Streptococcus pneumoniae as a colonizing agent of the Nasopharynx - Oropharynx in adults: A systematic review and meta-analysis
CONCLUSIONS: This study found a low prevalence of Spn NOC in adults. Notably, the prevalence of Spn NOC was higher in younger adults than in older adults. It is essential to highlight a significant heterogeneity among studies, which indicates there is no standardized method of Spn NOC identification.PMID:38514352 | DOI:10.1016/j.vaccine.2024.03.041 (Source: Vaccine)

Yellow fever neutralizing antibody seroprevalence proportion and titers in previously vaccinated adults with chronic kidney disease
Vaccine. 2024 Mar 20:S0264-410X(24)00316-5. doi: 10.1016/j.vaccine.2024.03.029. Online ahead of print.ABSTRACTStudies on yellow fever vaccine (YF) in chronic kidney disease (CKD) patients are scarce. This cross-sectional study aimed to evaluate YF neutralizing antibody seroprevalence and titers in previously vaccinated adults with CKD, on dialysis (D-CKD) or not (ND-CKD), compared to healthy persons. The micro Plaque Reduction Neutralization-Horseradish Peroxidase (μPRN-HP) test was used. Antibody titers were expressed as the reciprocal of the highest dilution that neutralized the challenge virus by 50 % (μPRN50). Seropo...

The influence of health service interactions and local policies on vaccination decision-making in immigrant women: A multi-site Canadian qualitative study
CONCLUSION: Given our participants' different communication preferences and needs, we argue that a one-size-fits-all communication approach is inappropriate for immigrant and refugee populations. Instead, multi-pronged communication strategies are required to reach participants and respond to previous experiences and information that may lead to vaccination hesitancy.PMID:38514354 | DOI:10.1016/j.vaccine.2024.03.014 (Source: Vaccine)

Differences in social media use by COVID-19 vaccination status
Vaccine. 2024 Mar 20:S0264-410X(24)00318-9. doi: 10.1016/j.vaccine.2024.03.031. Online ahead of print.ABSTRACTThe near-ubiquitous use of social media in the United States (U.S.) highlights the utility of social media for encouraging vaccination. Vaccination campaigns have used social media to reach audiences, yet research linking the use of specific social media platforms and vaccination uptake is nascent. This descriptive study assesses differences in social media use by COVID-19 vaccination status among adults overall and those who reported baseline vaccine hesitancy. We used data from a nationally representative longitu...

Is vaccination against measles, mumps, and rubella associated with reduced rates of antibiotic treatments among children below the age of 2  years? Nationwide register-based study from Denmark, Finland, Norway, and Sweden
CONCLUSIONS: Across the Nordic countries, receipt of MMR vaccine after DTaP3 was associated with an 11% lower rate of antibiotic treatments. The negative control analysis suggests that the findings are affected by residual confounding. Findings suggest that potential non-specific effects of MMR vaccine are of limited clinical and public health importance for the milder infections treated out-of-hospital in the Nordic setting.PMID:38508926 | DOI:10.1016/j.vaccine.2024.03.026 (Source: Vaccine)

Transformative vaccination: A pentavalent shield against COVID-19 and influenza with betulin-based adjuvant for enhanced immunity
Vaccine. 2024 Mar 19:S0264-410X(23)01421-4. doi: 10.1016/j.vaccine.2023.11.057. Online ahead of print.ABSTRACTThe development of an effective combined vaccine represents a crucial strategy for preventing outbreaks of infectious diseases and reducing the burden on healthcare resources. Developing a combined vaccine against both influenza and the coronavirus is a promising approach, but it is still in the early stages of development. This paper reports on a novel combined pentavalent candidate vaccine that has shown promising results in mice, with statistically significant differences in mean antibody titer against the coron...

Online ahead of print.ABSTRACTInvestigating the mechanisms by which W135 meningococcal conjugate (PSW135-TT) activates adaptive immune responses in mice can provide a comprehensive understanding of the immune mechanisms of bacterial polysaccharide conjugate vaccines. We compared B-cell and T-cell immune responses immunized with W135 meningococcal capsular polysaccharides (PSW135), tetanus toxoid (TT) and PSW135-TT in mice. The results showed that PSW135-TT could induce higher PSW135-specific and TT-specific IgG antibodies with a significant enh...

Subolesin knockdown in tick cells provides insights into vaccine protective mechanisms
In this study, transcriptomics and proteomics analyses were conducted together with graph theory data analysis in wild type and Sub knockdown (KD) tick ISE6 cells in order to identify and characterize the functional implications of Sub in tick cells. The results support a key role for Sub in the regulation of gene expression in ticks and the relevance of this antigen in vaccine development against ticks and TBDs. Proteins with differential representation in response to Sub KD provide insights into vaccine protective mechanisms and candidate tick protective antigens.PMID:38508929 | DOI:10.1016/j.vaccine.2024.03.006 (Source: Vaccine)

Online ahead of print.ABSTRACTThe COVID-19 pandemic has highlighted the need for mucosal vaccines as breakthrough infections, short-lived immune responses and emergence of new variants have challenged the efficacy provided by the first generation of vaccines against SARS-CoV-2 viruses. M2SR SARS-CoV-2, an M2-deleted single-replication influenza virus vector modified to encode the SARS-CoV-2 receptor binding domain, was evaluated following intranasal delivery in a hamster challenge model for protection against Wuhan SARS-CoV-2. An adjuvanted ina...

Globally in 2019, an estimated 1.27 million (95% Uncertainty Interval [UI]: 0.91-1.71) and 4.95 million (95% UI: 3.62-6.57) deaths were attributed to and associated with bacterial antimicrobial resistance (AMR), respectively. K. pneumoniae was the second leading pathogen in deaths attributed to AMR resistant bacteria. Furthermore, the rise of antimicrobial resistance in both community- and hospital-acquired infectio...

Comparison of the safety and efficacy of the wild-type and lpxL/lpxM mutant inactivated vaccine against the avian pathogenic Escherichia coli O1, O2, and O78 challenge
In this study, mutant strains of lpxL/lpxM and their O1, O2, and O78 wild-type strains were developed for an inactivated vaccine (referred to as the mutant vaccine and the wild-type vaccine, respectively), and the safety and effectiveness of these two prototype vaccines were assessed in white Leghorn chickens. Findings indicated that chickens immunized with the mutant vaccine showed a return of appetite sooner post-immunization and experienced earlier disappearance of nodules at the injection site compared to those immunized with the wild-type vaccine. Pathological examinations revealed that lesions were still present in t...

CHO cells for virus-like particle and subunit vaccine manufacturing
Vaccine. 2024 Mar 18:S0264-410X(24)00321-9. doi: 10.1016/j.vaccine.2024.03.034. Online ahead of print.ABSTRACTChinese Hamster Ovary (CHO) cells, employed primarily for manufacturing monoclonal antibodies and other recombinant protein (r-protein) therapeutics, are emerging as a promising host for vaccine antigen production. This is exemplified by the recently approved CHO cell-derived subunit vaccines (SUV) against respiratory syncytial virus (RSV) and varicella-zoster virus (VZV), as well as the enveloped virus-like particle (eVLP) vaccine against hepatitis B virus (HBV). Here, we summarize the design, production, and immu...
