In the United States, they began testing on humans the medicine and vaccine for Chinese coronavirus
Moderna Therapeutics, an American biotechnology company based in Cambridge, Mass., Has shipped the first batch of its COVID-19 coronavirus vaccine to the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH) in Bethesda, Maryland. will prepare a vaccine for testing in humans in April 2020. Writes about this Time.
The vaccine was created just 42 days after Chinese researchers released the genetic sequence of the COVID-19 virus called SARS-CoV-2 in mid-January.
NIH scientists began testing an antiviral drug called Remdesivir, which was developed to fight Ebola in a patient infected with SARS-CoV-2.
The test is the first step in testing a drug for the treatment of COVID-19, and will be conducted by a team from the University of Nebraska Medical Center. The first patient to volunteer for the groundbreaking study is a passenger who was evacuated to the United States from the Diamond Princess cruise ship after they discovered he had a coronavirus. Other people with confirmed disease will also be part of the study.
Remdesivir showed encouraging results in animals infected with two related coronaviruses, one responsible for severe acute respiratory syndrome (SARS) and the other for Middle East respiratory syndrome (MERS).
Volunteers will be randomly assigned to take the drug or placebo intravenously for 10 days. Every two days they will have blood tests, nasal and throat swabs to track the amount of virus in their body. Even if the drug demonstrates some effectiveness in controlling the growth of SARS-CoV-2 levels in the blood, it can help control the spread of infection.

The Moderna vaccine against COVID-19 was developed in record time because it is based on a relatively new genetic method that does not require growing a huge amount of virus.
Instead, the vaccine is packed with mRNA, a genetic material that originates from DNA and produces proteins. Moderna loads its vaccine into mRNA, it encodes the correct proteins of the coronavirus - they are then introduced into the body. Immune cells in the lymph nodes can process this mRNA and begin to produce protein so that other immune cells can correctly recognize and label them for destruction.
This means that this vaccination method can be quickly distributed, saving critical time when a new disease like COVID-19 appears that can infect tens of thousands of people.
