kvs, do you consider Phase 3 trials to be unnecessary? It is my impression that in the field of life saving drugs (i.e. cancer treatments) they just prolong the time for a drug to enter the market by 5 years.

It is a catch 22 situation... there are lots of drugs that are developed that seem safe and effective. Thalidomide was a very good drug that did exactly what it was supposed to do... the problem was that it was used to treat depression and did some terrible things to the unborn children of women if they were pregnant when they took that drug. This was a problem because not every woman knows whether they are pregnant when they start taking that drug.

If you made a rule that thalidomide could only be prescribed for men it would be fine.

The reverse is true too however where drugs that could save many lives are held up because they need to be thoroughly tested to make sure they work and have no dangerous side effects and lots of people can die because the companies are afraid of being sued and are just covering their asses.

I would think the best solution is emergency use... someone who is going to die if they don't get the drug tested or not should be allowed to join the testing and see if it can save them... sign a waver so they can't sue if it makes them infertile or gay or something... I think if I were dying I would be happy to try it and sign anything you like.

The Sputnik V vaccine showed very good early results and has been peer reviewed and made from solid reliable methods that have worked well in the past so after two trials they registered it as an option for those who want to take the risk can try it.

In this case with a world wide pandemic providing enough samples becomes the problem so access is the real issue here.

But I am sure politics will be involved as well...

Svetlana Zavidova rears her ugly head again in the article - still shilling for the Western pharmaceutical company dollars.

NPO "Crystal" produces air recirculators for large premises


NPO Kristall (Leningrad Region, Tosnensky District, town of Fedorovskoye) produces air recirculators with ultraviolet lamps for large rooms. The principle of operation of recirculators is based on the ability of ultraviolet radiation to destroy viruses, bacteria and fungal spores.

Recirculators allow solving the problem of air disinfection in large rooms that are not equipped with disinfectants in ventilation circuits. NPO Kristall manufactures air recirculators for premises with a volume of up to 5000 m³ per apparatus, which can be used in trade premises, public catering, product warehouses, train stations, airports , etc.


"ODV-RB" is the name of a series of recirculators of the NPO Kristall company for air disinfection. The recirculators have a Registration Certificate from Roszdravnadzor.

The process of air disinfection with UV radiation is referred to as "disinfection". Disinfection is a technological process that reduces the number of bacteria in the air, including pathogens, as well as viruses, protozoa and spores.

The letter of Rospotrebnadzor dated 10.03.2020 No. 02 / 3853-2020-27 "On measures to prevent a new coronavirus infection (COVID-19)" sets out recommendations for heads of organizations, regardless of organizational and legal forms and forms of ownership, for the use of germicidal lamps in workrooms , air recirculators for regular air disinfection.

Bactericidal and antiviral effects of ultraviolet radiation

Ultraviolet rays are part of the electromagnetic radiation spectrum and cover the region with wavelengths from 100 to 400 nm. The division of biologically active ultraviolet radiation into three areas is accepted:

UV-A with a wavelength of 400-315 nm;
UV-B with a wavelength of 315-280 nm;
UV-C with a wavelength of 280-200 nm. The rays of the third area have the ability to kill various viruses, bacteria and fungal spores (the so-called bactericidal effect). This effect is intensely expressed in ultraviolet rays with wavelengths of 265-200 nm.


Conditions for efficient operation of the recirculator

Multiplicity. The efficient operation of a recirculator is related to the volume of the room in which it operates. The productivity of one or several recirculators in one room should be 4-6 times higher than the volume of the treated room. Then he will be able to pass the entire volume of air in the room through himself every 10-15 minutes. This is very important, since people in the room serve as potential sources, and it is necessary that the air after exhalation undergoes disinfection as soon as possible. For example, for a room with an area of ​​36 m² with three-meter ceilings, it is necessary to use a recirculator or recirculators with a total capacity of about 500 m³ / hour.

The hourly capacity (m³ / hour) of a recirculator or a group of recirculators should be 4-5 times the volume of the room in which they will be used.

NP "NASCI" (National Association of Specialists in the Control of Infections Associated with the Provision of Medical Care) in its Temporary Guidelines "Prevention of the importation and spread of COVID-19 in medical organizations" dated May 14, 2020 recommends the use of various kinds of air purifiers - recirculators, if possible ensuring the air exchange rate of at least 4.

For example, we have a room with a volume of 100 m³. This room has supply and exhaust ventilation with an air exchange rate equal to 2. The ventilation works constantly and supplies clean outdoor air. A person sick with influenza enters this room at time 0. It is known to emit 10,000 viruses / hour during breathing and talking. An hour later, the patient leaves the room. For example, if a recirculator is installed in the room, then it is constantly in operation.

Virologists consider the infectious dose, for example, for influenza, equal to 20, that is, if a healthy person absorbs 20 viruses in a reasonable time (in the region of 1 hour), then with a 50% probability he will get the flu. Depending on the conditions (the presence of ventilation and a recirculator with different capacities), a certain distribution of viruses will be installed in this room.

The first case - there are no recirculators in the room. Then the concentration of viruses will be established in it, equal to 50 pcs./m³, and even if after 1 hour a sick person leaves the room, a sufficiently high contamination of the air will persist for a long time (more than an hour) and healthy people in the room for a short time (about 20 minutes ) will receive an infectious dose, i.e., with a 50% probability of getting sick.
The second - a recirculator with a capacity of 100 m³ / hour is installed in the room. As can be seen from the figure, in this case, a sufficiently high concentration of microorganisms will be established in the room (33 pcs / m³), ​​which practically preserves the likelihood of illness of healthy people in the room, even after the patient leaves the room.
The third - a recirculator with a capacity of 500 m³ / hour is installed in the room. The concentration of microorganisms in the room will be only 14 pcs./m³, which drops very quickly when the patient leaves the room, and thus the disease of healthy people in the room is prevented.
Fourth, a recirculator with a high performance is installed in the room, for example, 1000 m³ / h, so that the air exchange rate becomes 10. As a result, by the same time, the concentration of microorganisms will not exceed a very low level of 8 pcs / m³, which will rapidly decrease from the moment the patient leaves the room. Therefore, such air exchange rates are used for very clean rooms.


It can be seen from the graphs that only the use of a recirculator with a high performance (the air exchange rate is more than 4) allows a guaranteed concentration reduction below the infectious dose.

The recirculator will be effective, that is, eliminate the risk of disease, if its capacity is at least 4-5 times the volume of air in the room. The use of recirculators, the total capacity of which (m³ / hour) is equal to or even less than the volume of the room to be disinfected, does not have any actual effect.

Dose. Ultraviolet radiation dose. To disinfect each type of microorganism (for example, by 99.99%), a certain UV dose is required. The UV dose is the product of the exposure time and the exposure intensity.

At a given UV power and a given speed of air movement through the recirculator (capacity), the larger the volume of the irradiation chamber in the recirculator, the more air is exposed to ultraviolet radiation, the more air the recirculator can handle.

The higher the radiation intensity, the higher the UV dose received per unit volume of air. The intensity can be increased by increasing the number and power of radiation sources, and it can also be increased by using special coatings for the walls of the chamber with lamps, these coatings will reflect ultraviolet light, thereby reducing the loss of ultraviolet radiation and increasing its intensity.

Various materials are used to cover the inner walls of the recirculator, which reflect ultraviolet light. The higher the reflectance, the more times UV radiation will be reflected from the walls and irradiate the treated air. For example, polished steel, which has a reflectance of about 40%, will reflect the UV beam 6 times. Aluminum with a reflectivity of 80-85% - 21 times. In modern UV recirculators, materials with a reflectance of more than 95-98% are used, which makes it possible to increase the intensity in the irradiation chamber.

When designing technically advanced recirculators, they strive to ensure the maximum internal volume of the housing and the maximum reflectivity of its walls. It follows from this that an efficient recirculator with a large air flow rate and intended, for example, for sales areas cannot be small in size.

Recirculator operation description

The device consists of a metal case, which contains a recirculation motor, a fan and UV lamps.

The fan sucks air into the unit, where the air is disinfected with ultraviolet light and the already purified air is thrown out. The construction is closed and ultraviolet rays do not reach people in the room. No ozone is generated during operation.

Recirculator applications:

Shopping centers and shops
Medical industry and institutions;
Pharmaceutical enterprise;
Schools, kindergartens and other educational organizations
Medical and sports facilities
Public catering and trade enterprises;
Food industry enterprises;
Agro-industrial enterprises
Food and processing industry enterprises

Even CNN can't help but admit it now.

Even if they like the look of it they have to go through all their own tests and checks which takes time.

Apparently the Sputnik Vaccine is easy to make so many are looking to sign deals to make it themselves to boost the numbers of vaccines they can roll out.

The early positive news seems to be continuing with results suggesting it is efficient in all age groups which is rather important. It is cheap and easy and simple to store and transport. It is kept at between 2 and 8 degrees C, which is not demanding conditions by any means.

Most importantly the Russians are not using it as a political weapon to be used against other countries like the EU and US already are.

Ministry of Health of Nicaragua has authorized the use of Sputnik V

Moscow, February 3, 2021 – The Russian Direct Investment Fund (RDIF, Russia’s sovereign wealth fund) announces the registration of the Russian Sputnik V vaccine against coronavirus by the Ministry of Health of the Republic of Nicaragua.

The vaccine was approved under the emergency use authorization procedure without additional clinical trials in the country. Thus Sputnik V is now registered in 6 countries of Latin America.

Sputnik V had been approved earlier in Russia, Belarus, Argentina, Bolivia, Serbia, Algeria, Palestine, Venezuela, Paraguay, Turkmenistan, Hungary, UAE, Iran, Republic of Guinea, Tunisia, Armenia and Mexico.

France insisted that geopolitics isn’t a factor when it comes to making decisions about sourcing life-saving coronavirus vaccines.

During a press briefing on Wednesday, an official in Emmanuel Macron’s office, who asked not to be named in line with protocol, said the French president and Chancellor Angela Merkel were aligned in welcoming any inoculations that meet European Union standards, and that geopolitics plays no role.

The comment came in answer to a question about whether Macron would consider purchasing Russia’s Sputnik V vaccine, which Merkel has said she’s ready to consider using in Germany. At the same time, the French official noted that the Russian vaccine hadn’t yet been approved by bloc.......
