Vaccine Trials on the Rise

Vaccines are one of the most useful and cost-effective disease preventive methods available, helping to improve long-term health and eradicate disease across the globe. There has been an upsurge in the number of vaccination clinical trials undertaken in resource-constrained nations over the last decade. Vaccine studies for diseases like malaria and dengue fever, which are endemic in many low- and lower-middle-income countries, are among them. Majority of these vaccine trials are being conducted in Asia and Africa as the burden of infectious diseases are high in these continents.
