Clinical narrative: swollen lymph node on her left collar bone; This is a follow up spontaneous report from a contactable consumer. This female consumer(patient) reported.  A female patient of an unspecified age received BNT162B2 (PFIZER-BIONTECH COVID-19 mRNA VACCINE; formulation: Solution for injection, Lot number and Expiry date was not reported), via an unspecified route of administration on 01Jun2021 as dose 1, single for covid-19 immunisation. The patient medical history was not reported. The patient concomitant medications were not reported. On 11Jun2021, 10 days after the first dose she noticed a swollen lymph node on her left collar bone which is the side that she had the injection on. She stated that it was the side of a hard marble and she could easily feel it and know that it was there. It has since gone down to the size of a pea. The patient stated that she read about this side effects from the CDC and from what I can tell it is a rare side effects but that most of the time it is harmless. When she first noticed it she couldn't get in with my regular doctor until August, so she went to the urgent care. They were a little too concerned about it she think but she like being too concerned rather than not. They recommended an X-ray, ultrasound, and referral to an ENT. The patient had the X-ray there that day and she had not heard back so she assumed that means that it was fine. She got in to see my regular doctor a few days later and they didn't seem as concerned with it. They said that this can happen with the vaccine and that if it didn't go away or if it had gotten bigger then they would do a referral to an ENT at that point. They did blood work and it came back fine. She called where she got the vaccine and told them what happened and that she was waiting on blood work and asked if she should still get the second dose. They told her not to get the second dose right now and that she could wait up to 6 weeks or 42 days from the first shot to get the second dose and that these were recommendations from the CDC. It will be 6 weeks from the first dose next Tuesday. She would like to know if this side effect of the swollen lymph node has been seen or reported and if you have anymore information about those reports. She got her first vaccine on 01Jun2021 and around 10 days later she got a swollen lymph node on her left collar bone. It was on the same arm as the side that got the vaccine. She read that lymph node swelling can happen and are harmless and rare with the Pfizer Covid-19 Vaccine. She went to the doctor because she was concerned and they were not sure because they did not know if she should get the second shot or not. She ended up with blood work done which was all fine. She delayed the second shot because she called with held and they said and informed her that people can wait 6 weeks between dosages. The reporter wanted to know if this is the most up to date time frame since it was 3 weeks. The lymph node is still there, minimized, and she wants to know if it is completely harmless or should she wait until it completely goes away. She read online that usually lymph nodes last for 10 days and if not contact a doctor but it has been over 2 weeks. She confirmed that she got Pfizer's number through VSAFE but wanted to report online to Pfizer. She got her first vaccine 01Jun2021 and cancelled the second one because she was waiting for bloodwork still. She asked and they said she has 6 weeks to get it. The outcome of the event was recovering.  Information on lot/batch number has been requested.
