Well, we have seen several flu epidemics which caused a global panic, but if we set those aside, influenza kills around 290,000-650,000 people annually. So far, COVID-19 has killed 4.48 million people, and it's only emerged to the scene in late 2019. This is only the number of deaths, even more people have suffered other grievous consequences from the virus - it can cause long-lasting or even permanent damage. The stakes are orders of magnitude higher, so social pressure is obviously going to match that. Again, a young person has very little to worry about as far as their personal health is concerned. Over 80% of COVID-19 deaths on record in the U.S. are 65-and-over, and mortality is fairly high, relatively speaking. Their immune systems are just not in the best of shape, even if they are vaccinated, so it's up to us to ensure that they don't get sick, if we can help it. Again, no pressure - as far as I'm concerned you can do what you want. It's simply prudent to get vaccinated, and global data indicates that the jab is safe. Ultimately this is a question of whether you care to chip in on the effort or if you hold the belief that people at risk should simply get the jab themselves. The latter position is flawed in the sense that the jab is, again, not a force field - it boosts your immune system, it does not grant you complete immunity from the virus, which may or may not be good enough depending on how effective your immune system is. If a patient is advanced in age, the answer to that question is "not very effective", there's a reason why the elderly statistically tend to be sickly. I'd reconsider your decision if I were you, but what you do is none of my business - I can only offer explanations and recommendations, I'm not your dad.
