MADRID, Sept 28 (Reuters) – Using vaccines to fight cancer
is a field littered with failures but experts believe it is

Keytruda, the first in a new wave of immune-boosting medicines

MADRID, Sept 27 (Reuters) – Early results for a closely

boosts the immune system suggest the cocktail is promising,
though limited patient numbers mean the data is far from
The British drugmaker, which fended off a $118 billion
takeover bid from Pfizer in May in part by talking up
its cancer drug prospects, has high hopes for the combination of
two experimental drugs known as MEDI4736 and tremelimumab.
