Patient Experiences With the COVID-19 Vaccination After Breast Cancer Treatment

Study Overview
=================
Brief Summary
-----------------
This study aims to elicit patient experiences, choices, and side effects associated with the COVID-19 vaccine after breast cancer surgery. Lymph node swelling is a known and common side effect of both the Moderna and Pfizer COVID-19 vaccines. This is the body's normal reaction to the vaccine. It is worrisome that lymph node swelling after the vaccine mimics that found in breast cancer which has spread to the lymph nodes. This side effect will cause worry and anxiety amongst patients as a result. For patients who have had lymph node removal (axillary lymph node dissection or sentinel lymph node biopsy) and are at risk of lymphedema, the investigators are concerned that the lymph node swelling may tax the lymphatic system and incite lymphedema in those at risk or worsen it in those with BCRL. Fear of lymphedema is high in this population and the investigators need to better understand what risk, if any, lymph node swelling after the COVID-19 vaccine imparts to BCRL risk.

Detailed Description
-----------------
Hypothesis 1: Patients will choose to receive the vaccine on the arm contralateral to axillary lymph node removal, or in the lower extremity if they have had bilateral axillary lymph node removal Hypothesis 2: Patients with a history of breast cancer will experience axillary lymph node swelling after receiving the COVID-19 vaccine at the same rate as the general population Hypothesis 3: Patients with axillary surgery who develop lymph nodes swelling in the ipsilateral side might be at increased risk of developing lymphedema

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Vaccinated Breast Cancer Patients<br>Patients who enroll in the trial and decided to get the COVID-19 vaccine will complete surveys to indicate their experiences, side effects, location of vaccination (i.e. right arm, left arm, or leg). This information will be analyzed in conjunction with their breast cancer treatment history and lymphedema measurements. | Other: Survey<br>* Patients in all groups will complete surveys about their decision to receive or not to receive the COVID-19 vaccine. For those who did receive the vaccine, they will indicate their experience with the vaccination and any side effects they may have experienced.<br>|
| Unvaccinated Breast Cancer Patients<br>Patients who enroll in the trial and did not choose to receive the COVID-19 vaccine once it was available to them with complete a survey to indicate why they chose not to receive the vaccine. This information will be analyzed in conjunction with their breast cancer treatment history and lymphedema measurements. | Other: Survey<br>* Patients in all groups will complete surveys about their decision to receive or not to receive the COVID-19 vaccine. For those who did receive the vaccine, they will indicate their experience with the vaccination and any side effects they may have experienced.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| COVID-19 Vaccination on Contralateral Arm | The investigators expect 90% of participants to receive the COVID-19 vaccine on their contralateral (unaffected) arm. | 0 to 6 months | 
| Lymph Node Swelling after mRNA COVID-19 Vaccine | The investigators expect 10-15% of participants to experience lymph node swelling after receiving the Pfizer or Moderna vaccines. | 0 to 3 months |
