The rate of invasive pneumococcal disease has markedly declined after the introduction of pneumococcal conjugated vaccines. In spite of the high effectiveness of this vaccine, there are some reports of vaccine failure and vaccine breakthroughs. Data on children with pneumococcal pneumonia in a European tertiary Hospital, from 2012 to 2014, were retrospectively collected before the implementation of pneumococcal conjugated vaccines in our country. We found four cases of pneumococcal serotype 3 vaccine failure and three cases of vaccine breakthroughs (two with serotype 3 and one with serotype 19A). All of these children were previously healthy.

Introduction: Immune-deficient/disordered people (IDP) elicit a less robust immune response to COVID-19 vaccination than the general US population. Despite millions of IDP at presumed elevated risk, few population-level studies of IDP have been conducted in the Omicron era to evaluate breakthrough infection-related outcomes.
Methods: We followed a prospective cohort of 219 IDP and 63 healthy volunteers (HV) in the USA from April 2021 (Alpha variant peak) to July 2023 (Omicron XBB variant peak).

Background: Pediatric patients with autoimmune and inflammatory diseases often require immunosuppressive therapy, which increases their susceptibility to infections, including varicella-zoster virus (VZV). While the live attenuated varicella vaccine is contraindicated in most immunocompromised children, the recombinant subunit vaccine, Shingrix, may offer an alternative preventive strategy. However, data on its safety, immunogenicity, and efficacy in pediatric VZV-naïve patients remain limited.

Understanding factors contributing to anticipatory breadth, wherein affinity maturation against an ancestral strain yields neutralization capacity against evolved variants, is therefore of great importance. Here, we investigated the mechanism of anticipatory breadth development in a public antibody family targeting the functionally restricted ACE2 binding site on SARS-CoV-2.

Non-small cell lung cancer (NSCLC) remains a leading cause of cancer-related mortality worldwide, with only modest improvements in survival despite advances in conventional therapies. Cell-based immunotherapy, which utilizes ex vivo expanded or genetically modified immune cells, has emerged as a promising therapeutic alternative. Approaches such as natural killer (NK) cells, tumor-infiltrating lymphocytes (TILs), dendritic cell (DC)-based vaccines, cytokine-induced killer (CIK) cells, and chimeric antigen receptor T (CAR-T) cells have shown encouraging potential in preclinical and early clinical studies.

Lipid nanoparticles (LNPs) enable RNA delivery, primarily via intramuscular (IM) injection, catalyzing breakthroughs like the Pfizer-BioNTech and Moderna COVID-19 vaccines. LNPs encapsulate RNA, using ionizable lipids for endosomal escape and PEG-lipids for stability. IM administration leverages muscle tissue's immune-rich environment, enabling localized antigen production, reduced systemic toxicity, and scalability.
