A scientist working on this topic should obviously not disregard anything like that. They should know how to interpret and filter such events.

I was speaking as and for random people on a technology internet forum where "$person got a vaccine on date ABC. $person got diagnosed with diabetes on data XYZ." has absolutely no merit discussing as causation or mental trigger that there might very well be "serious side effects" as stated by OP. I am sure many people died within minutes of receiving their shot because of simple statistics.

Also you went to paint a extreme example without any need. Please don't do that. No one died instantly, that's a huge over-exaggeration of what the linked paper is about. If you want to speak with analogies, maybe "1 person who bought this item also bought that item" versus "people who bought this item also bought that item" might be more suitable.
