AmericaPharmaceutical company Moderna claims its Covid-19 vaccine is 94.5 percent effective, according to preliminary data from a late-stage trial.
The statement made on November 16, Moderna became the second manufacturer in the US to report vaccine results that far exceeded expectations. Therefore, with the product from Pfizer, the US has two Covid-19 vaccines, which are expected to be approved urgently in December this year.
“Our vaccines can stop Covid-19,” Moderna President Stephen Hoge said. His phase three trial was carried out on 30,000 volunteers. The two injections are 28 days apart. After vaccination, 95 people were infected with nCoV. Among them, only 5 cases were vaccinated, the rest used a placebo.
Eleanor Riley, professor of immunology and infectious diseases at the University of Edinburgh, said: “Having more than one effective vaccine will increase the world’s supply. Hopefully, we can get back to normal life.” year 2021 “.
Both “candidates” were developed using new messenger RNA technology, capable of stimulating the human cell to produce viral proteins. Then the immune system comes into contact with the protein and produces antibodies, the immune cells recognize and destroy the pathogen.
Moderna plans to request urgent approval from US officials next week if sufficient safety data is available.

The advantage of the Moderna vaccine is that it does not need to be stored extremely cold like the Pfizer product, which makes the administration process easier. The first doses can be stored in a normal medical refrigerator at 2-8 degrees Celsius for 30 days.
Moderna’s data also shows that the vaccine prevents severe cases of Covid-19. This is an open question to the Pfizer “candidate”. Of the 95 positive volunteers, 11 were serious. They are all placebo users.
Moderna’s vaccine is part of the US Government’s Rapid Campaign, and the program is expected to produce 20 million shots for the people of this country this year.
“If authorized, we will be ready to ship via Operation Express in a few hours. So that the vaccine can be delivered immediately,” Hoge said.
Most of the side effects of the Moderna vaccine are mild to moderate. But many volunteers also experienced more severe symptoms after the second injection. 10% suffer from severe fatigue, unable to perform normal activities. Another 9% suffer from muscle aches. Moderna said that this situation did not last long. Peter Openshaw, professor at Imperial College London, explains: “These are the predictable responses to an effective vaccine that produces good immunity.”
Pfizer announced that the vaccine it co-produced with German pharmaceutical company BioNTech was 90% effective on November 9. This is considered great news for science and humanity. Phase 3 tests were performed on more than 40,000 people. After vaccination, 94 volunteers became infected with the virus.
To date, there are more than 100 vaccines in development around the world. Twelve “candidates” who participated in the end-stage clinical trial are from the United States, Germany, China, the United Kingdom, Russia, and India. In August, Russia approved the Sputnik V vaccine urgently before completing phase 3 testing. On November 12, Russia’s Direct Investment Fund (RDIF) said Sputnik V was 90% effective and a few days later. “corrected” was 92%, but did not publish detailed data but was “observational.”
