Patient received the second dose 12Feb2021. At first they did not think it was all connected until told family of nurses who were familiar with the reaction. They were familiar with this and heard of others who have had this same reaction. They mentioned they have heard it occurred 4-5 times, one being a nurse after getting the covid-19 vaccine. They told caller to report this to UAB. She tried to report to UAB, but they did not seem worried about it. She was calling us because she thought someone should know about it. She thought if more than one person had this reaction most likely a side effect and should be aware. Reporter further explained her husband had severe shaking (it was with his nervous system) so much lasted about 4-5 hours at a severe state. Then it got better, but it took close to 3-4 days for it to completely go away. However, after the shaking so much episodes her husband was extremely weak after that. He still has not gained his strength back. However, now at this time he is now 83 years old and they are taking that into consideration as well. He also had diarrhoea, It began within ten minutes after the shaking started. It stopped within three days. Her husband was shaking so much he was unable to stand or walk. It also made him weak. They had no idea what it was. It went away as fast it came. It was not lasting. Patient also had a rash on the back which was something that had never occurred before. She clarified it started within a week of the second shot. She further added, it was all happening at the same time. Unable to clarify statement further. At end of call, caller added she did not know if anyone kept a record of events such as this. Stated maybe it's connected. Stated she knows people are allergic to things. The outcome of the event diarrhoea was recovered on an unspecified date in 2021 and rest of the events was unknown.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
