Discussing the current vaccines is of course of valid. The data does not yet exist to conclusively answer many important questions about their effectiveness particularly over time. Posting articles about the data and science are helpful. Posting articles that are devoid of useful information simply to sow doubt is worse than useless.

I also want to point out there there is conclusive data that older vaccines for many diseases, polio, small pox, etc, have saved many, many lives and yet people choose to believe that they are dangerous and refuse to inoculate themselves and their children. Pretty sure that is where the impetus to post these useless articles arises: to sow doubt about vaccines in general.
