In studies showing how well the whooping cough component works for children who get all five doses, DTaP fully protects:. In studies showing how well the whooping cough component works when women get Tdap during pregnancy, the vaccine protects:.
In general, diphtheria, tetanus, and whooping cough vaccines work well, but cannot prevent all cases of these serious diseases. Below is information about how well each of the vaccines work against each disease.
Diphtheria was once a major cause of illness and death among children. The United States recorded , cases of diphtheria in , resulting in 15, deaths. Starting in the s, diphtheria rates dropped quickly in the United States and other countries that began widely vaccinating.
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. In the first year after getting the vaccine, Tdap protects about 7 in 10 people.
Toxins produced by this bacterium can make it difficult to breathe and swallow, and can also damage other organs such as the kidneys and heart. Tetanus is caused by the bacterium Clostridium tetani , which lives in the soil, and can enter the body through cuts and burns. Toxins produced by the bacterium cause serious muscle spasms, which can affect breathing and heart function. Pertussis , or whooping cough, is caused by the bacterium Bordetella pertussis, and is very contagious.
Infants and children with pertussis cough uncontrollably and struggle to breathe. There are two other vaccines that protect against these infectious diseases — the Tdap vaccine and the DTP vaccine.
The Tdap vaccine contains lower quantities of the diphtheria and pertussis components than the DTaP vaccine. These vaccines were associated with various adverse side effects, including:. Because of these side effects, vaccines with a purified B.
Adverse reactions for these vaccines are less frequent than those for DTP, which is no longer available in the United States. The DTaP vaccine is given in five doses. Children should receive their first dose at 2 months old.
You should let your doctor know if your child has had:. Your doctor may decide to postpone vaccination until another visit or to give your child an alternative vaccine that contains only a diphtheria and tetanus component DT vaccine. Your child can still receive their DTaP vaccine if they have a mild illness, such as a cold.
However, if your child has a moderate or severe illness, immunization should be postponed until they have recovered. All these people want to meet your newborn—have they gotten the necessary vaccinations to protect your baby? Diapers, baby clothes, the crib. All of these are essentials on every expectant parent's checklist. What might be forgotten in the anticipation of a newborn is one of the most important items: vaccines for the parents, grandparents, and anyone else in the family who plans to spend time with the new bundle of joy.
To sort out which vaccines to get—and when—we talked to pediatrician Dr. Santhosh Nadipuram. Rubella is one of the most important for a mother who wishes to become pregnant, because congenital rubella infection can cause many problems with a growing baby.
I recommend two vaccines for pregnant parents: The first is the flu vaccine, and the second is pertussis whooping cough. The flu vaccine should be given to expecting parents as soon possible especially for mom, as the flu can cause worse complications during pregnancy. The antibodies generated by the flu shot will also circulate to the baby during pregnancy and protect the baby in early life.
The second vaccine is pertussis whooping cough , which comes with tetanus and diphtheria vaccines in a formulation called Tdap. This vaccine should be given in the 3rd trimester to a pregnant mother in order to protect mom and generate antibodies which will circulate to the growing baby. Whooping cough is a very dangerous infection for a young baby because children under the age of 3 months are most vulnerable to death from this illness.
As with the flu, when little babies become very sick with whooping cough, we have a limited number of treatments to get them better—and they can be invasive.
We have had outbreaks of pertussis here in California which resulted in many hospitalizations and infant deaths.
