Narrative review of the clinical safety of MenACYW-TT: a quadrivalent meningococcal vaccine conjugated to tetanus toxoid licensed in the US and abroad.

Syrkina Olga O, Bausch-Jurken Mary M, Delgado Arlette A, Jovanovic Jelena J et al.

Routine meningococcal vaccination campaigns have substantially reduced the burden of invasive meningococcal disease in pediatric individuals, leading to relative increases in burden in older age groups. There is a need for safe, effective meningococcal vaccines that can be used across broad age ranges. MenACYW-TT, a quadrivalent tetanus-toxoid-conjugate meningococcal vaccine indicated for individuals aged ≥6 weeks, is one such option. This narrative review summarizes safety data from industry-sponsored pre- and post-licensure clinical trials of MenACYW-TT, including head-to-head studies with active comparators and coadministration studies with routine pediatric vaccines. In >30 trials involving >17,000 participants, MenACYW-TT had a consistent safety profile across all age groups, from infants to older adults. The most frequent side effects were generally mild or moderate and transient; vaccine-related serious adverse events were rare (<0.1%). The safety of MenACYW-TT was comparable to that of other quadrivalent meningococcal conjugate vaccines. Coadministration did not materially affect the safety of MenACYW-TT or routine pediatric vaccines. Immunization remains an essential preventive strategy against the potentially life-threatening and life-altering consequences of invasive meningococcal disease. The favorable benefit-risk profile of MenACYW-TT reinforces the safety of licensed vaccines and can help to counter vaccine hesitancy.

COVID-19 Vaccine Knowledge, Practice, and Attitudes Among Hemodialysis Patients in Egypt, Kenya, and Cameroon: A Multicenter Study.

Elsayed Enass E, Kotb Khaled M KM, Heiba Ahmed A, Elhussini Manal Shaker MS et al.

Patients receiving hemodialysis (HD) are at increased risk of severe coronavirus disease 2019 (COVID-19) and were prioritized for vaccination, yet vaccine hesitancy remains common. We assessed COVID-19 vaccine knowledge, acceptance, and attitudes among patients receiving HD in Egypt, Kenya, and Cameroon and identified factors associated with vaccine acceptance, prior infection, willingness to receive future doses, and postvaccination complications. Multicenter cross-sectional survey study. Between March 2021 and April 2022, 765 patients receiving maintenance HD and 196 non-dialysis controls were recruited from dialysis centers in Egypt, Kenya, and Cameroon. Sociodemographic characteristics, clinical comorbidities, prior COVID-19, sources of vaccine information, and exposure to vaccinated or infected relatives. COVID-19 vaccine acceptance, willingness to receive future doses, prior infection, and post-vaccination complications. Structured questionnaires assessed knowledge, practices, and attitudes toward COVID-19 vaccination. Multivariable logistic regression identified factors independently associated with study outcomes. Vaccine acceptance was lower among patients receiving HD than nondialysis controls (58.2% vs 96.2%). Fear of side effects was the most common reason for refusal (39.3%). Postvaccination complications were less frequent among patients receiving HD (22.3% vs 44.3%). Hesitancy was more common among women, younger participants, and those with comorbidities or no prior COVID-19. Having vaccinated or previously infected relatives was associated with a greater willingness to receive future doses. Cross-sectional design limits causal inference. Nonprobability sampling and unmatched controls may limit generalizability. COVID-19 cases may have been underreported because of limited testing. COVID-19 vaccine hesitancy among patients receiving HD is driven by fear, misinformation, and sociodemographic factors. Targeted education and improved access to reliable vaccine information may help increase uptake in this population.

A cavity-reduced prefusion RSV F bivalent vaccine elicits durable and protective immunity.

Liu Lijie L, Yan Mengrong M, Liang Ruoxu R, Wu Qingxin Q et al.

Respiratory syncytial virus (RSV) remains a major cause of severe respiratory disease, and stabilization of the prefusion (preF) conformation of the F glycoprotein is central for vaccine development. Here, we report a structure-guided engineering strategy that enhances preF stability by reducing the hydrophobic cavity within the trimeric F protein. Targeted modifications at metastability-associated sites generated RVF-88, a disulfide-free stabilized preF immunogen that preserves key neutralizing epitopes, including antigenic site Ø, while exhibiting improved structural integrity and long-term storage stability. Formulated as an unadjuvanted bivalent vaccine, RVF-88 elicited potent neutralizing antibody responses and durable immune protection lasting up to 5 months in mice. Vaccination also protected both mice and cotton rats against RSV challenge. Structural analyses confirmed the intended cavity-reduction design, revealing a reduced apical hydrophobic cavity volume and surface area while maintaining the prefusion architecture. Together, these findings establish hydrophobic cavity reduction as a rational strategy for stabilizing prefusion RSV F and provide a promising next-generation vaccine candidate with improved stability and immunogenicity for further clinical development.

Immunogenicity and Safety of the 9-valent Human Papillomavirus (HPV) Vaccine Administered as 2-Dose or 3-Dose Regimens in Japanese Boys and Girls Aged 9-15 Years.

Takeuchi Yuzuru Y, Yonekawa Motoharu M, Murata Shinya S, Nakagomi Mariko M et al.

A phase III open-label study evaluated the immunogenicity and safety of the 9-valent human papillomavirus (9vHPV) vaccine in Japanese boys and girls. Japanese boys aged 9-15 years (n = 105) received a 3-dose (Day 1, Month 2, and Month 6) regimen; Japanese boys (n = 104) and girls aged 9-14 years (n = 105) received a 2-dose (Day 1 and Month 6) regimen. Antibody responses to HPV6/11/16/18/31/33/45/52/58 were assessed at Month 7, 18, and 30 using a competitive Luminex immunoassay. Injection-site adverse events (AEs; Days 1 to 5 post-dose), systemic AEs (Days 1 to 15 post-dose), and serious AEs (duration of study) were assessed. At Month 7, for HPV types targeted by the 9vHPV vaccine, seroconversion rates were 100% in all three arms, and in cross-study comparisons with efficacy studies, anti-HPV geometric mean titers in boys were noninferior to those in Japanese men aged 16-26 years, and in girls were noninferior to those in Japanese women aged 16-26 years. Most injection-site AEs were mild to moderate in intensity. No deaths or vaccine-related serious AEs were observed. These results support immunobridging of efficacy findings in Japanese men and women to Japanese boys and girls. The 9vHPV vaccine was generally well tolerated.

Rare Presentation of Parsonage-Turner Syndrome Post Tdap Vaccination: A Case Report.

Jervis Matthew M, Dunn-Pirio Anastasie A

Parsonage-Turner Syndrome (PTS) is a rare disorder of the brachial plexus typically characterized by acute shoulder and/or upper extremity pain, followed by muscle weakness. Though the specific etiology of PTS is unclear, numerous associations are cited in the literature, including after routine vaccinations. A previously healthy 22-year-old male developed subacute left upper extremity weakness and numbness < 24 hours following a routine Tdap (tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis) booster vaccination, later evolving into diffuse weakness and sharp shoulder pain. Electromyography (EMG) findings were suggestive of early PTS, and subsequent magnetic resonance imaging (MRI) of the brachial plexus confirmed mild inflammatory changes consistent with brachial plexitis. Over several months, the patient showed clinical improvement with conservative management. This case highlights a rare presentation of post-vaccination PTS, emphasizing the need for early recognition and supportive management. Although rare, clinicians should consider PTS in patients presenting with acute-onset upper extremity pain and weakness following vaccination.
