Nov 9 (Reuters) - Canada’s main stock index hit a two-month high on Monday after drugmaker Pfizer said its experimental COVID-19 vaccine was more than 90% effective and as hopes of more stimulus under U.S. President-elect Joe Biden also boosted sentiment.

The companies said they have so far found no serious safety concerns and expect to seek U.S. authorization this month for emergency use of the vaccine.
