What type of immunity is pertussis?
Cell-mediated Immunity. Although the overwhelming focus of most studies on defining correlates of immunity to B. pertussis have focused on serum antibody responses, there is growing evidence that cellular immunity is required for effective clearance of a primary infection with B.

Do you need Tdap every 10 years?
Studies estimate that tetanus toxoid-containing vaccines protect essentially all people 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.
Can you have pertussis more than once?
Can you get pertussis more than once? Reinfection appears to be uncommon but does occur. With natural infection, immunity to pertussis will likely wane as soon as seven years following disease; reinfec- tion may present as a persistent cough, rather than typical pertussis.
How often should I get pertussis vaccine?
