Cameroon marriage. Need I a visa or vaccination from Canada?

Hi. I'm getting married to a man from Cameroon in Cameroon in October.  Do I need a visa to enter that country? If so, where do I get one and how long does it take? Also do I need any vaccinations to travel there?
Any assistance you can provide is very much appreciated. 
Thank you

Hello

Yes, you need a visa.

Yellow fever vaccination needed as well.
