how long is tetanus good for
FACT: People with tetanus may have to spend several weeks in the hospital under intensive care and frequently need to be on a ventilator. FACT: For adults, a tetanus-diphtheria booster (Td) every 10 years gives protection against both tetanus and diphtheria. A tetanus-diphtheria-acellular pertussis (Tdap) vaccine should be given to adults in place of one Td vaccine to protect them against pertussis (whooping cough), too.
Titers lasted a similarly long time in that studyâa half-life of 19 years for diphtheria antibodies and a half-life of 11 years for tetanus antibodies. Evidence from other countries also suggests adding time between boosters appears safe.
