Question: Do live vaccines such as that used for smallpox can activate a dormant infection such as HIV!?
therefore do live vaccines have the ability to cause dormant viruses to become virulent!? Www@Answer-Health@Com
Answers:
No!.
But there are a couple of notes worth mentioning!.
Live vaccines, as the name suggest, are LIVE viruses or bacteria - so that they have the capability of causing real infections in the host!. Sure, these vaccine strains of germs are engineered to be safe, but rarely problems do happen!. For example, the Yellow Fever vaccine to date has caused 7 cases of fatal encephalitis -- but that's not too bad, noting that as of a few years ago, more than 308 million doses had been used!.
My point - there are risks present in live vaccines that do not exist with killed (inactivated) vaccines!. As a result, we take special care NOT to give live vaccines to AIDS patients, nor to pregnant women, cancer chemotherapy patients, and recipients of organ transplants who are immune suppressed!.
Although you might give a live vaccine to someone with HIV who was asymptomatic and had a very high CD4 count (> 500/mm3), you'd do it a bit cautiously!. You would not give live vaccines to those with AIDS!.
One other note -- ANY vaccine (live or inactivated) will cause the HIV viral load to temporarily rise, and the CD4 count to fall -- this is just a temporary phenomenon that lasts 2 or 3 weeks!. It is NOT dangerous nor clinically important at all, except for this:
you do not want to get your HIV viral load and CD4 count checked within a month of getting any vaccine -- just because your numbers will be artificially altered by the receipt of a vaccine!. Instead, be sure to get your vaccines right AFTER you've had your bloodwork for HIV checked (which is usually done every 3 to 4 months)!.Www@Answer-Health@Com
