Traditional vaccines work by introducing a harmless piece of bacteria or virus into the human body to trigger an immune response, with most of these vaccines containing only a weakened or dead microbe.
The "T" of the TDaP and DTaP vaccines does not target the tetanus bacterium, therefore does not "introduc(e) a harmless piece of bacteria". It targets the toxin that the bacterium produces.
Further, while the "traditional" protein sub-unit type of vaccine uses a protein that is typically part of the target organism, the proteins in the vaccine are not necessarily produced from bacteria. For example, the Medicago protein sub-unit Covid vaccine, had it gone into production, would have used proteins produced using genetically modified plants, not SARS-CoV-2 viruses. One could say that this distinction between proteins refined from actual bacteria/viruses and proteins produced by other means is an abstruse quibble, but since Peter Navarro
(his graduate level degrees are in Public Administration and Economics, not anything medical ... I'm not surprised) claimed illusory precision by claiming Pfizer's vaccine
(He didn't call out Moderna, which also uses mRNA technology? Or was that writer Naveen Athrappully's careless omission?) is not a "true vaccine", the distinction illustrates that he was speaking outside of his understanding.
Viral vector vaccines, such as Johnson & Johnson's and the
not-authorized-in-the-US AstraZeneca Covid vaccines are fairly new, but Covid vaccines were not the first vaccines produced and approved using viral vector technology. Putting it bluntly, "Traditional vaccines" was a word game, and Navarro seems to be unaware that vaccine technologies have advanced since the 1950s (when dead/inactivated virus and protein sub-unit vaccine technologies were all that were). Since the 1950s, semiconductor technology has advanced from diffusion into germanium and silicon substrates to multiple layers "printed" onto substrates using photographic masks. Does that mean that the processor, chipset, and memory in you computer, tablet, and phone are not "
true semiconductors"?

The "reasoning" does not work, whether with semiconductors or vaccines.
