Regarding the modelna's new corona virus vaccine, groups such as the National Institute of Allergy and Infectious Diseases in the United States announced experimental results that it was effective against mutant viruses such as Delta strain, which has strong infectivity even six months after inoculation. Did.
This was published in the scientific journal "Science" by groups such as the National Institute of Allergy and Infectious Diseases in the United States.
The group asked 24 people who received the modelna vaccine twice to donate blood after a certain period of time, and investigated the effect of the vaccine using an artificial virus that reproduced the characteristics of the new coronavirus.
As a result, out of the blood of 24 people, the effect of suppressing the virus even six months after the second inoculation was confirmed in the United Kingdom, 100% against the new coronavirus before the outbreak of the mutant virus. "Alpha stock" accounted for 96%, and "Delta stock" confirmed in India also accounted for 96%.
On the other hand, it was 54% lower than the beta stock confirmed in South Africa.
In addition, the neutralizing antibody levels peaked 2 weeks after the second inoculation and gradually decreased.
The group said that this vaccine could be recommended for the current mutant virus, and that the data would be useful for the third inoculation study as the level of neutralizing antibodies declines over time. increase.
