Thank you for making a good point. I'm saying we should use the limited data we have to make the best predictions we can until all of the data comes in. Of course, predictions don't always end up being right, weather forecasts being the obvious example, but there is still value in making them and trusting them (with a grain of salt).
Yes! And do not forget, the limited data includes the botched 1970s flu vaccine as well. Don't forget the infamous Tuskgee experiment. These are all valid data points that people can use to say "well i'm not going to be a guinea pig until the long term data comes out". There is also data that most people don't find out they are allergic until the first shot. That's anxiety inducing!
When you start becoming empathetic to the other side, you realize that there are gaps where simply hand waving doesn't make the problem go away. And this is a problem everyone with an opinion, on this topic, seems to forget
