Summary: This study assessed the cost-effectiveness of pediatric influenza vaccination with the intranasal live-attenuated influenza vaccine (LAIV). It found that the implementation of LAIV vaccination in the pediatric population is cost-effective when compared to other strategies. Factors such as the efficacy of LAIV for children, vaccination coverage, vaccine prices, and herd immunity were significant contributors to the cost-effectiveness.

Summary: This study conducted a systematic review and meta-analysis on the efficacy and safety of spray live attenuated influenza vaccine (LAIV), finding that LAIV was associated with a higher probability of seroconversion for the A/H1N1 serotype, and had no significant association with systemic adverse events, with only rhinorrhea, nasal congestion, and sore throat being significantly associated with LAIV compared to the placebo.

Summary: Influenza A viruses (IAV) are highly contagious and have a significant impact on human and animal health as well as the global economy. The NS1 protein of IAV plays a crucial role in counteracting the host's immune responses during infection. Recent advances in reverse genetics have allowed researchers to modify the viral genome to create recombinant IAV, providing a platform for developing effective vaccine strategies. Truncation or deletion of the NS1 protein has resulted in attenuated viruses that induce strong immune responses and provide high levels of protection against wild-type IAV.

Summary: PRRSV, a widely prevalent RNA virus in pigs, causes significant economic losses globally. Vaccines, including modified live and inactivated vaccines, are currently the best countermeasures against PRRSV infection, but are still facing challenges due to the virus's variability and interaction complexity with host immune responses. Novel strategies are being explored to develop more effective vaccines against this evolving virus.

Summary: The H9N2 avian influenza virus is a significant zoonotic pathogen and can easily recombine with other subtypes to generate novel viruses. In this study, a new H9N2 live attenuated strain was developed to intercept reassortments and showed good genetic stability and immunogenicity in chickens.

Summary: Live-attenuated Rift Valley fever (RVF) vaccines replicate temporarily in the host, stimulating an innate and adaptive immune response. Neutralizing antibodies specific to the RVF virus (RVFV) are crucial for protection. Traditional live-attenuated RVF vaccines have been associated with adverse effects in gestating livestock. However, novel live-attenuated RVF vaccines with improved safety profiles are being developed and evaluated for use in animals and humans. These next-generation vaccines offer opportunities to improve global health.

Summary: Live attenuated influenza vaccines with truncated NS1 have broad protective efficacies through elevated interferon responses. Screening viral subpopulations with enhanced interferon-inducing capacities can guide the design of more effective live vaccines.

Summary: Research has shown that the measles, mumps, and rubella (MMR) vaccine exhibits anti-tumor activity. Intratumoral delivery of low doses of MMR increases infiltration of CD8+ T-cells and decreases macrophages, leading to tumor control and improved survival. Additionally, the vaccine activates the host's antitumor immunity, resulting in coordinated cancer cell death.

Summary: The study shows that pre-treatment with Delta NS1 virus creates an antiviral state, preventing replication of homologous and heterologous viruses, thus preventing diseases caused by virus respiratory pathogens, including SARS-CoV-2. This suggests that Delta NS1 influenza viruses could be used for prophylaxis against influenza, SARS-CoV-2, and other human respiratory viral infections, and that a vaccine based on Delta NS1 live attenuated viruses would provide broad protection against influenza virus infection.

Summary: The study demonstrates that a Newcastle disease virus-based vectored-vaccine shows strong immunogenicity, safety, and protective efficacy in mice and hamsters. Animals vaccinated with this vaccine exhibit significantly decreased infection and pathological lesions following SARS-CoV-2 challenge, as well as reduced shedding of the virus.

Summary: Summary: This study found that nasal pneumococcal colonization had no impact on antibody response to influenza induced by tetravalent-inactivated influenza vaccine (TIV), but it dampened mucosal antibody response to live attenuated influenza vaccine (LAIV), affecting the efficacy of LAIV. Additionally, the LAIV group showed more apparent pulmonary influenza-specific cellular responses compared to the unvaccinated and TIV groups.

Summary: Current seasonal influenza vaccines have suboptimal effectiveness, especially in seasons dominated by viruses that do not match the vaccine. Finding new approaches to improve the immunogenicity and efficacy of traditional influenza vaccines is of high priority for public health. In this study, the researchers tested the hypothesis that truncation of the nonstructural protein 1 (NS1) and the replacement of the nucleoprotein (NP) of the A/Leningrad/17 master donor virus with a recent NP, i.e., switching to 5:3 genome composition, could improve the cross-protective potential of the LAIV virus.

Summary: This study found that among children with asthma aged 5 to 17 years, LAIV4 was not associated with an increased frequency of asthma exacerbations or asthma-related symptoms compared to IIV4. There were no significant differences in asthma symptoms or lung function changes within 14 days post-vaccination between the two groups.

Summary: This study aimed to estimate the utilization of PIM and incidence of ADE in older adults with CKD. The research found that despite the high utilization of PIM, only a small number of these drugs eventually led to hospitalization due to ADE, suggesting an assessment of potential ADE severity to a PIM list is prudent.

Summary: The study investigated the impact of heart geometry and metabolic activity variations over the cardiac cycle on P-31 MRS data quality and metabolite ratios. By triggering acquisitions to end-systole, improved signal amplitudes and fit quality were observed. The study concluded that triggering to end-systole is superior to triggering to diastasis.

Summary: Individuals with previous SARS-CoV-2 infection showed significantly higher antibody response after receiving the first dose of the Pfizer vaccine compared to those who were naive to the virus. This suggests the need for further research on whether individuals with prior infection would benefit from a two-dose vaccination schedule or if the second doses could be saved for others in need.
