This is true, but it is also in the “get struck by lightning while carrying a winning lottery ticket” levels of risk. Only a handful of healthy, young adults or children have died from Covid-19. Essentially all recover.
So yes, if you were a perfectly healthy 20 year old and completely selfish you might rationally conclude getting a vaccination was a waste of your time or even maybe not worth the risk of a rare side-effect (although I think side-effects are still less risk but both the risk of the vaccine and the risk of serious injury or death from Covid-19 are so vanishingly small it is not worth debating). However, you are part of society, and presumably have some older person or vulnerable person in your life you don’t want to risk killing. Maybe more transactionally, you likely participate in the economy or go to school and for that to work, everyone has be and feel safe interacting with other humans, including those at more risk.
The best way for this to go away quickly is for everyone, especially the young people with more personal interactions, to get vaccinated to reduce the rate of transmission. Some models say we should even vaccinate them first to have the largest/fastest impact on reducing the infection rates in the population. And the reality is that young people are suffering the most from the necessary restrictions (financial, mental health, etc.), and also share the same increased risk we all face when the health system is at capacity and unable to properly service non-Covid related health problems and accidents.
So, the logical conclusion is just get your vaccine and let’s get back to normal ASAP. Ignore the noise of the science and statistically challenged, and the selfish, and do your part to stop this outbreak.
