The scientific community has been promoting the importance of vaccinations for centuries. CENTURIES. Seriously. Benjamin Franklin wrote in his 1790 autobiography that he regretted not inoculating his son against smallpox back in 1736. That was 279 years ago. So it's no surprise that this timely Star Wars public service announcement about immunizing your kids against measles, polio, and whooping cough came out all the way back in 1978.
Immunize your children and not just against childhood diseases. Take your tweens to the clinic to be vaccinated against the human papillomavirus (HPV). If you have any reservations about this because HPV is a sexually transmitted disease, GET THE HELL OVER IT. A dear, dear friend of mine contracted the virus, just like 50% of the sexually active population will at some time. Recently, it quickly progressed into Stage III cervical cancer. Because she and her doctors were closely monitoring the virus, they were able to treat it before it got any worse. And, from the research I read when I heard the news, it could have gotten a whole lot worse.
Immunizing your children is an investment in their future. Do it for them. Do it for herd immunity. Do it for Artoo.
