Immunization schedules and requirements
France
In France, DTP is mandatory and given at 2 months (1st dose) and 4 months (2nd dose) with a booster at 11 months. Subsequent boosters are recommended at ages 6, 11–13, 25, 45, 65, then every ten years. Netherlands
In the Netherlands, pertussis is known as kinkhoest and DKTP refers to the DTaP-IPV combination vaccine against diphtheria, kinkhoest, tetanus, and polio. DTP is given as part of the National Immunisation Programme. United Kingdom
In the United Kingdom, DTP is called the "3-in-1 teenage booster" and protects against tetanus, diphtheria and polio. It is given by the NHS to all teenagers aged 14 (the hexavalent vaccine is given to infants and provides the first stage of protection against diphtheria, tetanus, and polio, as well as pertussis, Haemophilus influenzae type B and Hepatitis B). Subsequent boosters are recommended for foreign travellers where more than 10 years has passed since their last booster. This is provided on the NHS free of charge due to the significant risk that an imported case of polio could pose to public health in Britain. United States
The standard immunization regimen for children within the United States is five doses of DTaP between the ages of two months and fifteen years. To be considered fully vaccinated, the Center for Disease Control and Prevention (CDC) typically requires five doses of Tdap.
In October 2011, in an effort to reduce the burden of pertussis in infants, the ACIP recommended that unvaccinated pregnant women receive a dose of Tdap. On 24 October 2012, the ACIP voted to recommend the use of Tdap during every pregnancy.The ACIP and Canadas National Advisory Committee on Immunization (NACI) recommended that both adolescents and adults receive Tdap in place of their next Td booster (recommended to be given every ten years). Tdap and Td can be used as prophylaxis for tetanus in wound management. People who will be in contact with young infants are encouraged to get Tdap even if it has been less than five years since Td or TT to reduce the risk of infants being exposed to pertussis. NACI suggests intervals shorter than five years can be used for catch-up programs and other instances where programmatic concerns make five-year intervals difficult.The World Health Organization (WHO) recommends a pentavalent vaccine, combining the DTP vaccine with vaccines against Haemophilus influenzae type B and hepatitis B. Evidence on how effective this pentavalent vaccine is compared to the individual vaccines has not yet been determined.A 2019 study in the American Economic Journal found that state requirements mandating the use of the Tdap vaccine "increased Tdap vaccine take-up and reduced pertussis (whooping cough) incidence by about 32 percent."

Excluding Pertussis
DT and Td vaccines, lack the pertussis component. The Td vaccine is administered to children over the age of seven as well as to adults.
