Getting a COVID recall in NJ? Rutgers doc talks about “mix-and-match”


Now that the CDC recommended booster doses of the three COVID-19 vaccines approved by the United States, many may wonder how the agency concluded exactly that those who were vaccinated may receive a booster done by a company different from their original regimen.

According to Dr. Shobha Swaminathan, associate professor at Rutgers New Jersey Medical School, the boosters give vaccinees “flexibility”, and are safe and effective, as shown by clinical trial data.

Not only that, Swaminathan said, but in those whose antibody levels may have declined since receiving their primary vaccine series, a booster – according to its name – may restore those levels to what they were. , see more.

Swaminathan said preliminary research even suggests that for those who have received the Johnson & Johnson single-dose vaccine, following up on one of the other manufacturers’ vaccines, known as the heterologous booster, may produce more antibody than a J&J booster.

“If you initially received the J&J vaccine, you are probably better off getting a booster with one of the messenger RNA vaccines, either the Moderna vaccine or the Pfizer vaccine,” Swaminathan said.

At the stage of the primary series, Johnson & Johnson was considered to have an advantage because he was unique. But now the CDC has recommended boosters for everyone who received this brand, rather than just the high-risk groups who received the others.

“Since everyone who got the one-and-dones has to get a ‘second hit’ or a booster, it’s a level playing field because you can get a booster with one hit,” Swaminathan said.

So what about being “completely boosted”? Full antibody protection is considered to be achieved two weeks after receiving the Johnson & Johnson injection or a second dose of Moderna or Pfizer.

But the immune response to a booster could be seen in as little as 10 days, Swaminathan said, because unlike the initial doses, those who were vaccinated now have a COVID antibody base to draw on.

“You really needed to wait the full two weeks after your second shot to be ‘fully protected’, didn’t you? ” she said. “But right now, those who go looking for boosters are not starting from scratch.”

Swaminathan suggested that the antibody response created by the Pfizer and Moderna vaccines, despite the groundbreaking cases caused by the Delta variant, has been so strong that boosters are not requested at this time for recipients without underlying conditions.

Still, she said waiting in line for an extra shot wasn’t totally unnecessary for these people.

“We all know people around us, young and healthy people who want to receive the booster, and that’s okay. And I think this data shows that you won’t have significant poor results until. now, ”Swaminathan said.

If you have any questions, Swaminathan said talk to your doctor, read the latest CDC guidelines, and if you get a booster and have an unwanted side effect, report it.

The recall decisions that were made are the right ones, she said, but were based on much smaller studies, so more information is still needed.
