Advances in molecular biology and immunology in the past 10-15 years have allowed for a greater understanding of the molecules present on melanoma cells that are recognised by the immune system. The rising incidence of melanoma, combined with lack of efficacy of cytotoxic therapies, means there is a significant need for the development of effective immunotherapies. We discuss three types of vaccine for melanoma, which are currently in phase III clinical trials: allogeneic and autologous cellular vaccines, and carbohydrate vaccines. We also discuss several new areas of vaccine development, including DNA vaccines, dendritic-cell-based vaccines, peptide vaccines, and heat-shock protein vaccines. Although initial clinical trials have shown the safety and immunological efficacy of vaccines for melanoma, the true clinical benefit of these strategies will only be revealed in large randomised trials.

Introduction: Coronavirus disease 2019 (COVID-19) is a life-threatening disease that was declared a pandemic in March 2020. Organ transplant recipients are vulnerable to infection and complications from COVID-19. The objective of this study was to investigate the rates of infection, mortality, and case-fatality ratios (CFR) in solid organ transplant recipients and patients on the waiting list for organ allocation in the period prior to the availability of specific vaccines.

Introduction: Despite efforts by health organizations to share evidence-based information, fake news hindered the promotion of social distancing and vaccination during the coronavirus disease 2019 (COVID-19) pandemic. This study analyzed COVID-19 knowledge and practices in a vulnerable area in northern Rio de Janeiro, acknowledging the influence of the complex social and economic landscape on public health perceptions.
Methodology: This cross-sectional study was conducted in Novo Eldorado - a low-income, conflict-affected neighborhood in Campos dos Goytacazes - using a structured questionnaire, following the peak of COVID-19 deaths in Brazil (July-December 2021).
Introduction: China implemented a dynamic zero-COVID strategy to curb viral transmission in response to the coronavirus disease 2019 (COVID-19) pandemic. This strategy was designed to inhibit mutation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus responsible for COVID-19. This study explores the dynamics of viral evolution under stringent non-pharmaceutical interventions (NPIs) through real-world observations.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).
