Actually, a bit worse. The MMR vaccine (measles component notably) does not have a 100% response. Since in my facility we began testing for immunity I've come to agree with the ~90% response rate, at best. So, even with 100% coverage, only 90% (give or take) are going to be immune. If you take away allergies, and immunocomprimise, it doesn't take huge numbers of vaccine resfusers to drop below the 80% required for herd immunity. Thus, the outbreaks of measles in the UK, Canada, US and (ongoing) in Australia and NZ.

OTA is still the best way to get HD content. Most cable and satellite providers only go to 1080i. Fox Sports broadcasts in 720p, and yes, you can see a difference. And, most importantly, you get the full bitrate from Fox and CBS: the affiliates are not allowed to broadcast less that what the network provides. This in contrast to the cable and DBS providers, who are notorious "bit shavers". If you are lucky you can get away with an indoor antenna; I had to go really old school and place an antenna on my roof but the signals are great. Of course, some networks *cough*NBC*cough*cough insist on multicasting crap secondary channels which results in insufficient bandwidth and awful breakup with a fast moving picture.
