Immunization against pertussis was introduced in Sweden in the 1950s and discontinued in 1979. This was followed by a low endemic level of pertussis for 3 years. Thereafter the incidence gradually increased and there were two outbreaks in 1983 and in 1985. In the period 1980 to 1985 pertussis was confirmed by culture or serology in 36,729 patients of which 11% were younger than 12 months of age and 69% were ages 1 to 6 years. An estimate of the total frequency of pertussis in preschool children… Expand
Declining pertussis incidence in Sweden following the introduction of acellular pertussis vaccine.
TLDR
The data suggest that unimmunised infants and children who have received only one dose of pertussis vaccine were provided some protection, and the decline is most obvious from the second dose onwards and remained stable for 4-5 years after the third dose in the absence of any booster dose. Expand
Epidemiology of pertussis in French hospitals in 1993 and 1994: thirty years after a routine use of vaccination.
TLDR
The results strongly support the importance of adhering to the immunization schedule and suggest introducing booster dose(s) to prolong vaccine immunity and reduce the exposure to Bordetella pertussis of infants too young to be immunized. Expand
Mass vaccination of children with pertussis toxoid--decreased incidence in both vaccinated and nonvaccinated persons.
TLDR
Significant decreases in B. pertussis isolates and hospitalizations occurred in all age groups, including adults and nonvaccinated infants, and mass vaccination of children with pertussi toxoid decreases spread of B.pertussis in the population. Expand

TLDR
Growth of a susceptible adult population appears to be the primary factor contributing to the resurgence of pertussis in the United States; widespread immunization has reduced the potential for individuals to acquire exposure-induced immunity. Expand
Pertussis in South Australia 1893 to 1996.
TLDR
Despite no substantial increase in mortality nor hospitalisation for pertussis in South Australia, the notification rate has remained high since 1993, and this increase may be attributable to the use of more sensitive tests for pertussedis, such as serology. Expand
Persistence of pertussis in an immunized population: results of the Nova Scotia Enhanced Pertussis Surveillance Program.
TLDR
The surveillance program demonstrated that the incidence of pertussis in Nova Scotia, although among the highest in North America, is still underestimated, and increased the rate of laboratory confirmation from 17% to 65%, suggesting that strict clinical criteria accurately reflect accurately reflect incidence. Expand
Cumulative incidence of pertussis in an unvaccinated preschool cohort based on notifications, interview and serology
TLDR
Even this surveillance system, which yields the highest incidence rates, underestimates the incidence of the disease, according to serological methods and the national epidemiological surveillance system. Expand
Pertussis in hospitalized children.
TLDR
It is indicated that pertussis continues to be a cause of serious morbidity and mortality in infants in infants treated at Parkland Memorial Hospital and Children's Medical Center, Dallas, Tex. Expand
Pertussis after end of a mass vaccination project--end of the "vaccination honey-moon".
TLDR
A reemergence of pertussis was seen from the end of 1999 with a peak in 2004 followed by a decrease when booster doses to both 6 and 10 year old children were introduced in 2005-2006. Expand
Long-term Follow-up of Swedish Children Vaccinated With Acellular Pertussis Vaccines at 3, 5, and 12 Months of Age Indicates the Need for a Booster Dose at 5 to 7 Years of Age
TLDR
The increased incidence among 7- to 8-year-olds (ie, mainly acellular pertussis vaccine–vaccinated children) suggests waning of vaccine-induced protection from pertussi, and data suggest a booster dose of a cellular pertussedis vaccine is warranted from 5 to 7 years of age. Expand

TLDR
All available evidence indicates that pertussis vaccine use in both the United Kingdom and the United States was responsible for a drastic reduction in the magnitude of both endemic and epidemic pertussi. Expand
Pertussis disease, vaccine, and controversy.
TLDR
Pertussis vaccine was widely introduced in the 1950s and 1960s, and it has a high frequency of transient, nondamaging side effects, a lesser frequency of potentially serious adverse effects, and a remote risk of permanent neurological sequelae or death. Expand

TLDR
Though the recent decrease of the vaccine acceptance rate was due to the public reaction to rather imbalaanced arguments concerning the vaccine risk, it is also true that a more potent and less toxic component vaccine is urgently needed at this moment. Expand
Severity of whooping cough in England before and after the decline in pertussis immunisation.
TLDR
A comparison of admissions and deaths in England and Wales before and after the decline in immunisation suggests that several factors other than disease severity--a shift in the social class distribution of the disease, an increase in the proportion of milder cases notified, and improved care--were responsible for this.

TLDR
Until improved vaccines are available, continued use of the present vaccines, with careful attention to possible contraindications, seems the only prudent course to follow. Expand
Whooping cough and pertussis vaccine.
TLDR
In 1982 of the 22 sporadic cases, 11 occurred in August, two in September, and five in October, making a total of 18 of the sporadic cases (82%) occurring in the second six months of the year. Expand
Bordetella Pertussis Whole Cell Vaccines–Efficacy and Toxicity
TLDR
The pertussis‐associated mortality is currently very low in the industrialised countries and no differences can be discerned when countries with high, low and zero immunisation rates are compared. Expand
Whooping cough and whooping cough vaccine: the risks and benefits debate.
TLDR
The dangers of the disease outweigh any known hazards of the vaccine, and the authors conclude that whooping cough is less important a cause of death and disability at present, it remains a potentially lethal disease that should be controlled. Expand
