Adults who have not previously gotten the Tdap vaccine should receive a single dose. Although any time during this window is fine, public health personnel suggest earlier rather than later during the window for maximum protection for the baby. Read about a mom who lost her 3-week-old baby when they both got pertussis». Diphtheria is an extremely rare cause of disease in the United States.
Over the past 20 years there have been only about 15 cases of diphtheria and fewer than five deaths. The last death from diphtheria in the United States was in Most cases of diphtheria are imported; in fact, there have been no cases in U. On the other hand, the diphtheria vaccine has no serious side effects. So although the risk of disease and death from diphtheria is very small, the risk of severe adverse reactions or death from the diphtheria vaccine is zero.
In addition, drops in immunization rates in other parts of the world have taught us how quickly outbreaks of diphtheria can return. For these reasons, the benefits of the diphtheria vaccine outweigh its risks.
Although tetanus bacteria are everywhere, tetanus is an uncommon cause of disease in the United States. Between and , an average of 28 cases of tetanus was reported each year in the United States with three or four deaths.
On the other hand, although the tetanus vaccine can be a very rare cause of a short-lived allergic reaction called "anaphylaxis," the tetanus vaccine does not cause death. Therefore, the benefits of the tetanus vaccine outweigh its risks. In addition, because most of the disease and death from tetanus occur in the elderly, it is important to get booster immunizations every 10 years. This question is best answered by taking a look at the side effects of the old pertussis vaccine.
The old pertussis vaccine had a high rate of severe side effects such as persistent inconsolable crying, fever higher than degrees, and seizures with fever.
Due to negative publicity surrounding this vaccine, the use of the pertussis vaccine decreased in many areas of the world. For example, in Japan, children stopped receiving the pertussis vaccine by In the three years before the vaccine was discontinued, there were cases and 10 deaths from pertussis.
In the three years after the pertussis vaccine was discontinued, there were 13, cases and deaths from pertussis. It should be noted that although the side effects of the old pertussis vaccine were high, no child ever died from pertussis vaccine.
The Japanese Ministry of Health, realizing how costly its error had been, soon reinstituted the use of pertussis vaccine. The children of Japan proved that the benefits of the old pertussis vaccine clearly outweighed the risks. The new "acellular" pertussis vaccine has a much lower risk of severe side effects than the old "whole cell" vaccine. Pertussis is quite common in the United States.
An average of about 17, cases of pertussis were reported to the CDC each year between and , and a few people died from the disease in the U. However, because of under-diagnosis and misdiagnosis, the number of cases is likely to be a vast underestimate of that which actually occurred. Sadly, most of the deaths from pertussis occur in young infants who struggle to breathe against a narrowed windpipe, leading them to turn blue or stop breathing for a short time. Because the pertussis vaccine does not cause death, the benefits of the pertussis vaccine clearly outweigh its risks.
Risk of seizures after immunization in children with epilepsy: a risk interval analysis. BMC Pediatr ; The authors analyzed the risk of seizures after immunization in children with epilepsy less than 7 years of age. Nearly half of the immunization visits that occurred after epilepsy diagnosis were characterized by receipt of DTaP. The risk of seizures was not increased days after any vaccine.
The authors concluded that children with epilepsy do not appear to be at increased risk of seizures following immunization. These findings suggest that immunization is safe in children with epilepsy.
Seizures, encephalopathy, and vaccines: experience in the National Vaccine Injury Compensation Program. J Pediatr ; The authors described the demographic and clinical characteristics of children younger than 2 years of age for whom claims were filed with the National Vaccine Injury Compensation Program VICP alleging seizure disorder or encephalopathy or both during a one-year period.
In 80 percent of these claims, a pertussis-containing vaccine was implicated, and four times more often related to the whole-cell pertussis vaccine. Seizure disorder was the primary condition for which compensation was sought and less than half of the claimants were known to have been febrile at the time of presentation. A significant number of children with alleged vaccine injury had pre-existing neurologic or neurodevelopmental abnormalities.
Among those developing chronic epilepsy, many had clinical features suggesting that the epilepsy had a genetic basis. Vaccine ; The authors examined the risk of serious, but uncommon, adverse events after receipt of DTaP-IPV in more than , children years of age during a four-year period via the Vaccine Safety Datalink project. Risk of febrile seizures and epilepsy after vaccination with diphtheria, tetanus, acellular pertussis, inactivated poliovirus, and Haemophilus influenzae type b.
JAMA ; 8 The authors evaluated the risk of febrile seizures and epilepsy in more than , children who received DTaP-IPV-Hib at ages 3, 5, and 12 months in Denmark during a six-year period. DTaP-IPV-Hib vaccination was not associated with an increased risk of febrile seizures in children within seven days following receipt of vaccine compared with those children beyond seven days of vaccination.
Sub-analyses indicated an increased risk of febrile seizures on the day of the first two vaccinations, although absolute risk was small.
Lack of association between acellular pertussis vaccine and seizures in early childhood. Pediatrics ; 2 :ee The authors investigated the incidence of seizures following receipt of DTaP during a year period in more than , children aged 6 weeks to 23 months. They found no significant increase in the risk of seizures following receipt of DTaP.
An assessment of the safety of adolescent and adult tetanus-diphtheria-acellular pertussis Tdap vaccine, using active surveillance for adverse events in the Vaccine Safety Datalink. No evidence of an association between Tdap and any of these adverse events was found during a three-year-surveillance period that included more than , Tdap doses. GBS and cranial nerve sub-analyses found no statistically significant temporal clustering within 42 days after vaccination. Encephalopathy after whole-cell pertussis or measles vaccination: lack of evidence for a causal association in a retrospective case-control study.
Pediatr Infect Dis J ; The authors investigated the possible relationship between whole-cell pertussis DTP or measles MMR vaccination and encephalopathy, encephalitis, and Reye syndrome by evaluating 15 years of health records from four health maintenance organizations in the United States, which encompassed nearly 2.
DTP and MMR vaccines were not associated with an increased risk of encephalopathy, encephalitis, or Reye syndrome after vaccination. Additionally, a clinically distinctive pertussis vaccine-induced encephalopathy was not detected, which was consistent with other studies. Decrease in hospital admissions for febrile seizures and reports of hypotonic-hyporesponsive episodes presenting to hospital emergency departments since switching to acellular pertussis vaccine in Canada: a report from IMPACT.
Pediatrics ;ee The authors compared the incidence of hospital admissions for febrile seizures and hypotonic-hyporesponsive episodes HHEs presenting to hospital emergency departments before and after transition from DTP to DTaP in Canada. The risk of seizures after receipt of whole-cell pertussis or measles, mumps and rubella vaccines. N Engl J Med ; The authors investigated the relationship between DTP and MMR and the risk of a first seizure, subsequent seizures and neurodevelopmental disability in children.
Receipt of DTP vaccine was associated with an increased risk of febrile seizures only on the day of vaccination six to nine febrile seizures per , children vaccinated. Receipt of MMR vaccine was associated with an increased risk of febrile seizures eight to 14 days after vaccination febrile seizures per , children vaccinated. Children with febrile seizures after vaccination were not found to be at a higher risk for subsequent seizures or neurodevelopmental disabilities as compared with their unvaccinated counterparts.
The authors concluded that the increased risk of febrile seizures secondary to DTP and MMR do not appear to be associated with any long-term, adverse consequences. Vaccination of children following a previous hypotonic-hyporesponsive episode. J Paediatr Child Health ; Hypotonic-hyporesponsive episodes HHE were once considered a contraindication to pertussis vaccination in Australia.
In this study, the authors evaluated the safety of further vaccination in children who had experienced an HHE 95 percent experienced with whole-cell pertussis and 80 percent after the first dose. The authors concluded that previously healthy children who experience HHE reactions can safely continue standard vaccination schedules. Rate of recurrent collapse after vaccination with whole cell pertussis vaccine: follow up study. BMJ ; The authors conducted a follow-up study of 84 children in the Netherlands with reported collapse after their first whole cell pertussis vaccination DTP to determine the rate of recurrence in those who received subsequent doses of DTP.
None of the children had recurrent collapse, and other adverse events were only minor. A controlled trial of two acellular vaccines and one whole cell vaccine against pertussis. The authors compared the efficacy and safety of two acellular pertussis vaccines with whole-cell pertussis and DT alone in more than 14, children within six to 28 weeks of life. Seizures were either infrequent or did not occur in the vaccine groups.
A controlled trial of a two-component acellular, a five-component acellular, and a whole-cell pertussis vaccine. The authors compared the efficacy and safety of a two-component acellular pertussis vaccine, a five-component acellular pertussis vaccine, a whole-cell pertussis and DT alone in more than 9, children within the first six months of life. DTP was found to have a significantly higher rate of local and systemic reactions, including protracted crying, cyanosis, fever, and local reactions compared with both DTaP vaccines and DT.
DTaP rates of these events were similar to the control group who received DT alone. Seizures occurred infrequently in the 48 hours after any vaccine receipt, and rates were similar among all groups.
The safety of acellular pertussis vaccine vs whole-cell pertussis vaccine. 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. Learn More Related Issues Specifics.

It is for older children and adults. DT prevents diphtheria and tetanus. It is for children younger than seven who cannot tolerate the pertussis vaccine. Td prevents diphtheria and tetanus. Since then, there has been a slow but steady increase in reported whooping cough cases. There are several reasons likely contributing to this increase:.
The bacteria that cause pertussis are also always changing at a genetic level. Research is underway to determine if any of the changes are having an impact on public health. However, the latest studies suggest that pertussis vaccines continue to be effective despite recent genetic changes.
In the s, the United States switched from whole cell to acellular whooping cough vaccines for babies and children. Acellular whooping cough vaccines have fewer side effects, but do not appear to protect for as long.
In general, DTaP is effective for 8 or 9 in 10 children who get it. Among children who get all 5 shots of DTaP on schedule, effectiveness is very high. The vaccine protects nearly all children 98 in within the year following the last shot.
About 7 in 10 kids are fully protected 5 years after getting their last shot of DTaP. The other 3 in 10 kids are partially protected and are less likely to have serious disease if they do get whooping cough. In the first year after getting the vaccine, Tdap protects about 7 in 10 people.
There is a decrease in effectiveness in each following year. The vaccine fully protects about 3 or 4 in 10 people 4 years after getting Tdap.
A CDC evaluation found Tdap vaccination during the third trimester of pregnancy prevents more than 3 in 4 cases of whooping cough in babies younger than 2 months old.
For babies who do get whooping cough, 9 in 10 are protected from infections serious enough to need treatment in a hospital if their mother received Tdap during pregnancy.
Learn more about DTaP waning immunity and whooping cough outbreaks. Most people who get a vaccine that helps protect against diphtheria, tetanus, and whooping cough do not have any serious problems with it. With any medicine, including vaccines, there is a chance of side effects.
These are usually mild and go away on their own within a few days, but serious reactions are possible. Reactions where the healthcare professional gave the shot and fever occur more often after the fourth and fifth doses of the DTaP series than after earlier doses. Sometimes the entire arm or leg that the shot was given in swells after the fourth or fifth dose.
If this happens, the swelling lasts between 1 and 7 days. These vaccines are part of the routine childhood immunization schedule. Therefore, they are regularly available for children at:. Locate one near you. You can also contact your state health department to learn more about where to get vaccines in your community. When receiving any vaccine, ask the provider to record the vaccine in the state or local registry, if available.
This helps healthcare professionals at future encounters know what vaccines you or your child have already received. Medicare Part D plans cover Tdap vaccine, but there may be costs to you depending on your specific plan.
Most private health insurance plans cover these vaccines.
