Drug may give ‘immunity’ to nicotine

AMERICAN doctors are testing a radical new way to help smokers quit — an injection that “immunises” them against the nicotine rush that fuels their addiction.

That pleasurable buzz has seduced 75-year-old Mario Musachia into burning through nearly half a million cigarettes in half a century.

Now he is among 300 people testing an experimental vaccine that makes the immune system attack nicotine in much the same way it would fight a life-threatening germ.
