Promoting the Use of Modern Communication Tools to Increase Vaccine Uptake in Pregnancy

To the Editor The research article published by Skoff et al reported that, following maternal diphtheria toxoid and acellular pertussis vaccine introduction, a sustained decrease in pertussis incidence was observed in infants younger than 2 months. A slope of −14.53 per 100 000 infants per year from before to after implementation during pregnancy has been calculated. Modern approaches in prenatal communication may be relevant to this study.
