Tetyana Obukhanych has far from a "nuanced" view; she is anti-vax through and through. And she has had her entire anti-vaccine book debunked by numerous other medical professionals (on the merit of its claims, which can on occasion, as in this case, be just as false or misleading coming from an immunologist as from some guy on Reddit). She is not the only trained medical professional to adopt a crank ideology, pushing half truths and misleading the public with cherry-picked information, though she is one of the few anti-vax immunologists I've heard of.
The "too much in one go" argument holds little or no merit. Newborns are exposed to more live pathogens shortly after birth than can be found (live or dead) in the entire vaccine schedule through their teen years.
Meanwhile, some of the same proponents of a "revised" vaccine schedule -- as well as devout non-vaxxers -- purport the supremacy of "natural immunity": contracting chicken pox is somehow healthier than getting a shot. So having a full-blown varicella infection is less taxing on children than receiving an injection of weakened virus? A preventive modality which typically confers immunity for 10 to 20 years while resulting in little or no symptoms is less "taxing" on the immune system than a fully symptomatic infection?
Tetanus is one of those very serious, but slowly-progressing infections, like rabies, against which a vaccine is highly effective after the actual disease exposure. Can't argue with you there, as long as a person who's been exposed receives prompt medical attention. Didn't get the tetanus vaccine as a child? Okay, whatever. Don't go for a booster after you step on a nail in your grandma's attic? Good luck.
