A modified virus encoding an anti-AIDS antibody can protect animals from HIV infection.

Very interesting application of gene therapy. 

Was the experimental group also tested with an HIV PCR?  Or other HIV antibodies?

Certainly there will need to be tests for long-term efficacy with multiple exposures to the virus.

If a vaccine can be developed, perhaps the disease can be eliminated in the next few decades.

I wonder if a similar method could be developed against Plasmodium Falciparum.  In some areas, the two vaccines could be delivered together.

AIDs vaccines of many types has been actively pursued for a good while with little to any success. Some attribute this to lack of fcus - moneys are spread unproductively - alot of money but heavily diluted among concepts and substantial bureaucracy.

Indeed very interesting.
I guess this sc-AAV 8 vector could be developed as a platform for vaccines against a wide range of diseases.

I foresee a great future for human-virus interaction, going from diseases to treatments

I disagree.
Perhaps more funding would help, but HIV/AIDS is one tough disease to fight.  And, over the last few decades there have been tremendous strides forward in the treatment.

There actually is a viable vaccine.  However, the vaccine is only 31% effective. (http://www.time.com/time/health/article/0,8599,1925957,00.html).  Very statistically significant.  Yet, not the same efficacy as what people get used to with other vaccines.  Imagine the benefit in countries where 1/4 of the population is infected with HIV, if one could reduce the new infection rate by 1/3.

Anyway, putting all of one's eggs in one basket is not wise.

Creating viruses that make our own antibodies is a very novel approach to vaccination, and might never have been tried if all the funding was held by a lab that was trying a more traditional approach to vaccine development.

If we have one chance to wipe out this killer disease.  Perhaps we should wait to distribute any vaccine until we can make a multi-vaccine cocktail, just like the multi-drug regimens that are being used to treat the disease.  And, then have required booster-shots for high risk individuals.
