Effectiveness Decrease in<unk>  deaths by age group between 1990 and 2017 Following vaccination, 95% of people are protected from diphtheria, 80% to 85% from pertussis, and 100% from<unk> . Globally deaths from<unk>  in newborns decreased from 787,000 in 1988 to 58,000 in 2010, and 34,000 deaths in 2015 (a 96% decrease from 1988). In the 1940s, before the vaccine, there were about 550 cases of<unk>  per year in the United States, which has decreased to about 30 cases per year in the 2000s. Nearly all cases are among those who have never received a vaccine, or adults who have not stayed up to date on their 10-year booster shots. Pregnancy Guidelines on prenatal care in the United States specify that women should receive a dose of the Tdap vaccine during each pregnancy, preferably between weeks 27 and 36, to allow antibody transfer to the fetus. All postpartum women who have not previously received the Tdap vaccine are recommended to get it prior to discharge after delivery. It is recommended for pregnant women who have never received the<unk>  (i.e., neither DTP or DTaP, nor DT as a child or Td or TT as an adult) to receive a series of three Td vaccinations starting during pregnancy to ensure protection against maternal and neonatal<unk> . In such cases, Tdap is recommended to be substituted for one dose of Td, again preferably between 27 and 36 weeks of gestation, and then the series completed with Td. Specific types The first vaccine is given in infancy. The baby is injected with the DTaP vaccine, which is three inactive toxins in one injection. DTaP protects against diphtheria, pertussis, and<unk> . This vaccine is safer than the previously used DTP. Another option is DT, which is a combination of diphtheria and<unk> s. This is given as an alternative to infants who have conflicts with the DTaP vaccine. Quadrivalent, pentavalent, and hexavalent formulations contain DTaP with one or more of the additional vaccines: inactivated polio virus vaccine (IPV), Haemophilus influenzae type b conjugate, Hepatitis B, with the availability varying in different countries. For the every ten-year booster Td or Tdap may be used, though Tdap is more expensive. Schedule Because DTaP and DT are administered to children less than a year old, the recommended location for injection is the anterolateral thigh muscle. However, these vaccines can be injected into the deltoid muscle if necessary. The World Health Organization (WHO) recommends six doses in childhood starting at six weeks of age. Four doses of DTaP are to be given in early childhood. The first dose should be around two months of age, the second at four months, the third at six, and the fourth from fifteen to eighteen months of age. There is a recommended fifth dose to be administered to four- to six-year-olds. Td and Tdap are for older children, adolescents, and adults and can be injected into the deltoid muscle. These are boosters and are recommended every ten years. It is safe to have shorter intervals between a single dose of Tdap and a dose of the Td booster. Additional doses Booster shots are important because lymphocyte production (antibodies) is not at a constant high rate of activity. This is because after the introduction of the vaccine when lymphocyte production is high, the production activity of white blood cells will start to decline. The decline in activity of the T-helper cells means that there must be a booster to help keep the white blood cells active. Td and Tdap are the booster shots given every ten years to maintain immunity for adults nineteen years of age to sixty-five years of age. Tdap is given as a one-time, first-time-only dose that includes the<unk> , diphtheria, and acellular pertussis vaccinations. This should not be administered to those who are under the age of eleven or over the age of sixty-five. Td is the booster shot given to people over the age of seven and includes the<unk>  and diphtheria toxoids. However, Td has less of the diphtheria toxoid, which is why the "d" is lowercase and the "T" is capitalized. In 2020, the US Centers for Disease Control and Prevention (CDC) Advisory Committee on Immunization Practices (ACIP) recommended that either<unk>  and diphtheria toxoids (Td) vaccine or Tdap to be used for the decennial Td booster,<unk>  prevention during wound management, and for additional required doses in the catch-up immunization schedule if a person has received at least one Tdap dose.
