Delta strain rampant in Indonesia: Reuters reports on breakthrough cases of CoronaVac vaccine protection

Delta strain rampant in Indonesia: Reuters reports on breakthrough cases of CoronaVac vaccine protection

More than 350 doctors in Indonesia have contracted the coronavirus despite being vaccinated with CoronaVac from Sinovac Biotech, and “dozens” of them have been hospitalized. The reason is probably a more infectious and virulent delta strain (Δ, aka B.1.617.2, first discovered in India), writes Reuters, citing health authorities in the city of Kudus, Central Java […]

The risk of hospitalization from the Δ-strain of coronavirus is almost three times higher than from the “first” mutant

The risk of hospitalization from the Δ-strain of coronavirus is almost three times higher than from the “first” mutant

Coronavirus disease from the delta strain (formerly referred to in the media as “Indian”) leads to a significant increase in the risk of hospitalization. After checking cases with the disease from March 29 to May 20 and decrypting 38,805 samples of the virus genomes, this was the conclusion reached by British health care, according to […]

Just one mutation – and the bat coronavirus has learned to infect humans: a study

Just one mutation – and the bat coronavirus has learned to infect humans: a study

Just one mutation allows the RaTG13 virus, ineffective in infecting humans to a close relative of the SARS-CoV-2 coronavirus, successfully infecting human cells and intestinal organoids. This conclusion was made by German molecular biologists after the experiments; the preprint of their research is posted on bioRxiv.   The most likely hypothesis for the origin of […]

Scientists have checked the feces and mouths of bats in the south of the Russian Federation. Found “relatives” of SARS-CoV-2

Scientists have checked the feces and mouths of bats in the south of the Russian Federation. Found “relatives” of SARS-CoV-2

Potential pathogens similar to the pandemic coronavirus are circulating among bats in the southern Krasnodar Territory of Russia near Ukraine. This is the conclusion reached by the scientists of the Center. Hamaleas in the Russian Federation by checking the feces and swabs from the oral cavity of the large (R. ferrumequinum) and small (R. hipposideros) […]

Coronavirus. What should be the second generation vaccine: the development of American biologists

Coronavirus. What should be the second generation vaccine: the development of American biologists

To maximize protection against coronavirus, the next generation of vaccines should target not only the S-protein of viral particles, but also against the N-protein in which the genetic code of the pathogen is “packed”. The authors of two candidate vaccines write about this in the preprints of preclinical studies.   Microbiologists from two universities in […]

Israel clarifies the effectiveness of the Pfizer-BioNTech anti-coronavirus vaccine

Israel clarifies the effectiveness of the Pfizer-BioNTech anti-coronavirus vaccine

The vaccine from Pfizer-BioNTech a week or more after the second dose is 95.3% effective against coronavirus infection. Updated estimates of the effectiveness of a biological product in the fight against the COVID-19 epidemic in Israel were published by The Lancet.   The authors used surveillance data from the first four months of the national […]

The Coronavirus Disaster In India. Reason – “perfect Storm”, According To Who: Factors

The Coronavirus Disaster In India. Reason – “perfect Storm”, According To Who: Factors

The spike in the incidence of COVID-19 that hit India’s health system this spring was driven by a combination of factors, not just the spread of a more infectious and less immunocompromised strain. This was stated by the representative of the World Health Organization Tarik Yasharevich, writes Reuters.   One of the main causes of […]

J&j Vaccine Protects All Trial Participants From Hospitalization And Death In COVID-19

J&j Vaccine Protects All Trial Participants From Hospitalization And Death In COVID-19

Johnson & Johnson’s single-dose vaccine fully protects against hospitalization and death with COVID-19 approximately one month after administration. This is also true for countries where mutant variants of the coronavirus are common. J&J Chief Scientist Paul Stoffels said this, commenting on the publication of primary data from phase III clinical trials in the New England […]

If You Have Had A Coronavirus Disease Caused By A Non-brazilian Strain

If You Have Had A Coronavirus Disease Caused By A Non-brazilian Strain

If you have had a coronavirus disease caused by a non-Brazilian strain of SARS-CoV-2, then the effectiveness of your protection against re-infection with this mutant is from 54% to 79%. This conclusion was reached by an international group of scientists, their research was published by the journal Science.   Despite the fact that in Manaus, […]

Effectiveness of Moderna and Pfizer-BNT Against Symptoms and Hospitalization: First Estimates from the USA

Effectiveness of Moderna and Pfizer-BNT Against Symptoms and Hospitalization: First Estimates from the USA

American doctors have assessed the effectiveness of Moderna and Pfizer-BNT RNA vaccinations in preventing COVID-19 symptoms no longer in clinical trials, but in real conditions of mass vaccination of the US population. A preprint (not yet peer reviewed report) is available on medRxiv. The report was compiled by experts from the Mayo Clinic network using […]
