Article Abstract
Background: This study evaluated the concurrent use of meningococcal C tetanus conjugate (MenC-TT) vaccine (NeisVac-C) with DTaP-based combinations, according to 2 vaccination schedules, one of which included hepatitis B vaccination at birth (Trial DTaP-HBV-IPV/Hib-097).
Methods: Healthy infants were randomized to receive either DTaP-HBV-IPV/Hib (Infanrix hexa) at 2, 4, and 6 months (N = 115) or HBV at birth followed by DTaP-HBV-IPV/Hib at 2 and 6 months and DTaP-IPV/Hib (Infanrix-IPV Hib) at 4 months (N = 115). In both groups 2 doses of MenC-TT conjugate were coadministered at 2 and 4 months, and compared with 3 doses of MenC-CRM197 conjugate (Meningitec) coadministered at 2, 4, and 6 months with DTaP-HBV-IPV/Hib (N = 120). Antibody concentrations were measured at 2, 6 and 7 months. Solicited local and general symptoms, unsolicited symptoms, and serious adverse events (SAEs) were recorded.
Results: All MenC-TT recipients had seroprotective concentrations of anti-PRP antibodies (> or = 0.15 microg/mL) 1 month after the third vaccine dose and all had SBA-MenC titers > or = 1:8 after the second dose of MenC-TT. These responses were noninferior to those seen after 3 doses of DTaP-HBV-IPV/Hib and MenC-CRM. Anti-PRP antibody GMCs were significantly higher in MenC-TT than MenC-CRM vaccinees (7.9, 7.3, 3.8 microg/mL, respectively). Immune responses to all other coadministered antigens were unimpaired, with seroprotection/seropositivity rates > or = 98.1% in MenC-TT vaccinees. All schedules studied were well tolerated, with no differences in reactogenicity between the study groups.
Conclusions: Coadministration of DTaP-HBV-IPV/Hib or DTaP-IPV/Hib with 2 doses of MenC-TT conjugate vaccine is safe, well tolerated, and immunogenic, with no impairment of the response to the coadministered antigens.

Overview: We analysed Australian Immunisation Register (AIR) data, predominantly for National Immunisation Program funded vaccines, as at 2 April 2023 for children, adolescents and adults, focusing on the calendar year 2022 and on trends from previous years. This report aims to provide comprehensive analysis and interpretation of vaccination coverage data to inform immunisation policy and programs.
Children: Fully vaccinated coverage in Australian children in 2022 was 0.

The rise of antimicrobial resistance (AMR) in , facilitated by mobile genetic elements (MGEs), complicates infection treatment. While pneumococcal conjugate vaccine (PCV) deployment has reduced disease burden, non-vaccine serotypes (NVTs) have increased and now cause invasive disease.

Background: SLE has increased risk of invasive pneumococcal disease due to immune dysregulation and immunosuppression. European Alliance of Associations for Rheumatology recommendations suggest sequential vaccination with conjugate vaccine, followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23). However, data on immunogenicity of sequential vaccination in SLE are limited.

Invasive disease caused by type b (Hib) is a major health concern, particularly in children under 5 years of age and vulnerable populations. Use of Hib conjugate vaccines has significantly reduced the incidence of Hib disease. Among these, the polyribosylribitol phosphate-outer membrane protein complex (PRP-OMPC) conjugate has demonstrated uniquely robust immunogenicity in infants compared to PRP conjugated to tetanus toxoid.

Background: Protein-polysaccharide conjugate vaccines rely on the induction of T-cell-dependent responses that support germinal center (GC) reactions to potentiate the expansion of antigen-specific memory B-cell (MBC) populations and high-avidity antibody responses. The effects of adjuvants on B-cell and antibody responses are well described for protein antigens but remain largely unexplored for conjugated polysaccharidic antigens.
Methods: We assessed the effects of five adjuvants present in licensed vaccines (AS01, AS03, AS04, and aluminum hydroxide [Alum]) or under clinical evaluation (AS37) on the magnitude and quality of antigen-specific antibody responses and local/systemic B-cell responses.
