Maternal influenza and pertussis vaccination is an important strategy to reduce morbidity and mortality in infants. Previous vaccine safety studies have mostly focused on the association between maternal vaccination and fetal death.
Small volume assays are required for large-scale research studies and in particular paediatric trials, where multiple measures are required from a single sample. Fluorescent bead-based technology (Bioplex/Luminex) allows high through-put and simultaneous quantification of multiple analytes in a single test. This technology uses sets of microspheres, each with a unique spectral address that can be coated with a different antigen of interest.
A birth acellular pertussis vaccine may be a valuable alternative for immunity against infant pertussis when a pregnancy pertussis vaccine has not been administered. We assessed whether a birth dose may impair immunoglobulin G (IgG) responses to childhood pertussis boosters.
We assessed the impact of maternally derived pertussis antibodies on infant responses to a 2 + 1 vaccine schedule (6 weeks, 12 weeks, and 12 months). Infants with baseline antibodies showed lower IgG responses following the primary vaccination series, but this did not impair booster responses at 4 years of age.
Vaccination is the injection of an inactivated bacteria or virus into the body. This simulated infection allows an individual's immune system to develop an adaptive immunity for protection against that type of illness. When a sufficiently large percentage of a population has been vaccinated, this results in herd immunity.
We compared the effect of a heterologous wP/aP/aP primary series (hereafter mixed wP/aP) versus a homologous aP/aP/aP primary schedule (hereafter aP-only) on antibody responses to co-administered vaccine antigens in infants and toddlers.
Toddlers will now get an additional whooping cough vaccine to protect them against the potentially deadly disease.
An extra whooping cough vaccination for babies comes as a result of work by researchers at the Wesfarmers Centre of Vaccines and Infectious Diseases.
Governments should rethink strategies to prevent whooping cough in newborn infants, including booster vaccination of close contacts of the baby.
