The study led by Dr. Otavio Ranzani provides the first real-world evidence that the tetravalent Qdenga vaccine protects against dengue and significantly reduces the risk of hospitalization during a major epidemic.
Results show that, 14 days after the first dose, the vaccine reduces symptomatic cases by up to 62% with the second dose and hospitalizations by 68%, reinforcing its value as an immediate tool in emergency health campaigns.
Although the work was conducted in Brazil, its findings are also relevant for Europe, where the spread of the Aedes mosquito increases the risk of local transmission, positioning Qdenga as a key tool in outbreak prevention and traveler protection.
A study evaluating how various shift work patterns contribute to kidney stone risk has revealed that shift workers have a 15% higher risk of developing kidney stones, especially younger workers and those with low levels of manual labor.

The findings of the novel study in Mayo Clinic Proceedings, published by Elsevier, indicate that kidney stone prevention efforts should extend to shift workers.
