spit up a slime which was a yellow color/spit up another blob of slime; cough; burning in the back of my throat; burning all the way down my esophagus; This is a spontaneous report from a contactable consumer (patient). A patient of unspecified age (Age: 74; Unit: Unknown) and gender received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), via an unspecified route of administration in left arm on 10Jan2021 at single dose for COVID-19 immunization. Medical history included cold and extremely ill from 1981 to an unknown date. The patient's concomitant medications were not reported. The patient stated, "I was reading the fact sheet that was given to me after I received my Vaccine on the 10Jan2021 and I developed a strange thing which was the cough. I don't cough. I never had a cold since 1981 that is not being exaggerated that is the truth because I was extremely ill. So I know it was 1981. About 6 hours after I came home from getting the injection. I do not know, there was the burning in the back of my throat. So I gargled some salt water but it did not go away. By the evening I had a horrible cough and burning all the way down my esophagus and I was coughing. I don't cough it's not that. I am well, my lungs are well I never cough. Next morning again I was coughing. If I sat still and didn't move it stopped and then it would started again when I get up and move around. The coughing was like a raspy cough that was strange. I have never experienced anything like it. However, on the morning of the 13th of Jan2021, 3 days after the injection I began to spit up a slime which was a yellow color. Now I don't do that, it is not a part of my healthcare, my lungs are fine, I have never smoked, not one sign of lung problems ever. So I spit up the big thing of this slime. The next morning which was yesterday, I spit up another blob of slime and today the cough is gone like I never had it. Now I know this is not the normal for me, this has never happened to me before and so it is either a coincidence. I had the injection which I requested and the symptoms began slowly in the evening after I got the injection on the 10Jan and stopped last night, it just stopped, the last bit of slime came out of mouth, out of my lungs and the coughing stuff and that what happened. I don't know what that is but I have a feeling that the two are related in some manner. I am not a sickly person, I had nothing going on in my body, I am very lucky, I am 74 and I had nothing. So this was surprise and shock. This may be an interest to your survey. I have been in this house for eleven months. I have not left. I have had food brought to me and I have had medicines (Unspecified Medications) brought to me and no one has come into my home since eleven months. So if I have somehow contracted this virus. God only knows because this little known and no one comes in my home and I am isolated for 11 months. That is how hard I have trying not to get the virus. I have not, have I been taking medication and been to a doctor no, I have not. I have just been in my house."
