Mixing and Matching Covid Vaccines Is Examined by F.D.A.

Several discussion participants said Friday that NIH researchers were pleased with the amount of data they gathered to recommend FDA approval for vaccine blending. dr. Ofer Levy, director of the precision vaccination program at Harvard Children’s Hospital in Boston, said many Americans were already on their toes and asked the FDA to intervene.

“In the real world, all these types of combinations and additional boosters already exist, so I think there is an urgent need to help the FDA manage scenarios that are clearly complex and challenging,” he said. “We can’t hide it and I think we should provide guidance to the general public.”

What you need to know about Covid-19 booster photos
What is the purpose of the booster shot?
The FDA has approved booster photos for a select group of people who received a second dose of Pfizer BioNTech vaccine at least six months ago. This group includes: People who are vaccinated over the age of 65 or people living in care facilities. Adults are at high risk for severe COVID-19 because of the underlying disease. Health workers and other people whose work is dangerous. People with impaired immunity are entitled to a third dose of Pfizer or Moderna four weeks after the second injection.

Are people vaccinated with Moderna and Johnson & Johnson?

Diabetes or obesity; Cancer or blood disease; weakened immunity; chronic lung, kidney, or liver disease; Dementia and some disorders. Pregnant women, current smokers and ex-smokers are also eligible.

This is not recommended. For now, Pfizer vaccine recipients are advised to receive a booster shot from Pfizer. Moderna and Johnson & Johnson recipients must wait for a booster dose from this manufacturer to be approved.

Can I get the flu shot at the same time as the Covid vaccination or booster vaccination?
Yes, Sir. According to the CDC, the Covid vaccine can be given at any time, and many pharmacies allow an influenza vaccination to be scheduled at the same time as a booster vaccination.

dr. Amanda Korn, a CDC official, said the FDA could possibly include generic terms in approving vaccines that allow the combination.

“From a public health perspective, it’s clear that in some situations people may need to be vaccinated in different ways,” he said.

The NIH study only looked at antibody levels. Antibody levels alone are not enough to measure how different combinations protect people. dr. As I said, ongoing studies of cellular immune responses are ongoing.

dr. Johan Van Hoff, CEO of Johnson & Johnson, said boosters were desirable and cited limited data on mixing and matching. “This discovery is important, but it is only part of the puzzle, not the big picture,” he told the study.

However, some experts say the evidence still points to a shift between vaccine platforms.

Scott Hensley, an immunologist at the University of Pennsylvania, said, “Questions about the amount of data the FDA needs before making this recommendation?

“I don’t want to be in their shoes,” he added.
