Article Synopsis
  • Epidemiological studies show that factors like pre-vaccination immune status, age, gender, and vaccination history affect how people respond to influenza vaccines, but results vary across different studies.* -
  • A new Bayesian model was created to analyze the relationships between these host factors and antibody responses after vaccination, revealing that pre-vaccination antibody levels and vaccination history significantly affect post-vaccine antibody dynamics.* -
  • The findings suggest that individuals who have been vaccinated less frequently and have lower pre-vaccination antibody levels experience longer durations of effective protection (seroprotection) from the vaccine, with notable differences observed in antibody response to different influenza subtypes.*

Article Synopsis
  • There is a need for more research on neonatal behavior that applies to diverse global populations, but few appropriate assessment measures exist for use from birth.
  • The Neonatal Behavioural Assessment Scale (NBAS) was piloted in rural Gambia and showed great utility, leading to adaptations tailored to the local environment.
  • When comparing NBAS results between infants in the UK and The Gambia, findings indicated fewer state changes in Gambian infants and revealed associations with perinatal factors like pregnancy anxiety, suggesting cultural contexts impact early neurobehavioral development.

The complex dynamics of protein expression in plasma during hyperacute HIV-1 infection and its relation to acute retroviral syndrome, viral control, and disease progression are largely unknown. Here, we quantify 1293 blood plasma proteins from 157 longitudinally linked plasma samples collected before, during, and after hyperacute HIV-1 infection of 54 participants from four sub-Saharan African countries. Six distinct longitudinal expression profiles are identified, of which four demonstrate a consistent decrease in protein levels following HIV-1 infection.
