WHITEHORSE, Yukon - The wealthy Canadian couple who snuck into a remote Yukon community to receive COVID-19 vaccinations intended for vulnerable First Nations residents were fined $1,150 each and won’t get any jail time.
Former casino mogul Rodney Baker, 55, and his wife Ekaterina Baker, a 32-year-old actor, flew into Whitehorse in January, where they chartered a private plane to take them 450 kilometres northwest to Beaver Creek, a community of approximately 100 people, most of whom belong to White River First Nation. In January, vaccines were scarce in Canada, and were prioritized for health care workers and some vulnerable communities, such as First Nations.
https://www.vice.com...n-covid-vaccine RUDN University mathematicians built a model of COVID-19 spreading based on two regression models. The mathematicians divided the countries into three groups, depending on the spreading rate and on the climatic conditions, and found a suitable mathematical approximation for each of them. Based on the model, the mathematicians predicted the subsequent waves. The forecast was accurate in countries where mass vaccination was not introduced. The results are published in Mathematics.

Mathematicians have identified three groups of countries. The first category includes countries where the first wave of the pandemic lasted about 180 days. These are the countries with the lowest spreading rate, with an average annual temperature of 15-38° (for example, Saudi Arabia, Egypt). In the second group of countries (for example, the United Kingdom, Germany, Italy) with an average annual temperature of 2-31°C, the first wave lasted 90 days. Countries in this group are characterized by an average infection rate and stopping periods with low virus spreading rate. The third group includes countries with the highest spreading rate and no stopping periods, with an average annual temperature of 2-18 degrees Celsius—for example, the United States and Russia.
For modeling, scientists used WHO data on the number of cases from March 1 to November 15, 2020. RUDN mathematicians chose the most suitable regression models—methods for statistical research of the influence of several variables on one value. The Fourier series and the sum of the sine-waves were the most accurate for the modeling COVID-19 cases. This means that the curve of new cases of the disease is represented either as a sum of Fourier functions (they can be represented as waves of a certain frequency and amplitude), or as a sum of ordinary sine-waves.
As a result, professor Ragusa obtained the calculated values of the peak of the second or third wave in the studied countries. Different models gave close forecasts with a difference of several days. The obtained predictions were compared with the data available at that time. It turned out that the model provides fairly accurate predictions if the country does not introduce wide vaccination. For example, the calculated value of the peak of new cases in Egypt is 1481 people on January 11, 2021; the real peak occurred on December 31 with 1418 cases. In other countries, the model provides an accurate prediction until the beginning of 2021. After that, the vaccination effect takes place and the calculated values differ from the reality. For example, for Germany, the predicted and real values are close until about January 15, 2021, and on February 15 they differ by about 2.5 times.

Microorganisms, could help explain symptoms some men with COVID-19 have reported and have important implications for men's health.
https://medicalxpres...cov-infect.html Researchers of a recent study looking at whether the authorized COVID-19 vaccines harm male fertility were deluged with hundreds of emails from freaked-out men and their worried partners leading up to publication. Now, the findings from 45 vaccinated men are in: none showed any significant signs of lower sperm counts after getting their shots.
It's still possible that men who experience post-vaccination side effects may suffer from lower sperm counts for a few weeks, just as they might after a viral infection. But there's no reason to worry about significant adverse impacts on male fertility, said study co-author Ranjith Ramasamy, MD, of the University of Miami Health System, in an interview with MedPage Today. "People should not be concerned. The vaccines are very safe."

https://sputniknews....-global-leader/ A Russian military research unit that was involved in the development of Sputnik V is working on a new coronavirus vaccine in the form of chewing gum, the RBC news website reported Friday.
The Defense Ministry’s 48th Central Research Institute collaborated with the state-run Gamaleya Research Institute in Moscow to develop and trial Sputnik V last year. Russia, facing accusations of rushing human trials, touted the adenoviral vector vaccine as the world’s first to be approved for widespread use.
Citing an unnamed Defense Ministry source and confirmation from the 48th Central Research Institute’s director, RBC said “work is underway” toward developing a mucosal Covid-19 vaccine in the form of chewable tablets and pastilles.
“After testing, the drug will be included in various treatment and prevention regimens for coronavirus,” the source was quoted as saying.
Col. Sergei Borisevich, who heads the 48th Central Research Institute, confirmed work on the new vaccine but did not specify what stage it was at.

More scientific evidence in countries such as the US and France has emerged to suggest that those countries may have had COVID-19 cases way before they officially confirmed.
A US government study suggested that the coronavirus may have already been circulating among people one month earlier than it was officially confirmed, and French scientists also presented scientific evidence that the country's cases were caused by an indigenous virus strain prevailing before 2020.
Chinese scientists urged that such evidence should not go unnoticed, and should serve as evidence that the next-stage virus-tracing investigations should be focused on countries which reported cases earlier than they previously identified, especially the US.
A study of more than 24,000 samples taken for a National Institutes of Health (NIH) research program in the US between January 2 and March 18, 2020 suggested that seven people in five states - Illinois, Massachusetts, Mississippi, Pennsylvania and Wisconsin - may have been infected well before the country's first confirmed cases that were reported in January 21, 2020.
The results suggest that the virus may have been circulating in Illinois, for example, as early as in December 24, 2019, one month earlier than the US authorities confirmed.
The data suggests the virus was in the five states far away from the initial hot spots and areas that were considered its points of entry into the country, the study said.
Zeng Guang, chief epidemiologist of the Chinese Center for Disease Control and Prevention, told Global Times on Wednesday that the US should be prioritized in the next-stage investigation, as the country was slow to test people at an early stage, and it possesses so many biological laboratories all around the world. "All bio-weapons related subjects that the country has should be subject to scrutiny," Zeng said.
Ju Liya, chief scientist of the European precision medicine platform in France, also told the media last week that after having studied the genetic sequence of the viruses from earlier patients, they found the outbreak in France was caused by an indigenous virus, which was prevailing in the country even before 2020.
She also claimed that the France outbreak had no link with the Chinese city of Wuhan, where the first coronavirus case was reported, as the hereditary feature of the virus strain detected in France is very different from that found in COVID-19 patients in China.
In response to a question about the US study, Zhao Lijian, spokesperson of China's Ministry of Foreign Affairs, said at a Wednesday briefing that scientific journals and scientists around the world have pointed out similar evidence, including chief Swedish epidemiologists who believe that there were cases of coronavirus in Sweden as far back as November.
"It is obvious that the outbreak had multiple origins," said Zhao.
