There are no vampires in Atom Age Vampire (Seddok, l'erede di Satana, 1960), but there's a passing bit of red herring dialogue in which the mad scientist says something is "like an atom age vampire" though it's not at all like that.
An exotic dancer (Susanne Loret) doesn't want to stop stripping so her boyfriend (Sergio Fantoni) breaks up with her. She is soonafter hideously scarred in a car crash & refuses thereafter to see her boyfriend, who seems to have had a change of heart about whether or not he could stand to have his girl stripping for horny guys.
She is on the verge of suicide when a mysterious woman (Franca Parisi) offers to introduce her to a professor (which is to say, a mad scientist, played by Alberto Lupo) who has a new formula that causes scar tissue to regenerate.
The process regards an injected serum but the effects are temporary. The mad scientist, who soon falls in love with his patient, to sustain her beauty must use a back-up process that requires periodic murder of beautiful women & transplantation of god knows what since the script doesn't clearly reveal what, some gland apparently.
She does not reciprocate the mad professor's love, nor does she know he is killing women to keep her good looking. She only knows she's trapped with the doctor who has to keep renewing his mysterious process or she reverts to horribly scarred.
The mad professor has trouble killing women in his own persona, because it's wrong, so he injects himself with an ugly serum, which makes his face all scabby & brings out the Mister Hyde in him, though the premise seems to be only that ugly does as ugly is. After each kill, he exposes himself to radiation which counteracts the ugly-serum.
We're informed that the beauty-serum was derived from the ugly-serum & there might be unforseen side-effects as there were on animal models, so we keep waiting for the stripper to turn into the titular atomic vampire.
[SPOILER ALERT] The story gets increasingly ridiculous until the mad doctor is finally killed & his corpse reverts to not-ugly needing neither to be alive nor irradiated to turn back to normal.
Furthermore, it turns out the stripper didn't need further treatments after all & doesn't revert to scarred, despite what we were told previously. So she can be reunited with her old boyfriend & live happily ever after. Whether or not she's going to stop stripping we have no clue, but I'd guess she keeps at it since she looks good again & her boyfriend is no longer griping about it. [END SPOILER ALERT]
