SUMMARY
More recent studies show that by 5 years after completion of a DTaP series, children were up to 15 times more likely to acquire pertussis compared to the first year after the series. Studies have also documented rapid decline in pertussis antibodies within as few as 2–3 years of the most recent aP vaccination, often to pre-vaccination levels and although antibody levels alone are not necessarily indicative of waning immunity, in this case given the higher risk of infection after aP vaccine with time, it is strongly suggestive of it.”
