Tetanus, Diphtheria, Pertussis

Adacel (Tetanus, Diphtheria and Pertussis)

Adults, who have not previously received a dose of acellular pertussis vaccine, should receive combined Tdap vaccine rather than the diphtheria-tetanus (Td) booster dose. Adolescents and adults account for more than half of reported cases and the disease is often milder than in infants and children. Adults often require Tetanus and diphtheria booster prior to travel and a pre-travel consult is an excellent opportunity to get a Tdap vaccine.


Pertussis (whooping cough) is a highly contagious bacterial infection of the respiratory tract.  It is transmitted through inhalation of respiratory droplets or direct contact with respiratory secretions. There are between 20 to 40 million cases each year, with approximately 400 000 deaths worldwide. While most cases occur in infants and young children, adults are recommended to receive at least one dose of vaccine to not only prevent infection but also transmission to others, especially infants who are most susceptible to severe complication of the infection. 


Tetanus is an often fatal disease characterized by muscle rigidity and spasms, often in jaw and neck.  It occurs worldwide and can affect any age groups.  Transmission usually occurs through wounds contaminated with dirt, human/animal excreta or saliva;
