Did the Second Covid Shot Doom Rudy?

I did not know Rudy personally, but knew of him. His friends and family will greatly miss him. My understanding is this accident happened immediately after he got his second Covid shot. I'm wondering whether or not his reaction to the shot contributed to the accident in some way? How quickly do reactions set in after that second shot? Are they strong enough to impair a driver?

An 82-year-old Sacramento County man died Thursday morning after the pickup he was driving struck a guardrail and a sign pole along Interstate 80 in the North Highlands area, the California Highway Patrol reported.

Ellsworth Rudy, of Rio Linda, died in the crash along I-80 near Longview Drive, the Sacramento County Coroner’s Office reported Friday. 

Rudy was pronounced dead at the scene, the CHP North Sacramento Area Office announced in a news release. The crash was reported about 8:40 a.m. Thursday on the Longview exit ramp.
