Immunological parameters of the blood were studied in intranasal revaccination with a live measles vaccine (LMV) from the strain L-16. Alongside with specific immune response, LMV was shown to produce nonspecific changes in the system of immunocompetent cells the amount and duration of which were vaccine dose-dependent. The immunomodulating activity of LMV administered by different routes was different. Especially marked was the difference in the degree of side effect of the vaccine on T-lymphocytes. A dose of 10,000 TCD50 in 0.5 ml of LMV produced sufficient antigenic stimulation by the intranasal route of revaccination being quite satisfactory from the point of view of immunological safety of measles vaccine.

An effective live zoster vaccine has been widely used around the world. Although no deaths occurred in the original large clinical trial, we analyzed 10 serious adverse events, including six deaths that have subsequently occurred in four countries. The goal is to define the viral pathogenesis of these unexpected adverse events secondary to a viremia with dissemination of the vaccine virus.

Objective: To describe the polio vaccination status in 26 state capitals, the Federal District, and 12 municipalities in Brazil, among children born between 2017 and 2018.
Methods: This was a population-based household survey conducted from 2020 to 2022, which assessed polio vaccination coverage in children, considering valid, administered, and timely doses by municipality.
Results: Data were collected from 37,801 children.
Enhanced D614G and Omicron Variants Antibody Persistence in Infants at 2 Months of Age Following Maternal mRNA Booster Vaccination During Pregnancy or Postpartum.

Background: Following maternal COVID-19 vaccination, the persistence of antibodies in sera and breast milk for mothers and infants is not well characterized. We sought to describe the persistence of antibodies through 2 months after delivery in maternal and infant serum and breast milk following maternal COVID-19 mRNA vaccination and to examine differences by receipt of booster dose during pregnancy or postpartum.
Methods: This is a prospective cohort study with enrollment from July 2021 to January 2022 at 9 US academic sites.

Maternal immunization is an important tool directed against a variety of infectious maladies in the offspring. A complementary, but less explored area is the use of maternal immunization in the prevention and treatment of childhood cancers. This in part stems from the lack of adequate experimental model systems.
