You found flaws in a scientific peer reviewed study?....uhhh, ok

Things aren't perfect simply because they're peer reviewed.
First, the article you cited has several mischaracterizations of the research which I will discuss below.

After six months, the tai chi group had nearly twice the level of immunity against shingles than the education group.

This is false. The rate of increase was nearly double for the TCC group than for the education group.

False. Vaccine alone produced a change of about 15%.
Other notes. The analyses seemed to use a lot of
t-tests, rather than an overall ANOVA. For independent measures, this inflates the Type I error rate (the probability of seeing something that wasn't there). Further, and for whatever reason, the reporting format of the tests is off of APA standards (no t values or degrees of freedom?). This isn't critical, but it certainly is odd. Finally, the researchers themselves acknowledge several limitations to their study, such as the fact that there was a ceiling effect before vaccination (can't make reliable inferences based on post vaccination scores).
