Pertussis (whooping cough)
This work is part of the NIHR-funded MEMVIE project.
Pertussis is a highly infectious respiratory illness, caused by the bacterium Bordetella pertussis. Its main symptom is bouts of uncontrollable, violent coughing, giving it the nicknames "whooping cough" and "the hundred-day cough". It is particularly dangerous for infants, and can be fatal for newborn babies. A vaccination program has been in place in the UK for sometime now, the vaccine given along with those for tetanus and polio, as the DTP vaccine.
There was a large spike in the number of pertussis cases in 2012; it is thought that this was caused, at least in part, by a reduction in childhood vaccination in the 1970's after a vaccine scare over the possible side-effects of the vaccine. Following this a maternal vaccination scheme was implemented in 2012/13, to confer vertical immunity to newborn babies from the mother.
Early work by the MEMVIE team examined the likely impact and cost-effectiveness of additional "cocooning" strategies, where other household members are vaccinated to protect newborn infants. We have performed a cost-effectiveness analysis of this strategy, compared with the maternal vaccination program already in place, and shown that it offers limited benefit and is not cost-effective. This work has been presented to JCVI and a manuscript has been submitted to Archives of Disease in Childhood.
