Vaccines against Viral Diseases Between the Past and the Modern Era
(Higher School for professors of Technological Education SKIKDA, 2024) Lakehal, ikram; دحدوح، فوزي
Vaccines are one of the most important forms of primary public health prevention. Nowadays, modern technologies provide many opportunities to prevent infectious diseases by vaccination. However, vaccines are still missing for a number of diseases like malaria, tuberculosis and AIDS, that are still major causes of morbidity and mortality. Therefore, the development of effective vaccines towards those diseases, as well as the improvement of efficacy and safety of existing vaccines, is needed. We use a large-n cross-country regression framework to evaluate the effect of social media and online foreign disinformation campaigns on vaccination rates and attitudes towards vaccine safety. We found that social media usage is highly predictive of the belief that vaccinations are unsafe; with such beliefs mounting as more organisation occurs on social media. In addition, there is a substantial relationship between foreign dis information campaigns and declining vaccination coverage over time.
