The MMR vaccine doesn’t even cause seizures!

“The MMR vaccine has been associated with a very small risk of febrile seizure as a side effect. Two recent studies indicate that for every 10,000 children who get the MMR and varicella vaccines for their first vaccinations when they are 12–23 months old, about 4 will have a febrile seizure during the 5–12 days following vaccination.”

It can cause febrile seizures, but even then, it is only at about a rate of 1 in 2500 children after the first dose (0.04%).

Is that “five times the rate from the actual measles infection?”

As I’m sure you are guessing, the answer is obviously no.

Overall, seizures occur in about 0.6% to 0.7% of measles cases!

In addition, actual measles infections can cause non-febrile seizures, which are much more serious than febrile seizures.

Also, measles can cause encephalitis, a life-threatening complication that is often accompanied by seizures.

This is in contrast to simple febrile seizures, which again, are typically considered to be harmless.
