COMM 3580: Health Campaigns: Public Health Campaigns on the Web
Check these out!
How to find examples using a contextual google search:
health campaign:vaping (or try your own keyword -no spaces after the colon though!)
campaign:homelessness
health promotion:vegetarian
public health:anxiety
If you find anything that looks good -take notes on the keywords/rhetoric that they use to describe themselves, the problem and proposed solutions -you will use these as keywords in the scholarly literature! :-)
