The CDC recommends that children receive their first dose at two months, the second dose at four months, the third dose at six months, the fourth dose between 15 and 18 months, and the fifth dose between 4–6 years. If the fourth dose of the DTaP immunization regimen falls on or subsequent to the recipients fourth birthday, the CDC states that only four doses are required to be fully vaccinated. In the instance that an individual under 18 has not received the DTaP vaccine, individuals should be vaccinated on the schedule in accordance with the vaccination "catch up schedule" provided by the CDC.Infants younger than 12 months of age, specifically less than three months of age, are at highest risk of acquiring pertussis. In U.S, there is no current tetanus-diphtheria-pertussis vaccination (whooping cough) recommended or licensed for new born infants. As a result, in their first few months of life, unprotected infants are at highest risk of life-threatening complications and infections from pertussis. Infants should not receive pertussis vaccination younger than six weeks of age. Ideally, Infants should receive DTaP (name of whooping cough vaccine for children from age 2 months through 6 years) at 2, 4, 6 months of age and they are not protected until the full series is completed.
Identity disorder in the DSM was first listed as a separate diagnosis in version III (1980). In the DSM-IV (1994), it was replaced by "Identity problem", which was not defined as a mental disorder per se, but was listed in a chapter containing problems that might be a focus of clinical attention. Identity disorder was downgraded to Identity problem as research indicated that distress over ones identity is so common that it might very well be considered part of the normality. In practice, if a persons distress persisted or worsened, an Identity problem would often be succeeded by a diagnosis of an actual disorder, such as a mood disorder or borderline personality disorder. In DSM-5 (2013), Identity problem was removed. See also
