Moderna vaccine claims at least 3 months of immunity with the lastest COVID-19
A study on Thursday revealed that the Moderna Covid-19 vaccine, which the company reports is 94 percent effective recently, produces powerful antibodies to the human immune system, which remain at least three months long term.
The immune response of 34 young and old adult participants in the first stage of a clinical trial was studied by researchers at the National Institute for Allergic and Infectious Diseases (NIAID), which developed the drug jointly.
Writing in the New England Medicine Journal they said that, “slightly over time, as expected, antibodies that stop the invasion of human cells by the SARS-CoV-2 virus deteriorate, but remained elevated 3 months after the booster vaccination.”
The mRNA-1273 vaccine is administered in two 28-day injections.
Though the number of antibodies in the study subjects has faded over time, there is no need to worry about that.
Director of NIAID Anthony Fauci et al. said the immune system will most likely remember the virus when reexposed and produce new anticorps later.
The study has shown encouragingly that the vaccine activated a type of immune cell that is supposed to aid in the memory response but that this will only be confirmed by a longer-term study.
The virologist Benjamin Neuman, a Virologist at Texas A&M University-Texarkana, said that the positive results of the study are evidence that a relatively strong antibody response remains after 90 days of the second dose of the vaccine.
“The number of antibodies made by the vaccine in younger patients was higher than in older patients, but even patients aged up to 70 years had reasonably strong immune responses.”
On December 17, the Moderna vaccine would be examined by the Food and Drug Administration’s advisory committee (FDA) and could soon after be lit green for emergency approval.
It bases on a new technology using genetic material in the form of mRNA, like another vaccine produced in Pfizer and BioNTech (messenger ribonucleic acid).
The mRNA injected into the arm is covered in a lipid molecule whereby cells within our muscles build the coronavirus surface protein.
This leads to the belief that the immune system has been infected with a microbe and trains it to make the correct antibodies if it is confronted with the real virus.
