Summary: This study investigates the relationship between immune cell responses after BCG vaccination and Mycobacterium tuberculosis (Mtb) infection in HIV-exposed but uninfected infants, as well as their impact on tuberculin skin test (TST) induration. The results show that a monofunctional TNF+ CD4+ effector memory T-cell response at 6-10 weeks of age is associated with Mtb infection at 14 months, while mycobacterial antigen-specific polyfunctional effector memory Th1 responses at 6-10 weeks correlate positively with TST induration in infants without evidence of Mtb infection, which is attenuated by INH therapy.

Summary: In this study, chimeric HPV:HIV VLPs were constructed by inserting HIV-1 P18I10 CTL peptide and T20 anti-fusion peptide into the HPV16 L1 capsid protein. The insertion did not affect the stability, self-assembly, morphology, and antibody reactivity of the VLPs. The chimeric VLPs induced both HPV16- and HIV-1-specific immune responses, making them a potential vaccine platform for controlling HPV16 and HIV-1 infection.

Summary: The study demonstrates that using cold water in heat-exposed laying hens can maintain productivity and immune function under high ambient temperature. The feed intake and egg production were improved by using cold water. Additionally, the cold water restored the immune parameters in the blood, including B-cell, helper T cells, and the ratio of helper/cytotoxic T cells, as well as certain cytokines and immunoglobulin G. This suggests that cold water is a beneficial mechanism to consider for heat stress in laying hens.

Summary: In sub-Saharan Africa, most infants acquire Cytomegalovirus (CMV) infection within the first year of life. Maternal long-term antiretroviral therapy (ART) has been suggested to reduce CMV acquisition in HIV-exposed infants. However, this study found no difference in the prevalence of CMV viremia between HIV-exposed and -unexposed infants at 6 months of age, indicating that long-term ART may not be effective in reducing CMV infection.

Summary: The study reveals significant heterogeneity in antibody responses following SARS-CoV-2 infection, with limited decay of antibody titers over time. Observing neutralization, Fc-function, and SARS-CoV-2 specific T cell responses requires reaching a certain threshold of receptor-binding domain (RBD)-specific antibody titers, indicating a switch-like relationship between antibody titer and function.

Summary: The uptake of pertussis and influenza vaccines in pregnant women was evaluated in a midwife-led immunisation clinic in the UK. The study found that the vaccine uptake was higher than the national or regional average. Factors influencing the decision to accept vaccination included healthcare professional recommendation, perceived susceptibility and risk of infection, and previous experience with vaccination and vaccine-preventable disease. The model of vaccine delivery was associated with high levels of satisfaction and could be implemented elsewhere to increase vaccine uptake, including for COVID-19 vaccines in the future.

Summary: Congenital human cytomegalovirus (CMV) infection is a common condition with long-term consequences for children. However, it is not well-known among pregnant women, families, and healthcare providers. Timely diagnosis and treatment are important for reducing transmission and improving outcomes for infants. Further research is needed to inform screening, outcomes, and treatment decisions.

Summary: Vaccination during pregnancy can protect women and infants from invasive Group B Streptococcus (GBS) disease. A study in England showed that neonatal dried blood spots (DBS) can be used to determine the amount of maternally derived antibody protecting infants from GBS disease. However, due to suboptimal storage conditions, no difference in GBS IgG levels was found between DBS samples from cases and controls.

Summary: In 2014, the Global Alignment on Immunization safety Assessment in pregnancy consortium (GAIA) was established to monitor the safety of vaccines in pregnancy. This review identified and described studies evaluating the performance of 26 standardized definitions for adverse events. Four studies evaluating 13 GAIA case definitions were found, with most assessments done in high-income settings. Recommendations were made to improve the definitions' performance, including ensuring consistency and clarity. Future research should focus on evaluating the remaining case definitions in low- and middle-income settings.
