I am a PhD student doing an important research project about the confidence crisis in vaccinations which is the most controversial issue in the world in the last two years. I really understand the parents' fears about vaccinating their children especially in the era of COVID-19 pandemic as there is a lot of vague, wrong and unclear information about vaccinations. Unfortunately, that has been caused misunderstanding and serious concerns among parents in light of conflicting information from health authorities. I understand parents' concerns about filling out the survey too, I can guarantee that it is 100% completely anonymous and confidential. It has been verified and received the required ethical approvals from committees, The project meets the requirements of the National Health and Medical Research Council’s (NHMRC) Which has strict privacy rules, there is no single question that leads to revealing the identity of the participant. The survey does not attempt to change the participants' opinions or influence their attitudes at all, it is just trying to address biases and misunderstandings, it aims to find answers to the study’s questions. This is my PhD thesis, my study is not biassed towards any group, I'm trying to reach all groups, whether supportive, opponents or neutral, even doctors and medical Authitrities, since they are parents and have children as well, I believe that listening to all points of view will help in understanding the truth and addressing any concerns. I believe that expressing opinions honestly and transparently through scientific research will push officials and medical bodies to review what is related to vaccination because scientific research is the only way to discover facts and make the change.
