U.S.A. Begins final test with anti- vaccine COVID-19

The world's largest clinical test with anti vaccine COVID-19 kicked off on Monday (July 27th with the first volunteers of the planned 30,000.

The experimental vaccine was produced by the National Institute of Health and the company “Moderna Inc.”, and is one of several possible candidates in the world race for producing a vaccine against the virus.

There is still no guarantee that the experimental vaccine developed by the National Institute of Health and “Moderna Inc.” will guarantee protection from COVID-19.

Volunteers will not know whether they are taking the actual injection or a replica of the vaccine. After two doses, scientists will closely follow which group will suffer more infections as they continue with their daily routine, especially in areas where the virus is spreading uncontrolled.

The company “Moderna” said the vaccine started in Savanah, Georgia, among more than 12 other countries where clinical trials are being conducted throughout the country.

In Binghamton, New York nurse Melisa Harding said she was offered as a volunteer “to do what is due her to help”. “I feel excited” said Mrs. Harding before the vaccine Monday morning.

Several other experimental vaccines produced by China and the University of Oxford, Britain, are in the final phase of several low - rate tests being conducted in Brazil and other countries hit by pandemics.

But the US is seeking to establish a high standard for all tests it will conduct for any vaccine that can be used in the country. Every month, the government-funded COVIID-19 Prevention Network would conduct a new study of any vaccines seen as potential candidates for mass use, each with its 30,000 newly recruited volunteers. Massive studies are not simply to test whether vaccines function, they are necessary to control their safety. Following the same study rules will enable scientists to make comparisons among all vaccines.

Later in August, the US launches final clinical test with Oxford vaccine, which is expected to be followed by clinical evidence from a possible vaccine produced by “Johnson & Johnson” in September and by “Novax” in October, if everything goes according to plans.

The company “Pfixer Inc.” plans to launch its study with 30,000 people this summer. This is considered to be an enormous number of people who will roll up their sleeves in the service of science. “In recent weeks more than 150 thousand Americans completed an online form showing their interest in participating in the study”, says Dr. Larry Corey, virologist at the Cancer Research Institute “Fred Hutchinson” in Seattle, which is helping with the supervision of places where clinical trials are being conducted.

“These tests will include Americans of different generations, they will be multiethnic because they have to reflect the diversity of the United States population.“, Mr. Corey said during a meeting on vaccines last week. He stressed that it is especially important to ensure a sufficient number of volunteers belonging to the African-American community and those originally from Latin America, as he said these are the most hit communities by COVID-19 in the US.

It normally takes years to produce a new vaccine, but this time scientists are setting speed records, viewing the vaccine as the most efficient hope against pandemic.

Until the end of December, it was not known to be there. Vaccinators went into effect on January 10th, when China distributed the genetic sequence of the virus.

Just 65 days later in March, the vaccine produced by the National Institute of Health was tested on people. The first volunteer encouraged others to join clinical trials.

“Actually, we all feel very helpless. We can do very little to fight this virus. Being able to participate in this trial has taught me that I'm doing something“, says Jennifer Haller from Seattle for the agency “AP”. “Prepare for many questions from friends and family about how you are going and many thanks“, she says.

The study in its first phase, attended by Jennifer Haller as well as 44 other volunteers, showed that injections stimulated the immune system of volunteers in a way that scientists believe will ensure protection, with some minor side effects such as short - term, trembling, and body pain. / VOA/
