Will the monkeypox virus become more dangerous?
A few years ago, researchers scoured the remains of 1867 people who lived between 30,000 and 150 years ago for genetic traces of variola, the virus that causes smallpox. In the teeth and bones of four Northern Europeans from the Viking era, they found enough DNA to reconstruct entire variola genomes. The sequenced viruses weren’t direct ancestors of the feared variola strain that was eradicated in the second half of the 20th century. But they may hold a clue to how smallpox became so deadly. Over the span of 350 years, the Viking virus lost several genes , the researchers reported in a 2020 paper in Science...

Concern grows that human monkeypox outbreak will establish virus in animals outside Africa
Some content has been removed for formatting reasons. Please view the original article for the best reading experience. Eleven days after being bitten by one of her pet prairie dogs, a 3-year-old girl in Wisconsin on 24 May 2003 became the first person outside of Africa to be diagnosed with monkeypox. Two months later, her parents and 69 other people in the United States had suspected or confirmed cases of this disease, which is caused by a relative of the much deadlier smallpox virus. The monkeypox virus is endemic in parts of Africa, and rodents imported from Ghana had apparently infected captive prairie dogs, North...

The year's new drugs and biologics 2020
Drugs Today (Barc). 2021 Feb;57(2):101-177. doi: 10.1358/dot.2021.57.2.3275929.ABSTRACT2020 will go down in history as a year marked in every respect by the emergence and astonishingly rapid spread of the first major global viral pandemic in a century. It seems like nearly every event or story of the year was influenced in some way by COVID-19, and in that respect, the year ended on a high note with the authorization for emergency use of the first vaccines to prevent SARS-CoV-2 infection and drugs to treat COVID-19. Despite the pandemic's dominance of the 2020 headlines, productivity was at a record high level across all t...

Johnson & Johnson Announces European Commission Approval for Janssen ’s Preventive Ebola Vaccine
Discussions with the U.S. Food and Drug Administration (FDA) have taken place to define the required data set for filing US licensure. About Janssen’s Ebola Vaccine Regimen The Janssen preventive Ebola vaccine regimen, Ad26.ZEBOV and MVA-BN-Filo, utilizes a non-replicating viral vector strategy in which viruses – in this case adenovirus serotype 26 (Ad26) and Modified Vaccinia Virus Ankara (MVA) – are genetically modified so that they cannot replicate in human cells. In addition, these vectors carry the genetic code of several Ebola virus proteins in order to trigger an immune response.Janssen’s vaccine regimen ori...

Vaccines, Antibodies and Drug Libraries. The Possible COVID-19 Treatments Researchers Are Excited About
In early April, about four months after a new, highly infectious coronavirus was first identified in China, an international group of scientists reported encouraging results from a study of an experimental drug for treating the viral disease known as COVID-19. It was a small study, reported in the New England Journal of Medicine, but showed that remdesivir, an unapproved drug that was originally developed to fight Ebola, helped 68% of patients with severe breathing problems due to COVID-19 to improve; 60% of those who relied on a ventilator to breathe and took the drug were able to wean themselves off the machines after 18...

The Wuhan Coronavirus Is Spreading Fast. Will Doctors Be Able to Find a Treatment Before the Outbreak Ends?
Cases of a novel pneumonia-like illness that originated in Wuhan, China in December have now been confirmed in South Korea, Thailand, Japan, Taiwan, Macau—and, as of Jan. 21, the U.S. The virus’ geographic reach, as well as its newly discovered ability to spread via person-to-person contact, has health officials worried about the prospect of globals spread. As health officials scramble to learn more about the virus and is origins, researchers are simultaneously turning to the question of how to develop a vaccine or therapy that could help contain transmission worldwide—a feat that experts say is technical...
