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.

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.

Menopause and memory: Know the facts. How to get your child to put away toys. 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. Complications from tetanus vaccinations are extremely rare, and the disease itself poses far more risks than the vaccine. If you think you or your child may be having an allergic reaction to the vaccine, seek immediate medical help.
Signs of an allergic reaction may include:. The spores of the bacteria live in soil, dust, saliva, and manure. If an open cut or wound is exposed to the spores, they can enter your body. Once inside the body, the spores produce toxic bacteria that affects muscles and nerves. Tetanus is sometimes called lockjaw because of the stiffness it can cause in the neck and jaw. The most common scenario for catching tetanus is stepping on a dirty nail or sharp shard of glass or wood that pierces through the skin.
The time between exposure to tetanus and the appearance of symptoms ranges between a few days to a few months. Most people with tetanus will experience symptoms within 14 days of exposure. Tetanus can be fatal. The Immunization Action Coalition states that about 10 percent of reported cases have led to death. You can manage symptoms by using sedatives to control muscle spasms. Most treatment consists of trying to reduce exposure to the toxins produced by the bacteria.
To do that, your doctor may advise:. Tetanus is a potentially deadly disease, but it can be prevented by staying up-to-date on your vaccine schedule and getting boosters every 10 years.
