'They've jumped the gun': scientists worry about Russia's Covid-19 vaccine

Rising chorus of concern over Sputnik V vaccine stems from opaque development and lack of mass testingCoronavirus – latest updatesSee all our coronavirus coverageIn 1977, Scott Halstead, a virologist at the University of Hawaii, was studying dengue fever when he noticed a now well-known but then unexpected feature of the disease.Animals that had already been exposed to one of the four closely related viruses that cause dengue and produced antibodies to it, far from being protected against other versions, became sicker when infected a second time, and it was the antibodies produced by the first infection that were responsible, allowing the second infection to hitchhike into the body.Continue reading...

In August 2020, during the coronavirus disease (COVID-19) pandemic, five locally acquired cases of dengue virus type 1 were detected in a family cluster in Vicenza Province, North-East Italy whereAedes albopictus mosquitoes are endemic. The primary case was an importation from West Sumatra, Indonesia. This is the first outbreak of autochthonous dengue reported in Italy. During the COVID-19 pandemic, screening of febrile travelers from endemic countries is crucial in areas where competent vectors are present.

In the last decades, a number of infectious viruses have emerged from wildlife or re-emerged, generating serious threats to the global health and to the economy worldwide. Ebola and Marburg hemorrhagic fevers, Lassa fever, Dengue fever, Yellow fever, West Nile fever, Zika, and Chikungunya vector-borne diseases, Swine flu, Severe acute respiratory syndrome (SARS), Middle East respiratory syndrome (MERS), and the recent Coronavirus disease 2019 (COVID-19) are examples of zoonoses that have spread throughout the globe with such a significant impact on public health that the scientific community has been called for a rapid int...

(CNN) — While coronavirus keeps spreading and killing with impunity, the world waits for a vaccine that could quash the pandemic. But details and timelines keep shifting. Here’s the latest on where we stand in the race for a vaccine: When will a Covid-19 vaccine be available to the public? No one’s sure yet, but the target is sometime in early 2021. Vaccines in development around the world are in various stages of testing. Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said he’s confident one of the vaccine candidates will be proven safe and effective by th...

Authors: Gorry C Abstract Meningitis, neuropathy, HIV, dengue-since the 1960s, Cuba has faced its share of epidemics. More recently, Cuban health pro-fessionals tackled domestic outbreaks of H1N1 (2009) and Zika (2016), and worked alongside colleagues from around the world to stem Ebola in West Africa; all three were categorized by WHO as public health emergencies of international concern. In December 2019, China reported its fi rst cluster of pneumo-nia cases, later identifi ed as the novel coronavirus disease COVID-19. In January 2020, Cuban authorities convened a multi-sector working group coordinated by the Min...

Researchers in Canada and China are testing a powerful immune booster that provides broad-spectrum protection against the common cold and a number of viruses including SARS, Ebola and H1N1. They’re currently running clinical trials to prove its effectiveness against coronavirus. I’m talking about quercetin – a powerful antioxidant that is already available as a supplement. Previous research shows that quercetin’s antiviral capacity works in three ways. Quercetin can: Stop the virus from infecting cells Reduce the reproduction of cells that are already infected And reduce infected cells resistance t...

By CHADI NABHAN, MD, MBA, FACP If you are a soccer fan, watching the FIFA World Cup is a ritual that you don’t ever violate. Brazilians, arguably more than any other fans in the world, live and breathe soccer—and they are always expected to be a legitimate contender to win it all. Their expectations are magnified when they are the host country, which was the case in 2014. Not only did the Germans destroy Brazilian World Cup dreams, but less than a year after a humiliating loss on their turf, Brazilians began dealing with another devastating blow: a viral epidemic. Zika left the country scrambling to understa...
