Pneumococcal infections are a serious health issue associated with increased morbidity and mortality. This systematic review evaluated the efficacy, effectiveness, immunogenicity, and safety of the pneumococcal conjugate vaccine (PCV)15 compared to other pneumococcal vaccines or no vaccination in children and adults. We identified 20 randomized controlled trials (RCTs). A meta-analysis of six RCTs in infants showed that PCV15 was non-inferior compared with PCV13 for 12 shared serotypes. Based on a meta-analysis of seven RCTs in adults, PCV15 was non-inferior to PCV13 for 13 shared serotypes. For the unique PCV15 serotypes, 22F and 33F, immune responses were higher in infants and adults vaccinated with PCV15 compared to those receiving PCV13. Regarding safety, meta-analyses indicated comparable risks of adverse events between PCV15 and PCV13 in infants. Adults receiving PCV15 had a slightly higher risk of adverse events, though serious events were similar between groups.

Background: Due to its strong immunogenicity and tumor specificity, neoplastic antigen has emerged as an immunotherapy target with wide therapeutic prospect and clinical application value. Anti-programmed death-1 (PD-1) antibodies reinvigorate T cell-mediated antitumor immunity. So, we conducted single-arm trial to assess the safety and efficacy of PD-1 blockade(Camrelizumab)-activated neoantigen specific cellular therapy (aNASCT) on advanced relapsed non-small lung cancer(NSCLC)(ClinicalTrials.

Background: Clostridium butyricum is a probiotic widely used in animal husbandry, and there is evidence to suggest that it can alleviate intestinal inflammation in pigs and may be related to its lipoteichoic acid (LTA), but the mechanism is still unclear.
Objective: This study aimed to determine the regulatory effect and potential mechanism of C. butyricum LTA on LPS-stimulated inflammation in intestinal porcine epithelial line-J2 (IPEC-J2).
Comparative immunogenicity assessment of biosimilar natalizumab to its reference medicine: a matching immunogenicity profile.
Front Immunol
January 2025
Polpharma Biologics S.A., Gdansk, Poland.
Background: Biosimilar natalizumab (biosim-NTZ) is the first biosimilar monoclonal antibody of reference natalizumab (ref-NTZ) for treatment of relapsing forms of multiple sclerosis (MS). Within the totality of evidence for demonstration of biosimilarity, immunogenicity assessments were performed in healthy subjects and patients with relapsing-remitting MS (RRMS) to confirm a matching immunogenicity profile between biosim-NTZ and ref-NTZ.
Methods: Immunogenicity of biosim-NTZ versus ref-NTZ was evaluated in two pivotal clinical studies.

Background: Yttrium-90 FF-21101 (Y-FF-21101) is a radiopharmaceutical that targets P-cadherin as a therapy against solid tumors. A previously reported, first-in-human study determined that a dose of 25 mCi/m was safe, and a patient with clear cell carcinoma of the ovary achieved a complete response. In this article, the authors report the results of Y-FF-21101 treatment in an ovarian carcinoma expansion cohort and in patients with selected solid tumors who had known high P-cadherin expression.
