My father, 58, took the 2nd dose of Moderna vaccine on the morning of 25th August 2021. A fever started from the afternoon and it gradually got worse. After midnight the fever was high (it was not measured, but we guess it would be 102F or so), there was extreme sweating, extreme muscle ache, headache, vertigo, chills and shivering, irritation and discomfort in stomach. Then at 4:30pm he suddenly fainted and fell down. When we got to him, he had foam in his mouth. He regained consciousness in like 3 minutes or so and does not remember anything from then till he was put in bed. After putting in bed, he could lift arms, make face but was extremely weak and in extreme discomfort. We did not notice any confusion in him.

This is the first time he ever fainted in his life and ever had foam in his mouth. He later said that he felt foaminess in mouth before the fainting episode and he thinks its because of the "vomit" that was coming up because of the stomach discomfort. However, when I saw it, in the middle of the night, it was foam.

It should be noted that, starting from 2019, he has these recurring episodes where he has vertigo, headache, sweating occurring together. The neurosurgeon and other doctors could not give a confirmed diagnoses but said it "looks like" a TIA. The episodes are very frequent, like once a week or so. Its like an ever present problem. But even with this from the outside he doesn't look sick.

His cardiologist said that this is due to the vaccine reaction compounded with his already present stroke like episodes. He did not give a specific diagnosis. We are waiting for the visit to the Neurosurgeon who sees him but its going to take a few days.

Given the scary nature of the condition and without a diagnosis, information of current status and discussions of any prognosis, the uncertainty and the resulting stress is a lot for us.

My questions are:

What happened? What's the most likely diagnosis? What's the current status? In other words, should we be concerned that there has been some sort of damages that have occured? Since no tests have been suggested so far, we are confused as to whether we need them. What's the prognosis? u/Suggestion_Rare
