COVID-19 vaccination in children and adolescents aged 5 years and older undergoing treatment for cancer and non-malignant haematological conditions: Australian and New Zealand Children's Haematology/Oncology Group consensus statement.

INTRODUCTION: The Australian Technical Advisory Group on Immunisation and New Zealand Ministry of Health recommend all children aged ≥ 5 years receive either of the two mRNA COVID-19 vaccines: Comirnaty (Pfizer), available in both Australia and New Zealand, or Spikevax (Moderna), available in Australia only. Both vaccines are efficacious and safe in the general population, including children. Children and adolescents undergoing treatment for cancer and immunosuppressive therapy for non-malignant haematological conditions are particularly vulnerable, with an increased risk of severe or fatal COVID-19. There remains a paucity of data regarding the immune response to COVID-19 vaccines in immunosuppressed paediatric populations, with data suggestive of reduced immunogenicity of the vaccine in immunocompromised adults. RECOMMENDATIONS: Considering the safety profile of mRNA COVID-19 vaccines and the increased risk of severe COVID-19 in immunocompromised children and adolescents, COVID-19 vaccination is strongly recommended for this at-risk population. We provide a number of recommendations regarding COVID-19 vaccination in this population where immunosuppressive, chemotherapeutic and/or targeted biological agents are used. These include the timing of vaccination in patients undergoing active treatment, management of specific situations where vaccination is contraindicated or recommended under special precautions, and additional vaccination recommendations for severely immunocompromised patients. Finally, we stress the importance of upcoming clinical trials to identify the safest and most efficacious vaccination regimen for this population. CHANGES IN MANAGEMENT AS A RESULT OF THIS STATEMENT: This consensus statement provides recommendations for COVID-19 vaccination in children and adolescents aged ≥ 5 years with cancer and immunocompromising non-malignant haematological conditions, based on evidence, national and international guidelines and expert opinion. ENDORSED BY: The Australian and New Zealand Children's Haematology/Oncology Group.

Parents' Experiences of Childhood Cancer During the COVID-19 Pandemic: An Australian Perspective.

INTRODUCTION: COVID-19 has had far-reaching impacts including changes in work, travel, social structures, education, and healthcare. OBJECTIVE: This study aimed to explore the experiences of parents of children receiving treatment for cancer during the COVID-19 pandemic. METHODS: Parents whose children were currently in treatment for childhood cancer or had completed treatment in the previous 12 months, participated in semi-structured interviews, face-to-face or via teleconferencing. Thematic analysis was used to analyze the data. RESULTS: The sample consisted of 34 participants (17 fathers and 17 mothers) from all states across Australia. Median age 37.5 years (range 29-51, years, SD = 6.3). Five main themes were identified: "Welcome to the Club"; "Remote Work and Study"; "Silver Linings"; "The Loneliest Experience" with three sub-themes "Immediate Family"; "Friends"; and "Overseas Family" and "Lack of Support" with two sub-themes: "Community Support" and "Organized Support." CONCLUSION: These findings revealed contrasting experiences of the impact of the COVID-19 pandemic. For parents whose children were neutropenic, the pandemic provided benefits in increased community understanding of infection control. Parents also reflected that the movement to remote work made it easier to earn an income. In contrast, some parents observed that restrictions on visitors and family intensified feelings of isolation. Parents also described how the COVID-19 reduced access to support services. These findings contribute to an understanding of the multifaceted impacts of the COVID-19 pandemic on families of children with cancer.
