In 2019, a Florida woman named Lee Mercker became the first patient to kill off early-stage breast cancer with the help of a promising new vaccine. Mercker, from Jacksonville, was the first human test subject of a clinical trial for a vaccine that helps the body fight cancerous cells. The vaccine has reportedly removed cancer cells and prevented their recurrence. Dr. Knutson from the Mayo Clinic revealed that they've begun testing the vaccine on two more patients and are looking for more trial subjects.

What You'll Learn
Lee Mercker, the first patient
Lee Mercker, a resident of the Jacksonville area in Florida, was diagnosed with a very early stage of breast cancer in March. Despite maintaining a healthy and active lifestyle, she was stunned to receive the diagnosis. She said, "I was healthy. That's why I was mad. I was stunned, and everyone around me was more mad and more stunned."
Mercker went to the Mayo Clinic in Jacksonville to start treatment, but her doctor offered her a chance to participate in a clinical trial for a new breast cancer vaccine. The vaccine aimed to fight off early-stage breast cancer and prevent future occurrences. Mercker decided to take the opportunity and signed up for the trial. She became the first patient and the first human test subject for this experimental vaccine.
The vaccine proved successful in eliminating cancer cells and provided evidence of the immune system fighting the tumour. Dr. Keith Knutson from the Mayo Clinic Jacksonville said, "We saw some evidence of elimination of the tumor, as well as some evidence of the immune system crowding in." Mercker's results were exactly what the team had hoped for, and the success of the trial in its first human test subject was groundbreaking.
Despite being cancer-free, Mercker still underwent a double mastectomy to ensure the complete removal of cancerous cells. Her removed breast tissue can now be studied for further results. Mercker expressed her feelings about the experience, saying, "I feel like I walked on the moon. I worked in an industry with tons of women and I saw all kinds of stories, and it'd just be really nice to stamp this [breast cancer] out."
The success of the trial has significant implications, and Dr. Knutson and his team have started testing the vaccine on two other patients while also looking for more trial subjects. The Mayo Clinic is also working on several other vaccines aimed at preventing and beating cancer.

Experimental vaccine
Lee Mercker, a Florida resident from the Jacksonville area, was diagnosed with an early stage of breast cancer in March 2019. Despite leading a healthy and active lifestyle, she decided to participate in a clinical trial for a new breast cancer vaccine at the Mayo Clinic in Jacksonville. The experimental vaccine aimed to fight off early-stage breast cancer and prevent its future occurrence.
The vaccine reportedly removed cancer cells and showed promising results. According to Dr. Keith Knutson from the Mayo Clinic Jacksonville, they observed "evidence of elimination of the tumor, as well as some evidence of the immune system crowding in." Mercker's results exceeded the team's expectations, especially considering she was their first human test subject.
The vaccine worked by stimulating the patient's immune response, enabling immune cells like T-cells to attack the cancer. This approach holds potential in fighting cancerous cells and preventing their recurrence. Despite the successful trial, Mercker still underwent a double mastectomy to ensure the complete removal of cancerous cells, as the vaccine was still in its experimental stage.
Following the encouraging outcomes of this trial, the team has started testing the vaccine on two additional patients and is actively seeking more participants for further trials. The success of this experimental vaccine represents a significant step forward in the ongoing battle against breast cancer, offering hope for innovative treatments and improved patient outcomes.

Cancer cells removed
Lee Mercker, a Florida resident from the Jacksonville area, was diagnosed with an early-stage form of breast cancer in March. Despite maintaining a healthy and active lifestyle, she opted to participate in a clinical trial for a new breast cancer vaccine at the Mayo Clinic in Jacksonville. The vaccine aimed to fight off early-stage breast cancer and prevent its future occurrence.
Mercker's doctor, Dr. Knutson, revealed that the vaccine had achieved the desired outcome in its very first human test subject. The vaccine successfully eliminated the tumour and stimulated the immune system to crowd in and attack the cancer cells. "We saw some evidence of elimination of the tumour, as well as some evidence of the immune system crowding in," said Dr. Knutson.
Mercker expressed her emotions about the diagnosis, stating that she was stunned and angry despite her healthy lifestyle. She shared the impact of her decision to join the clinical trial, saying, "I feel like I walked on the moon. I worked in an industry with tons of women, and I saw all kinds of stories. It'd just be really nice to stamp this [breast cancer] out."
Despite being cancer-free due to the vaccine, Mercker underwent a double mastectomy to ensure the complete removal of cancerous cells as the vaccine was still in the trial phase. Her removed breast tissue will be studied for further research, contributing to the advancement of cancer treatment. Dr. Knutson and the team at Mayo Clinic have begun testing the vaccine on two additional patients and are actively seeking more trial subjects.

Double mastectomy
A double mastectomy is a surgery to remove both breasts at the same time. It is a major procedure that usually requires a short hospital stay of one or two nights and a longer recovery time of a few weeks to several weeks. The recovery time depends on the complexity of the surgery and whether breast reconstruction is performed simultaneously. With reconstruction, the surgery can take up to 6-10 hours, and recovery may take 4 to 8 weeks. Without reconstruction, recovery can be shorter, around 3 to 4 weeks.
There are several types of double mastectomy procedures:
- Prophylactic bilateral mastectomy: This is a preventive treatment for individuals at high risk of developing cancer in both breasts.
- Contralateral prophylactic mastectomy: This involves removing both breasts when cancer is present in one breast. The removal of the opposite breast is preventive.
- Simple double mastectomy: This involves removing both breasts entirely without plans for reconstruction.
- Modified radical double mastectomy: In addition to removing both breasts, this procedure also removes several lymph nodes under the arms to test them for cancer.
- Skin-sparing double mastectomy: The surgeon removes all breast tissue while sparing as much of the breast skin as possible.
- Nipple-sparing double mastectomy: This procedure removes both breasts but keeps the skin, nipples, and areolas intact. The preserved skin and nipples can be used for breast reconstruction.
The side effects of a double mastectomy can include swelling in the surgical area and other parts of the body, numbness in the upper arm and chest, changes in breast appearance, and postmastectomy pain syndrome (PMPS). The risks associated with the surgery include infection, bleeding, and nerve damage, and these risks are doubled compared to a single mastectomy.
In the context of the trial vaccine for breast cancer in Florida, Lee Mercker underwent a double mastectomy after participating in the clinical trial. Despite the vaccine's success in eliminating cancer cells, Mercker opted for the surgery to ensure the complete removal of cancerous cells from her body.

Mayo Clinic Jacksonville
The vaccine reportedly removed cancer cells and showed evidence of the elimination of the tumour, as well as the activation of the immune system. Dr. Keith Knutson from the Mayo Clinic Jacksonville said that the results were what they had hoped for and that it was particularly significant as Mercker was their first human test subject. Following the success of the trial, Mercker underwent a double mastectomy to ensure that all cancerous cells were eliminated.
The success of the trial vaccine has sparked optimism among researchers at the Mayo Clinic, who are now working on several vaccines aimed at preventing and beating cancer. Dr. Knutson predicts that a trial will soon begin on a vaccine to prevent breast cancer in healthy patients, akin to a "flu shot against breast cancer".
