“Measles Vaccine issue”

 preparing my proposal doc, My phd thesis in communication studies, specifically in health communication. I will investigate the role of mediated communication such as Twitter or Facebook in public health issues. I will focus on immunizations. Anti-vaccination groups make some campaigns and post many messages and posts about the risk of vaccines through social media, while the health authorities attempt to fight these movements and educate people about the importance of vaccination. I will examine the impact of public health messages of childhood vaccination on parental attitudes toward vaccinating their child. The mediated communications which address a common health concern among parents will be the focus, and I will apply my study to two different countries: Saudi Arabia and Australia.

My Question that I need your help with is: Do you think its better to do that through using Quantitative or Qualitative method by choosing a case study such as “Measles Vaccine issue” as a case study in both KSA & AUS, and use two 2 tools to collect our data (questionnaire+interview) Or (content analysis+text analysis) or (questionnaire+content analysis) that’ may help to manage the research later, rather than using mixed method that needs to build questionnaires and survey for both country, which needs harder effort?
