Questions arise about the effectiveness of corona vaccines, and people usually ask, “What vaccine should I take to provide myself with higher immunity and be healthy?”
The Pfizer and Moderna vaccines are the best, scientists say, but when the comparison is fine-tuned, down to the smallest detail, one must be better than the other.
Since the start of the crisis, 221 million doses of Pfizer have been distributed, compared to 150 million doses of Moderna in the United States.
A report published by the New York Times indicates that although the efficiency and effectiveness of these vaccines are similar, the data shows that Moderna’s vaccine may be better than that of Pfizer, for several reasons.
Recently released data from the Center for Disease Control and Prevention (CDC) showed that the effectiveness of Pfizer vaccines decreased after about four months to 77% instead of 91%, while Moderna’s vaccine did not show any effect. decrease in effectiveness during the same period.

The journal report says that if a gap in vaccine efficacy persists, it may have implications for the vaccine booster controversy.
Scientists who were initially skeptical of the differences between the two vaccines are now convinced that there is a divergence between the vaccines, which can have different effects.
Natalie Dean, a biostatistician at Emory University in Atlanta, explains that at first we looked at mRNA vaccines that worked similarly, but then found differences between them, although the difference was not. significant, but it persists.
And she believes both vaccines work effectively in preventing serious illness and recovering from a corona infection.
Dean added that the results of these numbers can be affected by different factors, including the age of the vaccinated population, where they live and the time between doses.
John Moore, a virologist, told the New York Times: “It is possible that there is a real difference that reflects the difference between the two vaccines, but the question remains, how important is this difference?
And that “it is not appropriate for people who have taken the Pfizer vaccine to panic because they have received a vaccine whose effectiveness may vary slightly over time.”
The report explains that the finer details will become more apparent over time, at which point vaccines should be compared directly in a study designed for this purpose.
Health experts believe that the United States Food and Drug Administration (FDA) will issue a permit to use the Pfizer vaccine for children under the age of 12.
And the United States Food and Drug Administration recently agreed to give booster doses of the Pfizer Corona vaccine to specific groups for those over 65.
Pfizer had requested permission to give recalls to people over the age of 16.
The committee refused to approve the granting of these vaccines to all due to the “lack of safety data” regarding the booster doses, and some of them questioned their granting to all and indicated that they should only target specific groups, according to a report by “BBS News.”
The committee agreed to give the booster doses to the category of people “most at risk of contracting the virus”, or those with incurable diseases.
The issue of the booster vaccines will also require approval from the Centers for Disease Control and Control “CDC”, which is expected to be discussed next Wednesday, as it also signs approval to give it to the elderly, residents of nursing homes. and those working on the “front lines” in health care.
In the coming days, the FDA and CDC will review requests to grant the Johnson & Johnson and Moderna vaccines at booster doses.
