Professor Nicolelis found that in regions that have had outbreaks of Dengue fever this year or last, the incidence of coronavirus is low and growing more slowly than in the rest.
According to Nicolelis, if his guessconfirmed, people will be able to obtain a certain level of immunity to COVID-19 thanks to the dengue vaccine. The professor added that, according to previous studies, people with antibodies to Dengue gave false positive test results for antibodies to coronavirus, even if they never got sick.
Scientists have discovered a connection between the pastDengue fever and coronavirus outbreaks in several regions of Brazil, other parts of Latin America, Asia and the Pacific and Indian Oceans.
