However, the disease continues to play a role globally. In , countries reported more than 16, cases to the World Health Organization, but many more cases likely go unreported. Studies estimate that diphtheria toxoid-containing vaccines protect nearly all people 95 in for approximately 10 years. Protection decreases over time, so adults need to get a Td or Tdap booster shot every 10 years to stay protected.
The United States introduced the first tetanus-toxoid containing vaccine into the routine childhood immunization schedule in the late s. At that time, states reported between and cases each year. Tetanus infections steadily declined after the vaccination recommendation. Today, tetanus is uncommon in the United States, with an average of 30 reported cases each year. Studies estimate that tetanus toxoid-containing vaccines protect essentially all people for approximately 10 years.
Whooping cough vaccines became widely available in the s. Before then, about , children got sick and about 9, died from whooping cough each year in the United States. After vaccine introduction, whooping cough cases reached an all-time low in the s.
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. If you or your child is sick at the scheduled time, the vaccination may be delayed. Vaccines are a safe and effective way to protect against a disease. Both DTaP and Tdap protect against diphtheria, tetanus, and whooping cough. Babies and children under age 7 get DTaP.
Adults and children over age 7 get Tdap. If you have any questions or concerns, make sure to discuss them with your doctor. What may seem like a normal cold to you could actually be whooping cough. Learn why you can still get this contagious disease, even if you were….

What is the recommended timeline for getting DTaP and Tdap? Is DTaP or Tdap recommended during pregnancy? Approximately 1 in 10 U. An increase in the number of reported deaths from pertussis among very young infants has paralleled the increase in the number of reported cases.
Reasons for the increases in pertussis are not completely clear; however, multiple factors have likely contributed to the increase, including waning immunity from the pediatric acellular vaccine DTaP , increased recognition of pertussis, and improved diagnostic testing and reporting. Can a child or an adult who has had pertussis get the disease again?
Reinfection appears to be uncommon, but does occur. Reinfection may present as a persistent cough rather than typical pertussis. Should further doses of pertussis vaccine be given to an infant or child who has had culture-proven pertussis?
Immunity to pertussis following infection is not life-long. Persons with a history of pertussis should continue to receive pertussis-containing vaccines according to the recommended schedule. If an adolescent or adult who has never received their one-time dose of Tdap is either infected with or exposed to pertussis, is vaccination with Tdap still necessary, and if so when?
Adolescents or adults who have a history of pertussis disease generally should receive Tdap according to the routine recommendation. This practice is recommended because the duration of protection induced by pertussis disease is unknown waning might begin as early as 7 years after infection and because diagnosis of pertussis can be difficult to confirm.
Administering pertussis vaccine to people with a history of pertussis presents no theoretical risk. For details, visit CDC's published recommendations on this topic at www. If a healthcare worker HCW receives tetanus-diphtheria-acellular pertussis Tdap vaccine and is then exposed to someone with pertussis, do you treat the vaccinated HCW with prophylactic antibiotics or consider them immune to pertussis?
You should follow the post-exposure prophylaxis protocol for pertussis exposure recommended by CDC see www.
Research is needed to evaluate the effectiveness of Tdap to prevent pertussis in healthcare settings. Until studies define the optimal management of exposed vaccinated healthcare personnel, or experts arrive at consensus, healthcare facilities should continue to follow the post-exposure prophylaxis protocol for vaccinated HCWs who are exposed to pertussis. A vaccinated health care provider exposed to pertussis still needs antimicrobial chemoprophylaxis if they are likely to expose patients at risk for severe pertussis e.
If a person received a Tdap vaccine and then had a positive pertussis PCR two weeks later, could it be a false positive from the vaccine or should we consider this a case of pertussis? Recent Tdap vaccination does not affect PCR testing. PCR tests are very sensitive and could give a false positive result for other reasons. For more information on the interpretation of pertussis diagnostic tests, see www. The document can be accessed on the CDC website at www.
What are the recommendations for vaccination of infants and young children with DTaP? The fourth dose may be given as early as age 12 months if at least 6 months have elapsed since the third dose. What are the recommendations for use of Tdap in children and adults age 7 and older?
As stated above, Tdap can be administered regardless of interval since the previous Td dose. If needed, they should complete their series with Td or Tdap. If a Tdap dose is administered at age 10 years or older, the Tdap dose may count as the adolescent Tdap dose.
Women who have never received Tdap and who do not receive it during pregnancy should receive it immediately postpartum. As a pediatrician, I am concerned about protecting my newborn patients from pertussis, especially given the recent outbreaks in my community where infants have died. How many doses of pediatric diphtheria-tetanus-acellular pertussis DTaP vaccine does an infant need before she or he is protected from pertussis?
Efficacy data following just 1 or 2 doses are lacking but are likely lower. Therefore, it is especially important that you advise parents of infants and all people who live with the infant or who provide care to him or her be protected against pertussis. My year-old patient received a dose of Tdap when he was 7 years old. He also received a dose of Td 6 months later in order to finish a primary series of tetanus-toxoid.
Can I give him a dose of Tdap now? A year-old refugee's record indicates 2 doses of Td separated by 1 month and 1 dose of Tdap given 4 months after the second Td. Is he up to date? The first two doses of Td are valid because they are separated by at least 4 weeks. However, the minimum interval between the second and third doses of tetanus- containing vaccine is 6 calendar months.
So, the Td component of the Tdap dose is not valid because it was given only 4 months after the second dose. The pertussis component can be counted as valid. The patient should receive another dose of Td or Tdap 6 months after the invalid Tdap dose. My 7-year-old patient has had only 1 dose of tetanus toxoid-containing vaccine at 11 months of age a dose of DTaP. The catch-up schedule says he needs 3 additional doses of tetanus toxoid-containing vaccine 4 total.
Why 4? If he were completely unvaccinated on the seventh birthday, he would only need a total of 3 doses. If the first dose of a tetanus toxoid-containing vaccine is administered before the first birthday, 4 doses are necessary before beginning the year cycle of booster doses.
If the first dose is administered after the first birthday, 3 doses are necessary. The final dose should be spaced 6 months from the previous dose. Someone who received a dose of Tdap at age 11 or 12 years should receive a booster dose of Td or Tdap vaccine ten years later, unless tetanus prophylaxis is required sooner due to an injury or if Tdap vaccination is needed during pregnancy. Aren't the ACIP recommendations for use of Tdap vaccine in children ages 7 through 9 years and in adults age 65 years and older different from what is on the package inserts?
We have a year-old patient who states she had tetanus as a child. She does not know whether she ever had any tetanus-containing vaccines in her lifetime.
Should Tdap be given to this patient, and is it safe? A history of tetanus disease is not a reason to avoid tetanus-containing vaccines. Tetanus disease does not produce immunity because of the very small amount of toxin required to produce illness. As long as your patient has no other contraindications she should receive Tdap now.
My year-old patient inadvertently received a dose of Td instead of Tdap. He received a 5-dose series of DTaP in childhood. Do I need to wait a specific interval before giving him Tdap? Tdap should be administered as soon as possible. Should we give her another dose of Tdap when she reaches 27 weeks gestation? The Advisory Committee on Immunization Practices does not recommend Tdap more than once during a pregnancy. The Tdap she received earlier in pregnancy may not provide optimal protection from pertussis for the infant, but some protection is expected.
More information can be found at www. Vaccine Products Back to top I'm confused about the various vaccines that contain tetanus, diphtheria, and pertussis. Can you explain? There are two basic products that can be used in children younger than age 7 years DTaP and DT and two that can be used in older children and adults Td and Tdap.
Here's a hint to help you remember. This is indicated by an upper-case "D" for the pediatric formulation i. The amount of tetanus toxoid in each of the products is equivalent, so it remains an upper-case "T. There are two different DTaP products currently used in the U. ACIP has recommended that, whenever feasible, healthcare providers should use the same brand of DTaP vaccine for all doses in the vaccination series.
If vaccination providers do not know or have available the type of DTaP vaccine previously administered to a child, any DTaP vaccine may be used to continue or complete the series. For vaccines in general, vaccination should not be deferred because the brand used for previous doses is not available or is unknown see the ACIP's General Best Practices Guidance for Immunization at www.
What should we do if we don't know which brand of DTaP a child had previously? If the DTaP brand used for previous doses is not known or not in stock, use whatever DTaP vaccine you have available for all subsequent doses. Someone gave Tdap to an infant instead of DTaP. Now what should be done? If Tdap was inadvertently administered to a child under age 7 years, it should not be counted as either the first, second, or third dose of DTaP.
The dose should be repeated with DTaP. Continue vaccinating on schedule. If the dose of Tdap was administered for the fourth or fifth DTaP dose, the Tdap dose can be counted as valid. Please remind your staff to always check the vaccine vial at least 3 times before administering any vaccine.
In this situation, a second dose of Tdap should be administered at the recommended age of 11 or 12 years. We would like to avoid stocking both Tdap and Td vaccines. The updated ACIP recommendations for the use of Tdap vaccine state that Tdap or Td may be used in any situation where Td only was previously recommended.
The updated guidelines are available at www. I have a patient who received single-antigen tetanus TT in the emergency room rather than Td or Tdap. Should he be revaccinated? ACIP recommends that patients needing prophylaxis against tetanus always be given either Td or Tdap rather than TT, as long as there is no contraindication to the other vaccine components. If it's already been given and the person had not yet received Tdap as an adolescent or adult, you should make certain that he gets Tdap as soon as feasible.
If he had received Tdap previously, he can wait until the next scheduled booster dose is due to get his routine Td or Tdap booster. When should a person receive tetanus toxoid TT alone? Single antigen tetanus toxoid should only be used in rare instances, for example when a person has had a documented severe allergic response to diphtheria toxoid. In what year did tetanus toxoid first become available? At what age might most patients never have received a primary series? Tetanus toxoid became commercially available in , but was not widely used until the military began routine vaccination in Routine administration of tetanus toxoid was recommended by the AAP in Most World War II military personnel received at least one dose of tetanus toxoid, but civilian use, particularly for adults, did not increase until after the war.
You should not assume the tetanus vaccination status for any person based on their age alone. Only a written record is acceptable proof of immunization. People without documentation should be assumed to be unimmunized. If a dose of DTaP or Tdap is inadvertently given to a patient for whom the product is not indicated e.
Repeat with DTaP as soon as feasible. Note that DTaP is neither approved nor recommended for person older than 6 years except hematopoietic stem cell transplant recipients in some situations; see www. Does the dose of DTaP count? The DTaP in the Pentacel can be counted.
Although Pentacel is licensed as a 4-dose series and this may represent a fifth dose of Pentacel in which case it would be off-label use , the dose of DTaP counts as the fifth dose of DTaP. Both of these vaccines provide protection against diphtheria, tetanus, and pertussis. Boostrix GSK is licensed for people ages 10 years and older, and Adacel Sanofi Pasteur is licensed for people ages 10 through 64 years.
The two vaccines also contain a different number of pertussis antigens and different concentrations of pertussis antigen and diphtheria toxoid.
I am confused about which adults to vaccinate with Tdap vaccine and which product to use. Please help! ACIP recommends that all adults age 19 years and older who have not yet received a dose of Tdap receive a single dose. Tdap should be administered regardless of interval since the last tetanus or diphtheria toxoid-containing vaccine e. After receiving Tdap, people should receive Td or Tdap every 10 years for routine booster immunization against tetanus and diphtheria, according to previously published guidelines.
Pregnant women should receive Tdap during each pregnancy, preferably early in the 27 through 36 week gestation time period. Providers should not miss an opportunity to vaccinate adults age 65 and older with Tdap. Although a pertussis infection can interfere with day-to-day life, adults tend to recover. Unfortunately, infants and young children with narrow windpipes are not always as lucky.
Coughing episodes caused by pertussis often cause babies to turn blue as they struggle to breathe. Sadly, some of them do not survive.
Because the most negatively impacted age group is infants, who are too young to get a vaccine, public health officials have recommended two ways to protect them in the interim:. 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. In addition, the vaccines vary in terms of who should receive them and the quantities of vaccine proteins they contain:.
The bacteria that causes diphtheria makes a harmful protein, called a toxin. People who develop an immune response to this toxin are protected against the disease. The diphtheria vaccine is made by taking the diphtheria toxin and inactivating it with a chemical. The inactivated toxin is called a "toxoid. The diphtheria vaccine can cause mild side effects such as pain or soreness in the local area of the shot and occasionally a low-grade fever.
The bacteria that causes tetanus makes a harmful protein, called a toxin. The name of the tetanus toxin is tetanospasmin. People who develop an immune response to this toxin are protected against tetanus. The tetanus vaccine is made by taking the tetanus toxin and inactivating it with a chemical. Like the diphtheria vaccine, the tetanus vaccine can cause mild side effects such as pain or soreness in the local area of the shot and occasionally a low-grade fever. The tetanus vaccine is also a rare cause of a severe allergic reaction.
It is estimated that this allergic reaction could occur in about one of every 1 million children who receive the tetanus vaccine, and could include hives, difficulty breathing or a lower blood pressure.
The allergic reaction can be treated with medications. The bacteria that cause pertussis make several harmful proteins, called toxins. People who develop an immune response to some of these toxins are protected against disease. The pertussis vaccine is made by taking two to five of these toxins and inactivating them with a chemical.
The inactivated toxins are called "toxoids. The latest version of the pertussis vaccine was released in the fall of This vaccine is called the "acellular" pertussis vaccine or aP and is purer than the old "whole cell" pertussis vaccine. The "old" pertussis vaccine still contained a killed form of the whole pertussis bacteria. Because individual bacteria are sometimes called cells, the "old" pertussis vaccine was called the "whole-cell" vaccine. On the other hand, the new pertussis vaccine takes advantage of advances in protein chemistry and protein purification.
Because the whole killed pertussis bacteria are no longer present, the "new" pertussis vaccine is called the "acellular" vaccine. The "old" pertussis vaccine, called the "whole cell" vaccine, had a high rate of mild and severe side effects.
Mild side effects such as pain and tenderness where the shot was given, fever, fretfulness and drowsiness occurred in as many as one-third to one-half of children who received the vaccine. Severe side effects, such as persistent, inconsolable crying occurred in one of every doses, fever greater than degrees occurred in one of every doses, and seizures with fever occurred in one of every 1, doses.
The new "acellular" pertussis vaccine, the one that has been in use in the United States since , has much lower rates of both mild and severe side effects. Mild side effects such as pain and tenderness at the injection site occur in about one-third of children, most often after the fourth or fifth dose. More severe reactions occur in about one of every 10, children.
Severe reactions can include fever of degrees or higher, fever-associated seizures, inconsolable crying, or hypotonic-hyporesponsive syndrome, a condition in which a child can become listless and lethargic with poor muscle tone for several hours. Unfortunately, recent data suggests that the tradeoff for increased safety was decreased vaccine effectiveness.
However, it is unlikely that we would return to using the older version; instead, additional booster doses may be recommended until a newer version of the vaccine that is both safe and more effective can be developed. Because pertussis, in particular, circulates in many parts of the country each year and young infants are most susceptible to complications from the disease, the relative benefits of the vaccine may still outweigh the risks.
Previous experience has shown that in most cases, infants who experience inconsolable crying after the first dose of DTaP do not experience the same reaction after subsequent doses. Pertussis is common in teenagers and adults. Therefore, a vaccine to prevent pertussis in teenagers and adults is of great benefit.
A newer "acellular" pertussis-containing vaccine is available for older children and adults part of the Tdap vaccine. Because adolescents and adults can transmit this disease to infants who are too young to have received their series of the DTaP vaccine, it is imperative that adults around the baby are immune.
Parents, grandparents and childcare providers should all have received a dose of Tdap vaccine. Also see vaccine considerations for new and expectant moms. Pertussis can be a dangerous disease for a new baby. Because of their small airways and the amount of mucus caused by infection with pertussis, babies have trouble breathing, often turning blue during their coughing spells. Every year in the U. There are several things that you can do to help protect your baby from pertussis.
Babies get a vaccine to protect them from pertussis when they are 2 months, 4 months, and 6 months of age. They get an additional dose at 15 to 18 months. However, babies are most susceptible during their first few months of life either because they have not gotten the vaccine yet or because the dose they received did not fully protect them. During this time, you can protect your baby by making sure that all of the adults or siblings who will be around the baby are up to date on pertussis vaccine and are healthy, particularly that they are free of coughing illnesses.
There is a vaccine available for adolescents and adults called Tdap. The "p" means that it contains a pertussis component. Although any time during this window is acceptable, public health officials recommend getting the vaccine as early as possible during this window.
If you are past 36 weeks in your pregnancy, be sure to ask for the Tdap vaccine before being discharged from the hospital. Your spouse, the baby's grandparents and any other adults who will commonly be around the baby should also get the vaccine in advance of your delivery if they have not had a dose previously.
Additionally, you can encourage hand washing before people touch the baby, and if anyone has a cough, try to limit the baby's exposure to this person. Unfortunately, people are not only contagious in the first few weeks of the severe coughing stage, but also in the one- to two-week period leading up to cough onset.
During this period, symptoms may resemble cold-like respiratory symptoms e. Read more about ways to protect your baby before vaccinations. Protection after a pertussis infection is not life-long. Because infants are at increased risk of suffering complications and death from pertussis infections, adults and teens who will be around them, including childcare providers, should have a single dose of the Tdap vaccine.
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.
