Seizures have numerous causes / triggers....
Saying people are doing this only after the vaccine is blatantly false and intended to further the spread of misinformation and pseudoscience.
I admit the first 3/4 look vaguely similar but I would need more information on when those events happened (time and date), where (city, state, country), the vax status of each person and if the person had a history of seizures beforehand......
Some people who have epileptic seizures do the same thing..... and epilepsy was around much longer than mRNA
