Breast cancer surgery; This is a spontaneous report received from a non-contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A female patient received BNT162b2 (BNT162B2), in Sep2021 as dose 3 (booster), single (Batch/Lot number: unknown) for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Bnt162b2 (Dose 1), administration date: Jan2021, for Covid-19 immunization; Bnt162b2 (Dose 2, Her lung specialist removed a lung nodule in Mar2021 nodule that turned out be cancerous, Verbatim:removed a lung nodule), administration date: Feb2021, for Covid-19 immunization, reaction(s): "removed a lung nodule". The following information was reported: BREAST CANCER FEMALE (medically significant) with onset Nov2021, outcome "unknown", described as "Breast cancer surgery". The patient underwent the following laboratory tests and procedures: tested: (Oct2021) Cancer, notes: She gets tested again for cancer in Oct. Therapeutic measures were taken as a result of breast cancer female.  Clinical Course : Warm transfer from withheld. Caller on the line because she wants to know how long the covid 19 booster is good for. Her lung nodule was removed. She had breast cancer. These two surgeries were reported last Nov and one in Mar. Wanting to know how long will the fourth COVID-19 booster dose last?  She had breast surgery in Nov2021. She had her first covid 19 vaccine and second dose vaccine in Jan and Feb2021 and the booster in Sep2021. She had breast cancer surgery in Nov2021 and radiation therapy. Had the first and second set of initial vaccines and then her booster to get her through the surgery and the radiation. She had no reaction at all. She felt really protected while she was in the hospital. She was very careful not to get Covid. Pfizer vaccines pulled her through the surgery. Her lung specialist removed a lung nodule in Mar2021 nodule that turned out be cancerous, but it was very very early and then she was boosted for COVID-19because of that. That carried her for 6 months. She is in remission and is cancer free. She tries to stay out of crowds, be careful, stay away from sick people. She wants to get 4th booster because she has a wedding in Sep and really wants to go but wants to be careful. She wants to get boosted in the fall because in the fall and winter the spread gets really bad in her area and the tick has been going up already. She just called to see if the local government can get the mask mandate back. Her area is in the red zone. Everyone is coughing out in the public. No one is wearing a mask and the tick is so up. They are in cold weather still, but warm enough to go outside. Don't know if they will put that mask mandate back on. She is cancer free with a good prognosis, and gets the heard immunity thing, but because the hospitalization is down they aren't going to put the mask mandate back into effect. Pfizer has gotten her through the surgeries and within four days of the surgeries she was back on her feet and moving around. Because she was well vaccinated and didn't worry about COVID, it helped beating cancer. She thought they would put the mask mandate back and give the immunocompromised and elderly a break. The world got stupid. Our country just got stupid. No one wears a mask when she is out except for a few. She is wondering about the fourth booster. But she wants to time it right. She wants the Pfizer booster in particular. She was confident and had no reactions and was happy. She will double mask, but at least she is out and protected. She feels really comfortable with Pfizer. Has relatives that she won't let come near her until they are vaccinated. Manufactures aren't going to put out a bad vaccine and risk everything. Nothing is 100%. Nothing is guaranteed. We have to weigh our odds and protect ourselves. Her grandchildren are all vaccinated and boosted with Pfizer. The vaccine got her through a lot. She had to take her mask off for radiation because she couldn't breathe in the mask well and had to hold her breath during the radiation. It's one less thing she has to worry about and she commends Pfizer. Just wanted to know about how long the fourth booster will last. CDC doesn't have the information yet. Wants to know she can feel protected. She gets tested again for cancer in Oct, so she thought about getting the fourth booster in Sept. With the wedding being inside she wants the booster. Wanted to know if we have any information.   Declines report. She has learned after her breast surgery that she got overloaded and her family had to think for her. Then she realized that she just needs to answer what is asked of her. She just needs to answer the questions people have for her. Planned to get the vaccine before fall. The tick went up like crazy for fall and only at 67% are vaccinated in her area. The county isn't where it should be. They should be at 75%. Don't want to force people and municipalities and private business aren't mandating the vaccine. It only takes one person to get it and then you know everyone has it. Caller daughter tests herself before she comes around her.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
