have another clot; does not feel up to par; gets tired/a lot of fatigue; has no energy/run down and weak/weaker; lightheaded at times; congestion; coughing up chunks of slime with some blood in it; can't mow the whole lawn like I was able to do, can't get out of bed some days and that's just not me; a little more headachy; not eating as much sometimes; pain and stiffness in my neck and shoulders; pain and stiffness in my neck and shoulders; cant move my neck because it hurts; This is a spontaneous report from a contactable consumer (patient). A female patient of an unspecified age received BNT162b2 (PFIZER BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Lot number- unknown) via an unspecified route of administration on an unspecified date in 2021 as dose 2 single for COVID-19 immunization. Medical history included blood clots in my lungs (I have a history of blood clots in my lungs and I'm on blood thinner to prevent getting anymore). Concomitant medications were not reported. Historical vaccine included BNT162b2 (PFIZER BIONTECH COVID-19 mRNA VACCINE, Solution for injection, Lot number- unknown) via an unspecified route of administration on an unspecified date in 2021 as dose 1 single for COVID-19 immunization. Patient stated that she received the Pfizer COVID 19 vaccines in late Feb2021 and early Mar2021. She reported that she had been having symptoms since having the vaccines that she did not have before. She stated that on an unspecified date in 2021, she does not feel up to par, gets tired faster, has no energy, lightheaded at times, a lot of fatigue, congestion, coughing up chunks of slime with some blood in it, can't mow the whole lawn like I was able to do, can't get out of bed some days and that's just not me, wanted to do the bushes today but I didn't feel up to it, last night I was a little lightheaded and a little more headachy. I've just never felt so run down and weak. It may be from not eating as much sometimes but I'm not sure. I have also had pain and stiffness in my neck and shoulders that I didn't have before and that started about a month ago. Sometimes I wake up or do something and I cant move my neck because it hurts. I bought a heating pad and maybe that will help. I went to the doctor in May and I didn't tell them about this because it hadn't been going on that long. They did blood work and said that everything was fine except my B was a little low on an unspecified date in May2021. At that point COVID was still bad to I was wearing a mask and being really careful when going to the store or the doctors. When I was coughing up a little blood I thought I might have another clot but the doctor said if I did then my legs would swell up. The coughing up stuff with a little blood in it has stopped thankfully. She stated that other people have had this same reaction, especially young girls. I had also spoken with other people about their side effects and it seems that people who were healthy are having side effects after the second shot that last a long time. She stated that with the first shot everyone was fine. She reported that she knows a girl who was in her late 20s early 30s who has had fatigue since the shots. Another girls sister has had headaches since the second shot and she didn't have headaches before. I just think its odd that people are getting symptoms so young. Patient had heard a lot about the (company name) vaccine causing people to have blood clots. One of my friends said that we did not know what's in the vaccine and it could be anything. I know some people got that 24 hour chill and flu symptoms but I did not get that after the shot. Some people did not want to get it at all because of the symptoms. People who never have symptoms all the sudden have all these problems. I'm kind of concerned and upset. If I go to my doctor they're not going to know what to so about these symptoms because they don't know about the shots. That's why I was calling you. I pray that they were not going to make people get a third shot because if peoples bodies were reacting like this after the second shot and they want to give them a third then. she never had that before the second COVID vaccine. The outcome of the event coughing up chunks of slime with some blood in it was recovered on an unspecified date in 2021 and outcome of the other events was unknown.  Description of complaint: Caller was reporting AEs after the Pfizer COVID vaccine and mentioned that she wants to find out more information because some people are scared because they don't know what's in it. Caller also is requesting for information on the COVID vaccine like if it is secure and safe.    No follow-up attempts are possible; information about lot/batch number cannot be obtained.
