Third dose of COVID-19 vaccine could boost protection in transplant patients | St. Louis News Headlines – St. Louis, Missouri

(CBS NEWSPATH)-A Johns Hopkins study found that organ transplant patients who received a third dose of the COVID-19 vaccine may enhance their protection.

Gillian Rudd received a new kidney and pancreas three years ago. As a result, dual-organ recipients are not particularly vigilant to protect themselves in a pandemic. “I’ve already compromised and have navigated the world in a much more cautious way,” says Rudd.

Transplant patients take drugs that suppress the immune system to prevent rejection, which can affect the response to the vaccine. Rudd received the COVID-19 vaccine twice, if possible. Then I was disappointed. “I didn’t mount measurable antibodies,” she says.

Rudd participated in a study at Johns Hopkins Medicine and followed 30 transplant patients who received a third vaccination. One-third of the negative antibody levels after the second dose increased after the third dose. All patients with low levels of antibody increased their immune response after boost immunization.

“The real impact of our somewhat preliminary findings is the faint light of hope that we can achieve the immune response of immunosuppressed people,” says Dr. Dolly Segev, a transplant surgeon at Johns Hopkins Medicine.

Dr. Segev led the research. His previous studies show that half of transplant patients do not respond to antibodies after two doses of the vaccine, and half have lower levels than people with a normal immune system.

“We are confident that we will understand how to protect them for transplant patients. It is not time to celebrate the freedom associated with vaccines,” says Dr. Segev.

Rudd became antibody positive. “My donor’s parents were very kind and decided to give me a second chance in life, so there was nothing to prevent me from getting the vaccine,” she said. say. Rudd says she has hope for the future.

Researchers say there is a risk in getting a third shot, which has not been carefully studied. So that’s what they are watching very carefully.
