Effective Swedish HIV Vaccine

Unique Results from Swedish Study of HIV vaccine

A Swedish HIV vaccine study conducted by researchers at Karolinska Institutet (KI), Karolinska University Hospital and the Swedish Institute for Infectious Disease Control (SMI) has produced surprisingly good results. Over 90 per cent of the subjects in the phase 1 trials developed an immune response to HIV.

"Never has such a good result been seen with a vaccine of this type," says Professor Eric Sandström, Chief Physician at Karolinska University Hospital.

The trial subjects were vaccinated on three occasions with this vaccine using a needle-free method of injection. In order to enhance the effect, the researchers also gave the subjects a fourth dose of a vaccine in which parts of the HIV virus DNA had been integrated into another virus (vaccinia = the cowpox virus). This vaccine-based HIV vaccine is produced by the USA's National Institutes of Health and was donated for use in this Swedish study.

"Our vaccine is designed in such a way that it's able to protect against many of the circulating HIV types in Africa and the West," says Professor Britta Wahren at the SMI/KI.

Over 90 per cent of the trial subjects developed an immune response to HIV, and the vaccines have been tolerated well.
