I spoke to the B.C. Centre for Disease Control to learn about the sophisticated, and global process of monitoring, cultivating and growing the influenza vaccination that begins almost a full year before the start of the November-April flu season.
To find out more information about the flu vaccine and how it protects you, head to the website
http://www.bccdc.ca/default.htm for lots of useful information.
If you have a science question you'd like answered, send Johanna Wagstaffe a tweet (@JWagstaffe) or an email at firstname.lastname@example.org.
