To present an inventory of notifications of serious local reactions after revaccination of 4-year-old children with DaPT-IPV (diphtheria vaccine, acellular pertussis vaccine, tetanus vaccine and poliomyelitis vaccine), who had been vaccinated as a toddler with whole-cell pertussis combination vaccine (DwPT-IPV-Hib) and/or (from 2005 onward) with the acellular pertussis combination vaccine (DaPT-IPV-Hib).
Descriptive inventory
Via an enhanced passive surveillance system professionals and private individuals can report an adverse event following vaccination within the Dutch national vaccination programme. The number of notifications of local side effects was related to the total number of vaccinated children registered in Praeventis, a national vaccination register in which information on an individual level is available.
In 2008, we received an increasing number of notifications of serious local reactions after the revaccination of 4-year-olds with acellular DPT-IPV (average 3 per 1000 vaccinated children) with a peak in October/November. These children had also been vaccinated with acellular pertussis vaccine as infants. The symptoms of swelling and redness of sometimes the entire upper arm arose mostly the day after the vaccination and disappeared within 4 to 5 days without sequelae.
Although the mechanisms underlying these serious local reactions are still not well understood, they do not imply an acute allergic reaction or infection and so medication against such reactions is not usually necessary.
