I'll talk a bit about that and then I'll turn to Deputy Minister Lucas, who is in charge of the Health Canada regulatory team.
Early on, we knew there would be the need for speed to approve a whole host of medical supplies, including vaccines and therapeutics, and obviously devices, testing, components, etc. We were able to accelerate the capacity of the regulatory body in a few different ways. One was by ensuring they had the financial and human resources to be able to greatly increase their capacity to review applications. We added people and added capacity. As Deputy Minister Lucas will tell you, in terms of vaccine approvals, there are people working literally 24 hours a day, seven days a week on teams assigned to vaccines, so that they can do a very thorough review of the data and understand it as quickly as possible.
I will also say the rolling regulatory approval for vaccines is very important. Typically, from what I've learned in this portfolio, vaccine development can take up to 10 years from the concept to the actual approval because, of course, of the need for submissions of data after every stage of the development, including a number of clinical trials, to test whether it's effective and safe. A rolling approval allows for vaccine manufacturers in this case to be able to submit data very quickly, as they acquire it, so we're not having to review mountains of data at the regulatory approval stage. Rather, we are able to review the data at each stage, as it comes in.
That allows for a very rapid back and forth as well between the manufacturers and Health Canada if there's missing data, for example, if they need clarity, if they need data to be resubmitted or if there are gaps in the data. Rather than the manufacturer having a significant lag time, in some cases, in being able to get that, they can respond very quickly.
I will turn, with your permission, to Deputy Minister Lucas for a few more words on the process.
