COVID-19 vaccine begins final test with 30,000 volunteers


The world’s largest COVID-19 vaccine study began on Monday. A total of 30,000 employed volunteers will help test the effectiveness and safety of a shot developed by the National Institutes of Health and Drug Maker Modern.

Volunteers will receive two each The dose Of a shot. They won’t know if they are getting the real vaccine or the wrong version. The scientists will then follow the volunteers closely as they go about their daily activities. They want to see which group experiences higher rates of infection, especially in areas where the virus is still spreading uncontrollably.

There is still no guarantee that the experimental vaccine will provide protection. The study is expected to answer that question.

Dr. Anthony Fauci is the country’s top infectious disease specialist with the NIH. He told the Associated Press, “Unfortunately for the United States, we have a lot of infections right now” to help get that answer.

Volunteers from more than 80 testing areas across the country will participate in the study. Modern said the first vaccine was given Monday morning in Savannah, Georgia.

Many other vaccine candidates made by Oxford University in China and Britain started later –Forum Study earlier this month. Those studies included fewer volunteers than in the US. They are being transported to Brazil and other hard hit countries.

The US government requires its own trials of any vaccine used in the country. If the vaccine works, then the objective is not just to test. Also check if it is safe.

Through the government-funded COVID-19 prevention network, the US plans a new study for vaccine candidates every month through the autumn. Each will consist of 30,000 newly selected volunteers. The hope is that, using the same rules for each study, scientists will be able to easily compare vaccines.

In August, the US will complete its final phase of the Oxford University Vaccine Candidate. The Johnson & Johnson vaccine study will begin in September and in November from Novavax. Drug maker Pfizer also plans to conduct its 30,000-person study this summer.

Volunteers are needed to test possible vaccines. But in recent weeks, more than 150,000 Americans have registered to volunteer for the study, Dr. Larry Corey says. He is with the Fred Hutchinson Cancer Research Institute in Seattle, Washington.

“These tests … are needed Reflect Diversity of the United States population, ”Corey said at a vaccine meeting last week.

He said it is important that the study include people from different age groups and populations that have been particularly affected by COVID-19, including blacks and Hispanics.

It normally takes years from beginning to end to make a new vaccine. But this time, scientists are setting speed records. They believe that vaccination is the world’s best hope against the virus.

The new coronavirus was not known to exist before the end of December. Vaccine manufacturers had to operate on January 10, when China shared the genetic sequence of the virus.

Just 65 days later, American researchers gave the first test vaccine by NIH and Modern to Jennifer Hayler, a volunteer in Seattle, Washington. Holler is urging others to volunteer now.

He told the AP, “We all feel very helpless right now. There is little we can do to deal with this virus. And being able to participate in this test made me understand, that I am doing something. “

Holler and 44 others were involved in that initial study. This was revealed by experimental COVID-19 vaccine produced antibodies in a small group of healthy people. It briefly caused some minor side effects. fever, Chills And pain in the injection area. Initial trials of other major vaccine candidates have yielded similar promising results.

It would take several months for the first data to come from the modern to the 30,000-volunteer test, followed by Oxford.

Until then, Holler will continue to cover the face in public. She is still following the same physical disturbance she advised for everyone. “I don’t know if there is a possibility that this is the exact right vaccine,” she said. “But thank goodness there are many other people struggling with it right now.”
