"Moderna" announced that it submitted a request Monday to the regulators in the United States and Europe to use its Corona vaccine in emergency situations, after the final data of the experiments confirmed that it is effective against the virus by up to 94%. Moderna confirmed that the effectiveness of its vaccine is uniform for all ages, races and races.

The data confirmed that the results of the third phase of experiments that were conducted on 30,000 people indicated that the vaccine is 100% effective in preventing severe symptoms due to Corona, and by 94% in terms of preventing disease on a large scale.

The company stressed that it did not discover serious safety concerns, and that no new serious side effects appeared in the vaccinated volunteers, as the side effects were limited to injection site pain, headache and a feeling of fatigue.

Moderna indicated that the US Food and Drug Administration may meet to consider the vaccine on the seventeenth of December.

The company expects to ship 20 million doses of the vaccine to the United States by the end of the year, which will suffice to 10 million people. It is required to get two doses of it.

On the other hand, the US Department of Health said that it is possible to distribute two Corona vaccines before Christmas. Assistant Minister of Health Admiral Brett Girwer stated that 80% of the benefit of the "Covid-19" vaccine can be obtained by vaccinating only a small percentage of the population.

Gerwier said: If the United States can vaccinate the most vulnerable groups, such as residents of long-term care facilities, the elderly and minorities, then surely 80% of the benefit of the vaccine can be obtained.

He added: There should be enough vaccine by the end of the year to immunize 20 million Americans, and the rest of America will get it in the second or third quarter of 2021.

The groceries!

The US health authorities will rely heavily on grocery stores and pharmacies to distribute the first batches of vaccines, and the process will begin as soon as they are approved, which is expected this month, but the distribution issue will also face several challenges.

According to the Wall Street Journal, the US Centers for Disease Control and Prevention, affiliated with the Ministry of Health, will distribute vaccines through its centers. The Ministry of Health agreed with dozens of grocery chains and pharmacies to provide their customers with these vaccines.

Among the most prominent distribution points that the Ministry of Health agreed with were: Kruegger and Albertsons stores and CVS pharmacies.

The owners of these stores and pharmacies believe that they are in a good position to provide vaccinations, because they are located near residential areas and their pharmacies regularly provide vaccinations against other viruses such as influenza.

Grocery stores are now providing freezers, thermometers, and other medical equipment to manage the process. However, there will be obstacles in poor rural areas, according to a report by the Washington Post. Among the obstacles also are that these places suffer from a shortage of workers in medical clinics, in addition to the pressure that pharmacies are subjected to.

Some believe that the distribution of vaccines will be more difficult than the testing campaigns that were carried out in the parking lots of grocery stores and pharmacies.

What is the maximum period during which Corona remains alive in the body?

A recent study found the period during which the emerging corona virus remains present in various body fluids and secretions, and the period during which the virus is viable. The scientists studied the "viral spread" of "corona", which is the process of virus reproduction inside the body and then its release into the surrounding environment. The researchers also studied the period during which this virus is "viable", and the period during which its remnants are present. Any genetic material for it is present, but it is not alive and does not cause infection. The researchers found that the average duration of the "virus RNA splash" was:

17 days in the "upper respiratory tract" and its secretions as mucus.

◄ 14.6 days in the "lower respiratory tract" and its secretions such as sputum.

◄ 17.2 days in stool.

16.6 days in serum samples.

As for the "maximum duration of scattering", it was:

83 days in the upper respiratory tract.

59 days in the lower respiratory tract.

◄ 126 days in stool.

60 days in serum.

No study discovered the presence of a "live virus" after the ninth day of illness, despite the persistence of high viral loads.
