Vaccinations with a Pregnant Kitty

I have a question. I took in 3 female kittens about 6 months ago. They have all been inside the whole time I have had them. They have all gone into heat in the past month. So, I wanted to take them to get updated on their shots so that I could have them fixed.

Well, about 2 weeks ago my husband didn't shut the front door all the way and they all got out....I found all but one right away and the last one was out for a good full day and night. I think that one might be pregnant but it is too early to tell.

I am concerned because I took the other 2 kittens yesterday and got them started on their shots. They recieved FVRCP and Pyrantel. I didn't take Eleanor because I was worried that if she is pregnant then the shots would harm the unborn kittens and from what I have read I am glad that I didn't.

My question now is, I have seen some things online about how you shouldn't vaccinate ANY of the cats in the house when one is pregnant. Is this something that I should worry about and try to keep her away from the others?

I don't see how it would be a problem if the others were vaccinated.

Is there a reason that you want a kitten to have kittens when there are enough kittens and cats in shelters already?
Her age can cause potential problems with her pregnancy. IMO get her spay ASAP - this week. Not next week, not two weeks from now, and not after she potentially has more kittens - this week.

You can take a pregnant cat in to get spayed if the cat is too young to safely give birth. If they're still kittens under 1 year, it is dangerous for her to attempt to give birth at that age.
