> traditional inactivated vaccines yield more robust and long-lasting protection

This is wrong. The formation of memory T/B cells has nothing to do with the vaccine tech. Both create lasting T/B cell memory immunity.

The problem is that it takes a week or so for T/B immunity to kick in - so you still get sick.

Thank you. Shouldn't have said that with such certainty. But maybe perhaps having just the spike protein vs the whole virus is eliciting a different response? Again, I don't know.

FYI, vector vaccines and mRNA vaccines also create t-cell immunity , not just antibodies. It’s not just “inactivated vaccines” that do so.

I did not know that. Thank you. Possibly in lesser quantities though? It is only related to the spike protein in the case of Covid. As I understand the natural immunity has a different fingerprint even with covid?

"natural" immunity would create antibodies and immunity that may be related to non-spike proteins of COVID-19 (I believe this depends on your own body's response and the severity of infection exactly what is generated).

The vector and mRNA vaccines only expose the spike protein (in various forms), so they don't generate immunity to other proteins of COVID-19.
