The COVID-19 pandemic has spotlighted the potential of in vitro transcribed (IVT) mRNA vaccines with their demonstrated efficacy, safety, cost-effectiveness, and rapid manufacturing. Numerous IVT mRNA vaccines are now under clinical trials for a range of targets, including infectious diseases, cancers, and genetic disorders. Despite their promise, IVT mRNA vaccines face hurdles such as limited expression levels, nonspecific targeting beyond the liver, rapid degradation, and unintended immune activation.

The coronavirus disease 2019 (COVID-19) pandemic poses a disruptive impact on public health and the global economy. Fortunately, the development of COVID-19 vaccines based on in vitro-transcribed messenger RNA (IVT mRNA) has been a breakthrough in medical history, benefiting billions of people with its high effectiveness, safety profile, and ease of large-scale production. This success is the result of decades of continuous RNA research, which has led to significant improvements in the stability and expression level of IVT mRNA through various approaches such as sequence optimization and improved preparation processes.

Article Synopsis
  • - The SARS-CoV-2 pandemic highlights the ongoing risks of mucosal infectious diseases, with a focus on developing effective mucosal immunity through innovative vaccine methods.
  • - Researchers created self-assembling peptide-poloxamine nanoparticles for administering a COVID-19 DNA vaccine that enhance gene delivery and ensure strong immune responses, including significant production of mucosal IgA and memory T-cells.
  • - Their study found that this vaccine method completely prevents SARS-CoV-2 infection in mice and achieves a 100% survival rate after exposure, showing promise for broader immune protection against the virus.

In vitro transcribed messenger RNA (mRNA) vaccines have displayed enormous potential in fighting against the coronavirus disease 2019 (COVID-19) pandemic. Efficient and safe delivery systems must be included in the mRNA vaccines due to the fragile properties of mRNA. A self-assembled peptide-poloxamine nanoparticle (PP-sNp) gene delivery system is specifically designed for the pulmonary delivery of nucleic acids and displays promising capabilities in mediating successful mRNA transfection.

This current consensus paper for long COVID complements the existing AWMF S1 guidelines for long COVID with a detailed overview on the various clinical aspects of long COVID in children and adolescents. Members of 19 different pediatric societies of the DGKJ convent and collaborating societies together provide expert-based recommendations for the clinical management of long COVID based on the currently available but limited academic evidence for long COVID in children and adolescents. It contains screening questions for long COVID and suggestions for a structured, standardized pediatric medical history and diagnostic evaluation for patients with suspected long COVID.
