Vaccine. 2023 Dec 7;41(50):7498-7502. doi: 10.1016/j.vaccine.2023.11.019. Epub 2023 Nov 15.


Purpose: Access to internet-based resources may help to improve population health awareness and literacy surrounding immunization related topics. The primary aim of this study was to evaluate and analyze trends for a single immunization resource website, the Melbourne Vaccine Education Centre (MVEC).

Principal results: Over a four-year period from 2019 to 2022, the website had over 2 million visitors from 236 countries. Users were predominantly female, in the 25 to 44 year age bracket and accessed resources using a mobile device. There was significant interest in specific vaccine related topics, particularly during the COVID-19 pandemic, that corresponded with key vaccine related recommendations and updates from a national level. Usage patterns saw spikes in interest around topics including COVID-19 vaccine administration techniques and adverse events following immunization.

Major conclusions: Use of online platforms including websites such as MVEC may reflect trends and behaviors towards immunization related information. Analysis of usage patterns have provided user insights into key domains of interest including areas such as vaccine administration, policies and programs, vaccine safety and barriers to vaccine uptake.
