A new study suggests that dengue may provide immunity against Covid-19

The not yet published study led by Miguel Nicolelis, a professor at Duke University, suggests the possibility that vaccines approved or under development for dengue may result in some form of protection against the new coronavirus.

The study points out that places where a large part of the population contracted dengue last year and earlier this year took longer to have exponential community transmission of Covid-19 and recorded fewer numbers of cases and deaths caused by the new coronavirus, indicating a possible immunological interaction between the two viruses.

To validate the observation made in Brazil, Nicolelis expanded the analysis of the correlation between dengue and Covid-19 to 15 other countries in Latin America, Africa and Asia, and the behaviour was repeated, according to him.

59 U.S. universities are backing the lawsuit filed by Harvard and MIT against the Trump administration trying to block a directive that would force international students to return to their home countries if all of their classes and coursework were taken remotely.

After Harvard and MIT filed their lawsuit on Wednesday in a federal court in Boston, dozens of other universities, including Duke and Standford and five other Ivy League colleges, submitted a so-call amicus brief.
