So on DTaP vaccination did you know. Because of the small number of antigens (3-5 in DTaP vaccines vs >3000 in DTwP vaccines), linked-epitope suppression occurs. Because of linked-epitope suppression, all children who were primed by DTaP vaccines will be more susceptible to pertussis throughout their lifetimes, and there is no easy way to decrease this increased lifetime susceptibility. Read that again. All children who were primed by DTaP vaccines will be more susceptible to pertussis throughout their lifetimes. Read the research paper here: https://pubmed.ncbi.nlm.nih.gov/30793754/
