The WebMD website on Monday has said 45 participants have received a new vaccine trial for COVID-19.
The vaccine which was produced by Moderna, a Massachusetts-based company was given to 45 participants, and all of them developed detectable antibodies.
The vaccine called mRNA-1273 is in three different dosage levels of 25, 100 and 250 micrograms.
The company further revealed that eight people who received doses of 25 and 100 micrograms in March responded best, developing antibodies that were just as high or higher than the antibodies found in people who had gotten the coronavirus and then recovered.
The company added it plans to move ahead with the next two phases, in which larger numbers of people will be tested this year.
The vaccine uses something called the messenger RNA approach.
“I think the totality of science tells us that this is the right antigen and it should be protective,” Tal Zaks, Moderna’s chief medical officer said.
The testing is being done in coordination with the National Institutes of Health and the National Institute of Allergy and Infectious Diseases.
