Since last year, Corona vaccines have been a window of hope for the whole world, as they could end Covid-19. Although there appears to be a need for a vaccine booster dose, the more important question arises: can the third dose of a different vaccine be taken from the first and second doses?
In this context, and according to a report published by NBC, the US Food and Drug Administration remains skeptical about the option of mixing different types of vaccines, for lack of data.
For his part, the Deputy Director of the Department of Vaccines of the United States Food and Drug Administration, Dr Doran Fink, said: “The decision on booster doses includes those who received Pfizer-Biontech vaccines at this time. stage, and therefore those eligible for the third dose are those who have received two doses of the Pfizer vaccine. “
This means that those who have received the Moderna or Johnson & Johnson vaccines will have to wait.
reassuring message
For his part, Dr Vivek Murthy, at a recent White House conference, sought to reassure recipients of Moderna and Johnson & Johnson doses by stating: “Your health is absolutely important, and we must make sure that you are protected against Covid. -19, so the Food and Drug Administration is working with Moderna and Johnson to process the data as soon as possible with a view to making booster dose recommendations.

In turn, Dr Kristina Rostad of Emory University School of Medicine told NBC News that she plans to approve the granting of enhanced doses in the near future, especially since it is similar and shares the technology used in this vaccine.
limited information
Rostad added that so far it has not been approved for mixing vaccine doses, especially since the information available on this is still very limited.
Dr William Moss, of Johns Hopkins University, said there was no immunological reason to believe that mixing the two vaccines would be a problem in any way, especially for the Pfizer and Moderna vaccines. . He found it interesting to see the mixing and mixing of vaccines between Pfizer and Moderna with a dose of Johnson & Johnson.

It should be noted that the United States Food and Drug Administration had approved the administration of booster doses of the Pfizer vaccine to people over 65 years of age. Moderna has also applied for a license to administer a third booster dose of its vaccine.
