DTaP is the childhood vaccine series. Only small children get it. It has a larger dose of the Diphtheria antigen (hence the capital D) and the Pertussis antigen (capital P). This provides a stronger immune stimulus to their developing immune systems, and has been proven to be both safe and effective for years.
Td is the booster to which you're referring. It is given every 10 years or if you have a traumatic incident where you come into contact with rusty metal or soil bacteria to protect you from the tetanus toxin. It, too, has been around for decades, widely given, and is both safe and effective.
Tdap is an adult combination vaccine. It contains the pertussis antigen at an adult dose, which is smaller than the childhood dose. It is recommended only 1 time per lifetime. One and done. We give it to pregnant women in order to have circulating antibodies around to transfer to their newborn via breast milk. The strategy is proven to save lives, and again, we've had these products for literally decades. We give it to pregnant women. It's safe and it works.
If you're curious as to why the d (small d, small dose) of diphtheria is still in the adult dose, the reason is that it amplifies the immune response, so you get better protection than from the tetanus antigen alone. There are a fair number of other vaccines that are conjugated to (attached chemically to) to diphtheroid antigen specifically for this purpose - to give a stronger immunity.
Now, you may be offered Tdap as a booster. Nothing wrong with that. Most clinics or pharmacies simply don't want duplicate inventory by stocking both the Tdap and the Td, so they stock Tdap as the single product for their adult patient. It saves money and does not compromise your safety.
Just because the COVID vaccines are garbage doesn't mean the old, proven-successfully vaccines are garbage too. We don't throw out the clinical experience we have of literally decades of giving these shots to millions around the world simply because Pfizer and Moderna lied to try and corner the market on mRNA tech.

There is iirc evidence that tetanus boosters are unnecessary and that fears and cases of lockjaw were highly overhyped
Also what of the MRNA reformulated time proven vaxes coming down the pipe?
"Oh its just a tetanus shot" but it's Pfizer new MRNA tetanus shot?
Wouldn't regular exposure to soil bacteria keep us "immunized" against Tetanus?
Fuck every single vaccine. Hopelessly naive if you still think any of them are "safe and effective".
But, they are.
Upvoted for the information. Do with it what we will, it's important to have this part of the story, regardless.
