I'm not really concerned about increase in whooping cough. Big portion of these 'news' are made up or exagerated. It might be 80% true, or not true at all, don't know if I should believe it.
We have a few fine holistic doctors in the area that I used and trust, so I'm not as worried as I might be if I was in rural area. Will worry if a problem arrives, I'm not going to introduce problems through vaccines. Besides, vaccines don't eliminate the risk of disease anyway, so what's the benefit?
I wouldn't try claiming religious exemption from some vaccines but not others, it complicates things. I think it's very risky, you may end up having to do ALL vaccines.
