Vaccinating pregnant women against pertussis at least one week before delivery was found to be 91% effective in preventing the disease in infants <3 months old and 95% effective in preventing infant deaths in a study conducted in England over a 3-year period following the introduction of dTap-IPV vaccine for pregnant women. Of the 37 deaths from pertussis in infants that occurred in England from 2009 to 2015, 32 (86%) were in infants <2 months of age, highlighting the vulnerability of very young infants to severe pertussis. All but 2 of the deaths in <2 month olds were in children whose mothers hadn’t been vaccinated against pertussis during their pregnancy, while in the 2 other cases, the vaccination occurred too late in the pregnancy (<10 days before the birth).

Rotavirus vaccination programs show significant short-term return on investments
In a UK cost-effectiveness analysis, which takes into account herd effect, the budget impact analysis demonstrated that the introduction of a rotavirus vaccine program could pay back between 58-96% of the cost outlay for the program within the first 4 years.
Measles infection suppresses the immune system for up to 3 years after infection
In a study of data from England & Wales, Denmark, and the US, it was shown that measles infection suppresses the immune system for up to 3 years after infection, increasing the risk of death due to other childhood infections during that time. This means that prevention of measles significantly impacts overall health during critical childhood years.
