Arch Pediatr Adolesc Med ; In December , the FDA licensed the first diphtheria, tetanus toxoid, and acellular pertussis vaccine DTaP for use in children aged 15 months to 7 years.
In this study, the authors analyzed post-marketing surveillance data submitted to the Vaccine Adverse Event Reporting System VAERS between late and late to determine whether serious but uncommon adverse events are less frequent after DTaP as compared with whole-cell pertussis DTP vaccine receipt. An estimated 27 million DTP doses with or without Haemophilus influenzae type b vaccine and 5 million DTaP doses were administered during this period. DTaP was associated with significantly fewer total adverse event reports, as well as significantly fewer reports of subcategory adverse events fever, seizures or hospitalization , compared with DTP.
Risk of serious acute neurological illness after immunization with diphtheria-tetanus-pertussis vaccine. JAMA ; The authors prospectively identified children between mid and mid in Washington and Oregon states to evaluate the association between receipt of whole-cell pertussis vaccine and serious acute neurological illness within seven days of vaccination.
Severe reactions associated with diphtheria-tetanus-pertussis vaccine: detailed study of children with seizures, hypotonic-hyporesponsive episodes, high fevers and persistent crying. Pediatrics ; The authors prospectively evaluated children in Los Angeles, California, between and to determine causes and risk factors for severe DTP reactions within 48 hours of vaccine receipt. Children with seizures had a high rate of personal and family histories of seizures, and 90 percent had documented fevers.
Persistent crying was associated with painful local reactions. Neither lymphocytosis nor hypoglycemia occurred. No biologically active pertussis toxin was found in the acute sera of children experiencing possible severe DTP reactions. As acellular pertussis vaccines have less endotoxin, which is thought to lead to febrile seizures, the authors concluded that use of acellular vaccines should lead to a reduction in DTP-related seizures due to a decrease in febrile events.
Acellular pertussis vaccines also have lower local and systemic reaction rates compared with the whole cell vaccine utilized in this study; therefore, persistent crying may also be reduced. Risk of seizures and encephalopathy after immunization with the diphtheria-tetanus-pertussis vaccine.
The authors evaluated the risk of seizures and other neurological events, including encephalopathy, following DTP immunization in Denmark in more than 38, children who received about , DTP immunizations in the first three years of life. The authors found no increased risk of febrile or afebrile seizures in the 0- to three-day window following immunization when compared with 30 or more days after vaccine receipt. Two cases of encephalitis were reported, but onset occurred more than two weeks after vaccine receipt.
Griffith AH. Permanent brain damage and pertussis vaccination: is the end of the saga in sight? The author provides an overview of the pertussis vaccine and controversies surrounding its possible link to permanent brain damage. Reports of permanent brain damage thought secondary to receipt of the pertussis vaccine were published in the s through s.
Most notably, a case series suggesting permanent brain damage secondary to pertussis vaccination out of the National Hospital for Sick Children by Kulenkampff and colleagues was the subject of a United Kingdom television documentary in that resulted in a significant decline in vaccination rates and a consequent resurgence of pertussis in England. Repercussions from this documentary in the UK included the establishment of expert panels and sponsored research teams by the Department of Health and Social Security to examine existing clinical data and to carry out prospective studies including the North West Thames study see Pollock, et al, Lancet data reported below and the National Childhood Encephalopathy Study NCES.
The NCES evaluated reported cases of defined serious neurological disorders arising in children between 2 and 36 months of age admitted to the hospital between mid and mid in the UK.
These researchers estimated the attributable risk of neurological damage after pertussis immunization to be 1 in ,, injections, but the report was limited by certain structural biases and incomplete information; furthermore, these results could not be reproduced in subsequent studies. Regarding the Kulenkampff data, more than half of the cases either could not be linked to pertussis vaccination e.
Reexamination of the NCES data showed. Family history of convulsions and use of pertussis vaccine. J Pediatr ; The authors evaluated data from the CDC Monitoring System for Adverse Events Following Immunization during the period of to to determine the risk of neurologic events after vaccination with DTP in patients with a family history of convulsions compared with those without a family history.
Children with a family history of seizures had an increased risk of neurologic events, primarily febrile convulsions, after DTP receipt, but this increase in risk may reflect a nonspecific familial tendency for convulsions rather than a specific vaccine effect as well as selection bias. Given the rare occurrence of neurologic events after DTP vaccination, the generally benign outcome of febrile convulsions that accounted for more than 75 percent of the events, and the risk pertussis caused by not vaccinating people with a family history of convulsions, the authors concluded that a history of convulsions in a close relative should not be a contraindication to the pertussis vaccination.
Rather, prevention of post-vaccination fever may be warranted in these children. Infants and children with convulsions and hypotonic-hyporesponsive episodes following diphtheria-tetanus-pertussis immunization: follow up evaluation. Pediatrics ;81 6 In a previous prospective study Cody, et al Pediatrics , the authors found that minor reactions e. Among more than 15, DTP injections, nine children developed seizures and nine developed hypotonic-hyporesponsive episodes though no sequelae were detected following these possible temporal reactions.
The authors completed a follow-up evaluation six to seven years later in 16 of these children to determine if any had evidence of neurologic impairment too subtle to have been detected at the time of their initial evaluation. All 16 children were considered to be normal by their parents and — as determined by their school performance — had no evidence of serious neurologic damage.
Relationship of pertussis immunization to the onset of neurologic disorders: a retrospective epidemiologic study. The authors examined the temporal relationship between onset of neurologic disorders and the time of pertussis vaccine in children immunized with either DTP or monovalent pertussis at different ages. They found no relationship between the age of onset of epilepsy and scheduled age of administration of pertussis vaccine; however, a relationship existed between scheduled age of administration and first febrile seizure, which occurred more commonly with the third dose in the series between months of age.
No relationship between pertussis immunization and the occurrence of central nervous system infections was noted. Neurologic events following diphtheria-tetanus-pertussis immunization. Pediatrics ;81 3 The authors assessed the frequency of serious neurologic events following administration of , DTP immunizations in children between and They found no cases of acute unexplained encephalopathy temporally associated with vaccination.
The onset of one serious seizure disorder occurred within three days of immunization, with 1. The incidence of recorded febrile seizures in the immediate post-immunization period was 3. Infantile spasms and pertussis immunisation. Lancet ; The authors investigated the possible role of pertussis immunization and other factors in the etiology of infantile spasms reported to the National Childhood Encephalopathy Study between and in England, Scotland and Wales.
No significant association was found between infantile spasms and pertussis immunization in the 28 days following vaccination. Immunization against whooping cough: a neuropathological review. Neuropathol Appl Neurobiol ;9 4 The authors examined published data on childhood deaths which were thought to be due to receipt of the pertussis vaccine and identified an additional 29 children in England and Wales whose deaths between and had been reported as occurring in relation to DTP and had post-mortem examinations.
Deaths occurred within three weeks or up to 12 years after DTP receipt. Upon autopsy, various cerebral abnormalities were found; however, none of the cases in this study or in previous published reports had demonstrated a recurring pattern of inflammatory or other damage that could be accepted as a specific reaction to pertussis immunization. Reactive changes that were occasionally found appear to be indistinguishable from those seen in other infantile encephalopathies.
Pollock TM and J Morris. A 7-year survey of disorders attributed to vaccination in North West Thames Region. Lancet ;1 The authors examined the relationship between pertussis and other vaccines and neurological problems over a seven-year period. All children reported to have serious or unusual vaccine reactions, regardless of severity, had records investigated and were physically examined by an area health authority medical officer four weeks after the original report; and all children, except for those with mild symptoms, had a developmental examination six months after the report.
In a group of hundreds of thousands of children and more than , DTP immunizations, 20 reports of convulsions within three weeks of DTP were reported and three-quarters of the reports were febrile seizures within 48 hours of immunization; all children were developmentally normal on follow-up. Twelve neurological disorders were reported to have occurred within eight weeks of DTP receipt; 11 of which had either infantile spasms, infectious etiology, or epilepsy, none of which were linked to DTP.
The authors concluded that their study does not support the claim that DTP produces a syndrome characterized by a previously healthy child who presents with continuous screaming, collapse, convulsion and arrested mental development. Melchior JC. Infantile spasms and early immunization against whooping cough: Danish survey from to Arch Dis Child ; The authors examined the relationship between immunization and the onset of infantile spasms over a six-year period in Denmark after a change in its immunization program.
Previously, DTP vaccine had been administered at 5, 6, and 15 months of age, but was changed in to monovalent pertussis vaccine at 5 weeks, 9 weeks, and 10 months of age. The authors found no differences in the age at onset of infantile spasms between immunized and non-immunized children; half of all cases in each group began before 5 months of age despite children immunized before not receiving the first dose until 5 months of age.

Tetanus What is tetanus? Two populations most affected by tetanus In developed countries, tetanus is typically thought of as infecting wounds in adults who have injured themselves; however, in the developing world many infants suffer from neonatal tetanus.
Pertussis What is pertussis? Five things you should know about pertussis include: Pertussis is highly contagious; in fact, eight of 10 non-immune people will be infected when exposed to someone with the disease. Pertussis is commonly misdiagnosed and under-diagnosed. You can get pertussis more than once, and protection from the vaccine fades over time. Older children and adults commonly transmit pertussis to infants and young children. Pertussis can be particularly severe, even deadly, in infants.
Misdiagnosis, under-diagnosis, and fading immunity Experts are aware that the actual number of pertussis infections each year is much greater than the number diagnosed. Under-diagnoses: Because many adults who are ill do not go to the doctor, they are never diagnosed with pertussis. Fading immunity: Since there is a vaccine, people expect to be immune, but booster doses are needed to maintain immunity.
Susceptible infants Although a pertussis infection can interfere with day-to-day life, adults tend to recover. The result is that their babies receive a higher level of maternal antibodies against pertussis that can protect them if they are exposed to the bacteria before vaccination. Pregnant women should get the Tdap vaccine as early during this window of 27 to 36 weeks as possible to maximize the quantity of antibodies the baby may have at the time of birth.
Limited exposure — Anyone who is ill, particularly with symptoms that include coughing, should refrain from being near the baby. Family members who will be with the new infant for extended periods of time are also recommended to get a single dose of Tdap vaccine if they have not already had one.
DTaP, Tdap, and Td Vaccines The DTaP and Tdap vaccines both protect against three bacterial infections: diphtheria, tetanus and pertussis, whereas the Td vaccine only protects against diphtheria and tetanus. Tdap : The Tdap vaccine is different from the DTaP vaccine because it contains lesser quantities of diphtheria and pertussis proteins.
For this reason, Tdap is much less likely than DTaP to cause side effects such as pain, redness and tenderness in adolescents and adults. The Tdap vaccine is recommended for most people 11 years and older who have not previously received it. People due for a tetanus booster and those with a wound that warrants tetanus vaccination can get Tdap or Td vaccine.

There may be programs that can help you. Call the Family Health Hotline at or visit parenthelp website for more information. You can also contact your local health agency to find out if free vaccination clinics are planned in your community. The Centers for Disease Control and Prevention recommends that pregnant women get one Tdap vaccine at each pregnancy as early as possible between 27 and 36 weeks of gestation the third trimester.
Getting vaccinated while pregnant helps your baby in two ways: 1 the baby gets some short-term protection from your vaccination because you pass it to them before they are born; and 2 you reduce the risk of getting whooping cough yourself and exposing your newborn to to the infection. Women should be vaccinated during each pregnancy because the mother passes some protection to the baby before he or she is born, and because protection from Tdap is most effective within the first year after receiving the vaccine.
Whooping cough can be serious for infants, and most get it from parents, siblings, or caregivers. Getting the mother vaccinated at each pregnancy provides the best protection for each baby.
If you just gave birth and have never received Tdap the adolescent and adult whooping cough vaccine , you should get it right away. Your child will also need a fifth dose of DTaP vaccine between age four and six years.
Whooping cough is very serious for babies and young children, and the most common way for them to get it is from parents, caregivers, and other family members. The best way to protect your baby is to get the vaccine and make sure your other children are immunized on time. All family members living in your house and anyone who will spend time around your new baby—like grandparents and child care providers—should get the whooping cough vaccine if they have not already done so.
Check with your healthcare provider to make sure your family is up to date. It is safe to get Tdap while you're breastfeeding. Mothers vaccinated with Tdap may pass some whooping cough antibodies to their babies through breast milk, but it does not provide full protection.
It is still important to protect a baby who is still too young to be vaccinated by limiting his or her exposure to whooping cough. Ask people who are sick to stay away and make sure you and everyone who is around your baby is vaccinated. Then, as soon as your baby is old enough, get him or her vaccinated by following the recommended immunization schedule PDF. All healthcare workers should get one dose of Tdap vaccine. This helps protect the workers and their patients.
This is especially true if the health care worker will be working with babies and pregnant women. There is no state law that requires healthcare workers to get the whooping cough vaccine, but some health care organizations have policies that require staff to be vaccinated.
Check with your employer about your workplace vaccination policies. Yes, there were several cases of pertussis in healthcare workers during Washington's whooping cough epidemic. In Washington, whooping cough is a reportable condition and even a suspected case is supposed to be reported by healthcare professionals to their local health agencies. Some providers are unaware of the requirement to report.
Some cases of whooping cough are diagnosed as other conditions and aren't reported. An estimated one in 10 cases of whooping cough is reported to public health.

Who Which vaccine Adults 19 years and older who did not already get a Tdap booster Especially: Health care workers Anyone who is in contact with babies less than a year old Tdap; one dose Pregnant women even if you were previously vaccinated Tdap; one dose as early as possible during the third trimester between 27 and 36 weeks of gestation of each pregnancy Teens 11 to 18 years old preferably at 11 or 12 years of age Tdap; one dose Kids 7 to 10 years old who did not get all 5 doses of DTaP listed below Tdap; one dose Children 2 months to 7 years old DTaP One dose at each age: 2 months 4 months 6 months months years How soon can my new baby get the vaccine?
If your child is younger than seven years and isn't up to date, talk to his or her healthcare provider right away about getting caught up on DTaP vaccines.
Whooping cough can even lead to cracked ribs, pneumonia, or hospitalization. Whooping cough is most dangerous for infants younger than age 3 months. Many babies who get whooping cough are infected by older siblings, parents, or caregivers who might not even know they have the disease. Booster vaccines are needed throughout life, as protection from childhood vaccination wears off, putting adolescents and adults at risk for the infection.
B efore pertussis vaccines became widely available in the s, as many as , children got sick with whooping cough each year in the US and about 9, died as a result of the infection. In , the most recent peak year, CDC reported 48, cases of pertussis in the US, but many more cases go undiagnosed and unreported. It can be tough to diagnose because early symptoms may appear like the common cold or bronchitis. Whooping cough can be passed to vulnerable infants, those who have not yet received any or all of their vaccines.
Babies can get pneumonia, slowed or stopped breathing, or seizures convulsions. For babies, complications can be severe, even deadly. CDC recommends whooping cough vaccines for people of all ages. Whooping cough pertussis vaccine is given as a combination vaccine with the vaccines for diphtheria and tetanus.
