Very sorry to hear about the person you know with Bell's Palsy, I wish them well and with some luck hopefully they'll recover from it and get back to normal.

However, there is not yet any evidence I've seen that the vaccine can cause Bell's Palsy. There's not conclusive evidence it can't, but the FDA says: "The observed frequency of reported Bell’s palsy in the vaccine group is consistent with the expected background rate in the general population."

(Please do correct me if I'm out of date and there's anything showing statistical significance, but I don't see anything new from a quick Google.)

When you vaccinate a lot of people, some of them will develop medical problems that would have developed regardless of the vaccine. It's not impossible you will be proven right once there is more data, but until then it is spreading misinformation to say that the vaccine did cause the problem.
