Colds and flu

I and my daughter and family all got sick in succession. Then I started to feel better and decided to get the vaccine. Shortly after, a few days I became seriously ill/ ended up several weeks later after I wasn't getting better going to my PC who decided that I needed azithromycin. I do have some pretty serious asthma and I live in a very polluted area. Getting better slowly, at least I can breathe now, but if I venture out to do anything the sore throat comes back and I feel weak again.I see my Dr. again in the morning as I have had pneumonia before and he is very leary about that.
