would recommend titers to be drawn, too, if you have not had it done already.
For what it's worth, I just got mine yesterday, at 14w2d. I'm entirely convinced of the safety: http://www.ajog.org/article/S0002-9378(10)02286-6/abstract and http://www.ncbi.nlm.nih.gov/pubmed/23262941, just off the top of my Google Scholar.
'Course, what it's worth might not be that much! ;-)
I'm not worried about the miscarriage risk. I saw some huge study done in Europe (forget which country). I'd actually have felt better about getting it in the first trimester, but I was in the first trimester in the summer. I wonder about the neuro effects of getting it in the second trimester. The baby's brain is developing so fast right now, and it's just hard to know what does impact brain development, and it'll take longer to see the results among kids whose mothers were vaccinated at this stage. I feel like we have a better understanding of what impacts organ development in the first trimester. I know it's not entirely logical, but it just kind of makes me go "eh" and want to wait a little longer.
This recommendation just started within the last year, but yeah, it is recommended between week 27 and 36 now, to optimize transmission of pertussis antibodies to the baby.

Appreciate it. Its always interesting and useful to me, esp when debating this stuff in international forums, to get a sense of which countries do different things when. Like I say, unless its been introduced since my last child was born (nearly 6 years ago now!) we don't have it in the UK.
It has been awhile since I have been pregnant and I'm kinda out of the loop on pregnancy vaccines (risks, benefits, etc). I just remember having my titres done by the doctor. I had them drawn again for nursing school and saw that the rubella one did take that time, but varicella was weak. I had varicella as a kid (badly!) but somehow it was starting to wear off.
