Thanks a lot for your well-thought and compelling comment too. Although Big Pharma is profit-driven, I'd like to think that they have saved countless lives. Without mass production of antimicrobial drugs and vaccines, pathogenic microbes might still be humankind's top killer.
While it's unfortunate that vaccine blunders exist and have taken lives, I don't really expect perfect solutions to every problem. But some solutions (with its limitations and risks) may be better than no solutions, I think.
The vaccines are still winning for now, if I'm not wrong, although they are getting less and less effective. Those problematic variants all arise in the unvaccinated population, so the argument can also go to the importance of vaccines in stopping SARS-CoV-2 evolution.
You raised a valid point in that vaccines will most likely not make much of a difference in Covid-19 deaths in the young. While that is true, I'd like to think that the vaccines can help reduce risks of the chronic long-covid syndrome or other long-term health effects of Covid-19 (e.g., increased risks of heart and lung diseases in the future). You can read more about this here:
Ultimately, I think getting the vaccine for young people may boil down to a personal choice, in light of the risks and benefits of doing so. As you have mentioned, waiting until one gets older to get the vaccine is also a wise choice, in case any long-term health effects of the vaccine get discovered.
