couple thoughts:
1) the rota one was safety-Safety and Efficacy of a Pentavalent Human–Bovine (WC3) Reassortant Rotavirus Vaccine- it was a one year study link
http://content.nejm.org/cgi/content/abstract/354/1/23-- I haven't looked back at the full of the other two, not sure what they looked at
re:safety. found this same night I did those other ones.

| We randomised 1113 women between 15–25 years of age to receive three doses of either the vaccine formulated with AS04 adjuvant or placebo on a 0 month, 1 month, and 6 month schedule in North America and Brazil. Women were assessed for HPV infection by cervical cytology and self-obtained cervicovaginal samples for up to 27 months, and for vaccine safety and immunogenicity. |

This one looks at 2 months post dose 1, which is more than 6 weeks:

This one looks at safety and efficacy for 12 weeks post PCV:

Some of these I have not read completely just throwing out anything I see in my folders of more than 6 weeks.
Not sure what this exercise is for though...which leads me to this:
2) I am not sure how else they can do this because as you get further from the vaccine you aren't going to have accurate results as well as exponentially rising things to control for. We have many studies that look retrospectively and some that look at things like diabetes and hib and autoimmune disease and Hep B vaccine which tend to be more than 6 weeks. If they are looking for one thing, I assume it is easier. you look at the groups and see if one group is higher than the other.
but also, since they serial list anything that happens in the study period-- which is the subject of this thread-- if you have study that looks at doses at 2, 4, 6 months and then 12 and 18 months like DTaP or something, you are getting surveillance from 2-18 months and all of the things that happen are gonna be in that laundry list, including car accidents and teething apparently!
sorry this post is probably not put together very well but I am off and I will be back sometime next week!
