COVID-19 Vaccine mRNA-1273 In US Firm Moderna Shows Positive Results On Healthy Volunteers

8 people who took part in 45 subjects kicked trial in March were tested against the vaccine of COVID-19.

This COVID 19 pandemic situation is giving panic to people, A US-based company, is giving hope to people as they are in the assumption of finding a vaccine

The group of brave and healthy volunteers in the US came forward for this test. US government’s National Institute of Allergy and Infectious Diseases Runs this test. When antigen was inserted, this volunteer is successfully able to create antibodies. Antibodies are a blood protein produced in response to antigen. Antibodies combine chemically with substances which the body recognizes as alien, outer parts such as bacteria, viruses, and foreign substances in the blood. 


Those antibodies then were tested on human cells. While testing this process scientist observes that this process help in stopping the replication of the virus. The vaccine is called mRNA-1273. mRNA-1273 a small snippet of the coronavirus’s genetic code, which is injected into the patient.

The firm’s Chief Medical Officer, Tal Zaks shred that “a total of three doses of the vaccine was tested: low, medium, and high. But as every new vaccine shows some side effects in novel form this vaccine shows redness and soreness in one patient’s arm where the shot was given.”


This was the case when people have given small doses. But when people are given high doses they show high fever and headaches. These symptoms stay for a day. Out of 8 people who received doses of 50 or 100 micrograms were able to develop antibodies. These antibodies are strong enough to defend the virus.

The Food and Drug Administration (FDA), U.S, had already given a green flag to the second phase of trials. The increased amount of doses was tested.

Scientists and medical experts researching the amount of dosage which would show the best results.

Nonetheless, Zaks said, If the trials go well, this vaccine would be available for the major part of the world for use. But this vaccine will be available by the end of this year or early 2021, 

More than 4.6 million people were infected worldwide and 317000 were killed. If this vaccine came perfectly then this will be the biggest achievement.
