The vaccines confer an antibody response, which isn't all that important in terms of combating disease: "Antibodies that offer protection'? Let’s pause right here. When was it ever proven that antibodies offer protection? In fact, the opposite has been observed. Don’t we remember another prominent scientist (and a Nobel Prize winner in 1960) Sir Frank Macfarlane Burnet telling us the following regarding the role of antibodies (or rather lack thereof) for immunity in children who lacked antibody production due to a genetic condition called agammaglobulinemia:

“To everyone’s surprise [children with agammaglobulinemia] showed a normal measles course with a typical rash which faded at the normal time and was followed by just as substantial immunity against reinfection as would be shown by any other convalescent. Antibody production is therefore not necessary either for recovery from or for the development of immunity to measles.” (Burnet and White. Natural History of Infectious Disease. Cambridge University Press, 1940) "

FDA could have used T-cell expression as a standard of efficacy but chose not to despite knowing antibodies were being over sold as hallmarks of immunity.
