Flu Vaccine and Viral Load

Jan 10, 2001

I found out I was HIV+ in 1989, but I didn't start antiviral therapy until January 2000. At that time my CD4 was 150 and viral load was 300,000+.

In October 2000, my viral load was at 62. In November 2000, my viral load was at 66. My CD4 counts have steadily increased all last year. My viral laod has never been below 50 despite taking Viracept and Combivir for nearly a year.

After my November blood draw, I got a flu shot. At my December blood draw, my CD4s had increased to 415 from 400 and 15%, but my viral load jumped up to 2200. Could the flu shot temporarily increased my viral load? Is it a good sign that my CD4s are increasing? My next blood draw is Jan. 15.

My concern is that I'm on a drug study, and if the viral load doesn't drop below 2000, I'll be disqualified from the study. My health insurance will only pay for about 3 months of Viracept and Combivir.

Thanks for your help.

Response from Dr. Holodniy

A flu shot can indeed result in an increased viral load. This has most commonly been reported in people on no HIV treatment, or in those on treatment with detectable viral loads. It usually does not affect viral loads that are undetectable. Elevations after immunizations can range from anywhere from 2-100 fold. The viral load usually falls back to baseline within one month.
