I do not. Even though the pharmacy says you can, I told the nurse I rather get them a few weeks apart and she agreed with me. In the unlikely event you have a reaction, seems like having them separate would make it easier to investigate what the issue was. I think the pharmacy suggests getting both together since they think people might not bother to return for the second one after having the first.
Everyone's system is probably different and never had a reaction to either of them (other than a sore arm), but some of my relatives feel ill for a day or two after getting them.
