How many women have breasts enlarged after being vaccinated with mRNA COVID-19 vaccine? The result of the inspection is surprising
How many women have breasts enlarged after receiving COVID-19 vaccine? Recently, a report on the side effects of a statistical vaccine in Norway caused concern. Many women said that they had a strange “side effect” after being vaccinated with BioNTech/Pfizer’s mRNA COVID-19 vaccine-their breasts became enlarged.
This is how it happened? Does the mRNA COVID-19 vaccine really make people’s breasts bigger?
This actually starts from the principle of mRNA vaccines. The two new mRNA vaccines currently on the market use the mRNA fragment of the new coronavirus encoding the spike protein (S protein), which is wrapped in a lipid nanoparticle (LNP) carrier. , And then injected into the human body, these mRNAs use the translation system of human cells to express antigen proteins, thereby activating the immune system, mainly by inducing B cells to produce neutralizing antibodies.
Lymph nodes contain B cells. These B cells produce antibodies and accumulate, leading to swelling of the lymph nodes. The swelling of the lymph nodes under the axilla on both sides pushes the breast forward and makes people feel that the breast is enlarged.
What is the proportion of such “side effects”?
We found a statistical report from the Centers for Disease Control and Prevention on the side effects in the clinical trial of Moderna’s mRNA COVID-19 vaccine. The statistical results show that after the first dose, 11.6% of people will have this kind of axillary lymphadenopathy. After the second dose, 16% of people will have this condition. And it tends to last for one to two weeks, and the proportion of young people appearing is higher.
In fact, as early as February 2021, researchers from the Department of Radiology of the Southwestern Medical Center in the United States published relevant case reports in the journal Radiology: Cardiothoracic Imaging, reporting three people (1 32-year-old male, 1 34-year-old female, A 39-year-old woman) developed a 1.4-2cm diameter axillary lymph node mass after receiving the mRNA COVID-19 vaccine.
A 34-year-old woman developed a 2 cm diameter lymph node mass after receiving the mRNA COVID-19 vaccine
This “side effect” means that the vaccine is working
Because lymph node enlargement is one of the early signs of cancer, some women, after receiving the mRNA vaccine, find that they have symptoms of swollen lymph nodes in the armpits, and worry that it is a precursor to breast cancer.
Regarding this concern, Christine Edmonds, professor of radiology at the University of Pennsylvania Hospital, said that although this side effect is annoying, it is usually harmless and will go away on its own. This side effect can even be regarded as a reassuring sign that the vaccine is playing its due role. She also said that there is no need to rush to contact the doctor if this side effect occurs. If the lymph nodes are still swollen and painful after four weeks, it is not too late to contact the doctor at this time.
This “side effect” also saves lives
It is worth mentioning that this side effect of the mRNA vaccine has also saved some lives. On June 23, 2021, the Des Moines Chronicle reported a case in which an American woman named Jennifer Moseley Two days after receiving the second dose of BioNTech/Pfizer’s mRNA Covid-19 vaccine, the vaccinated arm developed lymph node swelling. She didn’t pay much attention to it at the time. Two days later, there was still lymph node swelling and pain. At this time, she underwent a breast self-examination and it seemed that there was a swelling. So she hurriedly contacted the doctor for X-ray examination and biopsy, and the results confirmed that she had breast cancer.
It is understood that Jennifer Moseley has currently undergone bilateral mastectomy and breast reconstruction, and is now recovering. She said that it was the COVID-19 and the COVID-19 vaccine that saved her, otherwise she might have found breast cancer at an advanced stage.
In addition, recently, an article published in the top international medical journal JAMA showed that after inoculation with the COVID-19 mRNA vaccine, the concentration and vitality of male sperm increased
