Why does mainstream information about the Covid vaccines focus only on ANTIBODIES?

Aren't antibodies only one part, of one part, of the immune system? What about all the other stuff like

NATURAL KILLER CELLS
KILLER T CELLS
GAMMA DELTA T CELLS

and any and all other parts of the immune system. Genuinely asking, I have no science education. Am I missing something or are they deliberately distorting their descriptions of the immune system to people through the media and governments? You hear and read
>antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies antibodies
all the time, but never anything about other cells/proteins.
