Tdap vaccine

I did finally get a Tdap vaccine shot on Wednesday.


Diphtheria, Tetanus, and Whooping Cough Vaccination: What Everyone Should Know

- DT (generic) and Td (Tenivac® and generic) provide protection against diphtheria and tetanus.
- DTaP (Daptacel®, Infanrix®, Kinrix®, Pediarix®, Pentacel®, Quadracel®, and Vaxelis™) provides protection against diphtheria, tetanus, and whooping cough.
- Tdap (Adacel® and Boostrix®) provides protection against tetanus, diphtheria, and whooping cough.

Upper-case letters in these abbreviations mean the vaccine has full-strength doses of that part of the vaccine. The lower-case “d” and “p” in Td and Tdap means these vaccines use smaller doses of diphtheria and whooping cough. The “a” in DTaP and Tdap stands for “acellular,” meaning that the whooping cough component contains only parts of the bacteria instead of the whole bacteria.

Studies estimate that diphtheria toxoid-containing vaccines protect nearly all people (95 in 100) 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.
..
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.

In studies showing how well the whooping cough component works, Tdap fully protects:
- About 7 in 10 people in the first year after getting it.
- About 3 or 4 in 10 people four years after getting it.
