What does this quote mean? It’s been driving me crazy and wasn’t sure where to post it lol I’ve been seeing it so much.

My mother-in-law died of heart issues after receiving the jab, my sister has shortness of breath when exercising, worse after the jab and my cousin was sick over a minor cold for weeks recently. I don't know if all these are jab related or not, we'll never know in each individual case because there is no way to have a controlled study, but it is coincidental that they all took the jab. People that did get vaccinated also have a vested interest in believing that it is safe, so they won't make the connection that any abnormal illnesses they are experiencing are attributed to the jab and they won't be forthcoming and honest about any strange symptoms they're experiencing. This whole debacle has been a goat screw.
