Rollout of COVID-19 vaccines has begun. But getting the jab doesn't mean abandoning masks, distancing and handwashing. Here's why the current preventive measures must continue post-vaccine.
The best approach for protecting everyone’s health will require us to provide different vaccines to different people according to need and availability.
We should applaud drug companies for developing COVID-19 vaccines in record time, but let’s not be under any illusion about the profits that are motivating them.
Vaccine hesitancy is not new, but it has a new element: few people can remember the devastating impact of diseases such as smallpox and polio and it is hard to see the lives saved by vaccination.
Because Pfizer-BioNTech and Moderna vaccines have been developed in record time, many wonder whether companies cut corners or compromised safety.
Two pharma companies have announced early COVID-19 vaccine trial results with over 90 per cent effectiveness. What does that mean for getting back to normal?
Canada has set aside a total of 414 million doses of different types of vaccine. Some exploit known mechanisms, others are based on previously untested approaches.

Results from phase 1 trials of a COVID-19 mRNA vaccine created a burst of optimism. But details the company failed to release suggest it is too early to speculate whether the vaccine is effective.
