children ages 5–11. Using keywords obtained from the voucher, the frequently asked questions section, and experts, this study descriptively analyzed the advantages and disadvantages of vaccination for children and their parents through a web-based literature survey of media articles and government homepage statements in Japan. For children, vaccination helps prevent severe symptoms and may be particularly beneficial for children in low-income families by lowering the rate of suicide and at-home child abuse. For parents, not vaccinating their child allows them to fulfill a more traditional role as a parent (mothers in particular), reduces the gender gap for mothers, and provides greater peace of mind about their child’s future fertility. This study also examined the governmental vaccination campaigns targeting children from public health perspectives.

Mei Zeng; Xiaowen Zhai; Hailing Chang (et al.)

Published: June 2022   Journal: Human Vaccines & Immunotherapeutics
Safety concerns about novel vaccines and necessity of COVID-19 vaccination for children, especially with underlying medical conditions, are the obstacle of COVID-19 vaccination program among pediatric population. The study was conducted to investigate the vaccine hesitancy reasons among the parents, and to monitor the adverse events of inactivated COVID-19 vaccines in children and teenagers with underlying medical conditions in China. Children with underlying medical conditions encountered to the Immunization Advisory Clinic for COVID-19 vaccine counseling were enrolled. They were given immunization recommendation and followed up at 72 h and 28 d after immunization to monitor the immunization compliance after consultation and adverse events. A total of 324 children aged 3–17 y were included. The top three primary medical conditions for counseling were allergy (33.6%), neurological diseases (31.2%) and rheumatic diseases (8.3%). COVID-19 vaccination was promptly recommended for 242 (74.7%) children. Seventy-one (65.7%) children who had allergy issues were recommend to take vaccination, which was significantly lower than that of other medical conditions (p < .05).

Prawira Oka; Benecia Wan Qing Thia; Shyna Zhuoying Gunalan (et al.)

Published: June 2022   Journal: Frontiers in Public Health

COVID-19 vaccination is a key public health measure to mitigate the crippling effects of the pandemic. COVID-19 vaccination began in adults and targeted adolescents at a later stage. However, medical decision-making on its uptake among the latter was unknown, which could be affected by their literacy and concerns about the vaccine. The study aimed to elucidate the awareness, concerns and barriers of adolescents toward the COVID-19 vaccine. A cross-sectional online survey using a self-developed questionnaire was conducted between June to November 2021. The adolescent participants were students from institutes of post-secondary education who were recruited via convenience sampling. The data were collated from an officially approved electronic platform, audited and analyzed. Continuous and categorical variables were expressed as mean (standard deviation) and percentages, respectively.

Martina Capponi; Federica Pulvirenti; Bianca Laura Cinicola (et al.)

Published: June 2022   Journal: Vaccines
Vaccination against COVID-19 is the most effective tool to protect both the individual and the community from this potentially life-threatening infectious disease. Data from phase-3 trials showed that two doses of the BNT162b2 vaccine were safe, immunogenic, and effective against COVID-19 in children aged 5–11 years. However, no surveys in real-life settings have been carried out in this age range. This is a cross-sectional study which aims to evaluate the short-term adverse reactions (ARs) and the rate of protection against infection of the BNT162b2 vaccine in children aged 5–11 years by the compilation of two surveillance questionnaires conceived using Google Forms.
