Is it safe to get the flu and pneumonia shots at the same time or do they have to be given seprately? I am 6 months pregnant and have severe asthma.

Yes & no. "everyone" agrees that women who are pregnant during flu season should get attenuated flu shot (not nasal spray): http://www.Mayoclinic.Com/health/influenza/an00651. However, there's a bit more conflict re Pneumovax in pregnancy but it appears to be safe to lower risk of pneumonia: http://goo.Gl/uemcgp & http://goo.Gl/1k45v. Talk to your OB & family doc for their opinions. In general very safe.
Absolutely. I order them all the time. None of my patients have ever had a problem. I myself have had both at the same time. No problem. Good idea to protect yourself. Vaccinations protect you against disease, especially with asthma.
