His concern is that there could be long term side effects. You claim that if there were, they would already have shown up. Why do you think that? And why doesn't he accept your reasoning for that belief? You are wasting your time reading papers that don't find anything in my opinion. That wouldn't convince me. The things that I would have an issue with are: 1. Is there an effective treatment that's less risky than the vaccine (e.g. Ivermectin)? 2. Can we safely assume that adverse effects of the vaccines have been properly tracked and investigated since vaccinations began? 3. Is there any historical precedent for vaccine side effects becoming known after this time period (since Covid vaccinations began)? A rational person will get vaccinated if you can settle these questions in favor of the vaccines. Note, I'm assuming that the person takes the threat of getting covid seriously. There's a common misconception that everyone who doesn't want to get vaccinated thinks that it's all a big joke and covid is no worse than the flu. This is not true. Lots of vaccine-hesitant people take covid seriously.
