The third dose against Corona .. Can it be taken from a different vaccine?

In light of the talk about booster doses of corona vaccines, a question arises as to whether it is acceptable to receive the third booster dose of a different type from what the person obtained in the first and second doses.

The US Food and Drug Administration (FDA) is still skeptical about the option of mixing different types of vaccines, due to a lack of data, according to a report published by NBC.

Dr. Doran Fink, deputy director of the FDA’s Vaccine Division, said that the decision on booster doses includes Pfizer-Penontech recipients at this stage, so those who are eligible for the third dose are those who receive two doses of the Pfizer vaccine.

This necessarily means that those receiving the Moderna or Johnson & Johnson vaccines have to wait.

Doctor Vivek Murthy, during a recent conference at the White House, sought to reassure the recipients of Moderna and Johnson & Johnson doses, and indicated that “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.” possible, with a view to making recommendations about the booster dose.”

He said it was interesting to see the mixing and mixing of vaccines between Pfizer and Moderna with a dose of Johnson & Johnson.

Dr. Kristina Rostad of Emory University School of Medicine, told NBC News that she expects approval of booster doses in the near future, especially as they are similar and share the technology used in this vaccine.

She adds that so far it has not been approved for mixing vaccine doses, especially since the information available on this matter is still very limited.

The National Institutes of Public Health is still in the second phase of vaccine mixing trials, as it is in the first phase of testing.

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.

And the US Food and Drug Administration recently agreed to give booster doses of the Corona Pfizer vaccine to specific groups, for those over 65 years old.

Pfizer had requested that it be given approval to give booster doses to people over 16 years old.

The committee refused to approve granting these vaccines to all due to the “lack of safety data” regarding booster doses, and some of them raised doubts about granting them to everyone and indicated that they should target specific groups only, according to a report published by “BBS News”.

The committee agreed to grant the booster doses to the category of people “most at risk of the virus”, or those who have incurable diseases.
