According to two new studies, their results published in the New England Journal of Medicine (NEJM), the Moderna vaccine may be one of the effective vaccines against some new coronavirus mutations, but according to the CDC, the Moderna vaccine may cause more health complications than other vaccines.
In two different studies, the Moderna vaccine was effective against some mutated coronavirus, and according to the two studies, it was noted that the Moderna vaccine may be effective in resisting some emerging coronavirus mutations, and it may provide protection against the virus for 6 months after taking it.
The first study
The first study was conducted by researchers at Duke University of America (Duke University), and although the researchers noticed that the antibodies generated by the Moderna vaccine may be somewhat weak when it comes to resisting one of the Corona mutations discovered in the United States of America, the vaccine remained It is effective against said mutation.
The second study
The second study was conducted jointly by researchers at the National Institute of Allergy and Infectious Diseases (NIAID) and Emory University, and the researchers observed that the presence of antibodies continued to be elevated in the body for at least 6 months after receiving the second dose of Moderna vaccine.
The results of these studies came to add another positive point related to the use of this vaccine, as a previous study had shown that the Moderna vaccine may be effective in protecting against the British mutation, which has become the prevailing mutation in some countries of the world.
CDC: Moderna vaccine is effective but has complications
Despite these promising results, a report issued by the CDC showed that taking the Moderna vaccine may cause health complications that are more varied and severe than complications that other vaccines such as Pfizer may cause.
These are some of the health complications that have occurred in some of those who received the first dose of the Moderna vaccine:
Redness and pain at the injection site: These complications occurred in 74% of the people who received the Moderna vaccine, compared to 65.4% of the people who received the Pfizer vaccine.
Fever, chills, and headache: These complications appeared in 51.7% of people who received the Moderna vaccine, compared to 48% of people who received the Pfizer vaccine.
An increase in the difference between the percentage of health complications recorded and that resulted from the two mentioned vaccines was recorded after taking the second dose of the two vaccines, so the Moderna vaccine recorded more health complications.
