The second vaccine, which has reached a critical milestone, is 94.5% effective in protecting people from the Covid-19 virus, according to Moderna Inc.
KEY POINTS
- BioNTech said in a major clinical trial that the covid-19 vaccine was more than 90% effective.
- Pfizer plans to use the Food and Drug Administration to set up a potential distribution.
- COVID-19 vaccines developed in China and Russia have already been administered.
- Moderna’s vaccine, like Pfizer’s, uses a new technology called messenger RNA.

Of the 95 people who developed Covid-19 with symptoms so far, 90 received only placebo and five Moderna vaccine, the company said Monday. The findings move the vaccine closer to wider use because they indicate that it may be effective in preventing symptomatic disease, including severe cases.
The vaccine also showed signs of being safe, although researchers and regulators will have to wait for the study’s complete safety data, which is expected by the end of November. Moderna said they plan to ask federal health officials in early December to clear the vaccine. Federal officials said Friday that levels may be available that month.
It could make Moderna’s Covid 19 vaccine one of the first to be distributed in the United States, where cases of coronavirus have been reported.
“We may be in a place where there is a vaccine that can have a big impact on preventing serious illness,” Moderna CEO Stephane Bancel said in an interview. “It will be an incredible victory against this nasty virus.”
Anthony Fauci, director of the Institute of Modern Allergy and Infectious Diseases, says the high efficacy rate of the Moderna vaccine may be an excellent tool to help end the infection.
“These are very impressive and very inspiring and amazing results,” Dr Fauci said.
Earlier this month Pfizer Inc. and BioNTech SE said in a major clinical trial that the covid-19 vaccine was more than 90% effective in protecting people from the covid-19 symptom.
This month’s U.S. Pfizer plans to use the Food and Drug Administration to set up a potential distribution to start later this year.
Although preliminary, the initial results for both vaccines suggest that researchers could develop effective Covid-19 scenarios, which could be a great help in controlling the infection.
Moderna’s initial data from the first 95 people in 30,000-subject experiments that developed Covid-19 with symptoms were reviewed by a team of independent researchers overseeing the study. The findings provide only an approximate snapshot of whether the vaccine works.
The company plans to publish further results against infections that do not produce symptoms and symptoms in specific groups such as the elderly.
Researchers will not have complete performance data until a total of 151 people develop Covid-19 symptoms in the experiment. Moderna expects this to apply to government recognition, Mr Bancel said. The company said the performance rate may change when more cases are analyzed, but the initial numbers were higher than the high bar it set for initial results.
Both the Moderna and Pfizer Covid-19 vaccines are highly advanced in Western development, with AstraZeneca PLC, Johnson & Johnson & Novavax Inc.
Covid-19 vaccines developed in China and Russia have already been administered, although they have not completed the final phase of testing.
Moderna’s vaccine, like Pfizer’s, uses a new technology called messenger RNA. It works by providing genetic instructions that teach human cells to make a protein similar to a protein found on the surface of the coronavirus. It triggers an immune response designed to protect vaccinated individuals from later exposure to the real virus.
Cambridge, Mass., Biotech, Moderna, the forerunner of MRNA, has never brought a drug or vaccine to market. The National Institute of Allergy and Infectious Diseases worked with the company to develop its vaccine.
The federal government, under the Operation Warp Speed initiative, has given Moderna about $2.5 billion to support its vaccine research and testing and to purchase at least 100 million doses of the vaccine.
Phase 3 is, in the late study of its vaccine, those in approximately 100 U.S. locations were given two doses of the vaccine or placebo at four-week intervals. The researchers monitored Covid-19 symptoms at least two weeks after the second dose.
When 53 people came up with symptom Covid-19, the design of the study called for an independent panel to conduct the first interim analysis of performance. Moderna said the first analysis involved significantly more people because of the recent increase in Govt-19 cases nationwide.
Of the 95 cases reviewed, 11 were severe, all of them in placebo recipients, Moderna said.
Due to an urgent need, the FDA plans to approve the Covid-19 vaccine faster than standard in public health emergencies. Technically, the authorization would be for emergency use instead of a standard approval.
The FDA wants to see at least half of the 30,000 people under investigation under two-month security surveillance, a milestone that Moderna expects by the end of November. At the initial appearance, the company said no significant safety concerns were reported, and the vaccine was generally well-tolerated, with injection-site pain in some people after the first dose, and fatigue, headaches and joint pain in the second.
If regulators approve the vaccine, the initial dose will be enough for 20 million or 10 million people by the end of this year, Moderna predicts. The federal government may decide to vaccinate health workers and first responders first, while other segments of the population are in stages until more is done next year.
Moderna is working with contract manufacturers to increase production so it can generate between 500 million and one billion next year. The contract has the option of 400 million in addition to the initial 100 million.
Moderna also plans to gain recognition in other countries and has signed distribution agreements with several companies.
