Answer:
Previous generations have worked hard to get science, technology, and medicine to where it is now; and because of that, the youth of the next generation have higher chances of survival. As time goes on, new diseases emerge and that is why each generation has to race with nature to find a solution. The vaccine is one of those important solutions as without it, the emerging diseases will continue to spread and mutate into stronger variants (eg. Covid-19 now has Delta and Omicron variants). To not forsake their efforts, the next generation should be open to using what the previous generations have developed. The development of vaccines was no easy task, numerous scientist had to undergo a lot of trial and error for it to be safe; vaccines aren't only made from novel research, it was also from years and years of experience.
