in mind because there are risks, benefits and tradeoffs. and the benefits outweigh the risks and we can do it safely and we have a vaccine that can be done even safer than last year when some schools opened safely. >> i know it will be tough politically, but should vaccines be mandated for kids older than 12? you can't go to elementary school or kindergarten unless you've had certain vaccinations? >> i favor the vaccination of children above the age of 12. whether or not they have the ability to mandate is a different question. do they have the rights that will set their conditions and the school can certainly add that to its vaccination list after measles, mumps, rubella and this is something that they could do in order to keep their school safe and less disruptive from covid. >> thank you very much. have a healthy, happy weekend. thank you for helping us sort through all of this.
