Who is developing the vaccine at the moment?
- USA
Today, July 15, it became known that the American
Experimental vaccine against coronavirus,developed by Massachusetts-based biotech company Moderna, triggered an immune response in early-stage clinical trials. The study found that some antibodies were produced after one dose of the vaccine, but a second dose was required four weeks later, after which the vaccine produced a strong immune response in all 45 volunteers. No serious side effects were found.
On Wednesday, July 14, Reuters, citing a sourcein the administration of President Donald trump reported that US pharmaceutical companies will begin mass production of a vaccine against coronavirus in four to six weeks. By the end of 2021, the country plans to release 300 million doses of the drug.
- Russia
Clinical trials of the coronavirus vaccine on the first group of volunteers showed the safety of the new drug, the Russian Ministry of Defense announced today, July 15.
Clinical trials of the drug conductedThe Ministry of Defense together with the National Research Center for Epidemiology and Microbiology named after N.F. Gamalei. All 18 volunteers completed their participation in the studies and were discharged from the branch of the Main Military Clinical Hospital named after N. N. Burdenko, the report said.
However, during tests carried out inSechenov University Volunteers experienced an increase in temperature in the first days after the injection. According to Anna Gutkina, who took part in the tests, in the first two days she had a temperature of 38 and chills. These symptoms were relieved with paracetamol. The woman noted that she had no loss of smell.
In total, almost 50 types of coronavirus vaccines are being created at the current stage of the pandemic in Russia. All of them are developed both by state research centers and private research companies.
- China
One vaccine in China already licensedfor use in the Armed Forces. This is a fifth type of adenovirus vector vaccine. In the stage of preclinical trials in the world are 132 drugs.
A week ago, the country endedconstruction of a workshop for the production of a coronavirus vaccine. As the People's Daily online newspaper writes with reference to the China National Biotechnology Group, the production workshop located in Wuhan will annually produce and produce 100 million vaccines against COVID-19. Also, specifically for testing, Chinese scientists have created genetically modified mice susceptible to COVID-19, on which they can test vaccines and drugs against coronavirus infection. Testing continues.
- Italy
In Italy, the second country after China,victims of coronavirus - scientists are also working on a cure. The vaccine is being tested by Takis. So far we are talking about animal testing. The medicine is based on a fragment of the genetic material of the virus.
If the test results are satisfactory, it will be possible to begin testing on humans. However, this will most likely happen only in the fall, company representatives say.
- Japan
At the beginning of July it became known that the Japanesedeveloper of a DNA vaccine against COVID-19, AnGes Inc. began clinical trials on two groups of 30 volunteers. The safety of the vaccine was confirmed during clinical trials. The second phase of testing the coronavirus vaccine will last until July 28, after which the Gamaleya Institute will submit for registration.
DNA vaccine trials conducted on 30 healthyadults at the Osaka University Hospital. This vaccine contains DNA of a spike protein, which is located on the surface of the virus. Researchers suggest that the immune system of the vaccinated person will begin to produce antibodies that will prevent coronavirus infection.
Clinical trial participants willvaccinated twice with an interval of two weeks. At the same time, 15 people will receive a larger dose of the vaccine, while others will be given a smaller one. Then scientists will analyze the results of patients in both groups.
How are sick people treated now?
Please note that at the moment there is no specific treatment for coronavirus, only symptomatic. The vaccine is under development. Therefore, if you are sick, you must:
- observe bed rest;
- drink plenty of fluids;
- rinse your nose with saline solutions;
- regularly ventilate the room;
- bring down heat if necessary.
