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.

A vaccine developed by SMI scientists has now undergone the first clinical study on healthy individuals in Sweden in order to examine its safety and different methods of administration. The vaccine is what is known as a genetic vaccine, which uses parts of the virus DNA to stimulate the rapid endogenous production of the proteins for which the injected DNA codes.

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.

Data from the study will be presented at the four-day HIV vaccine conference in Amsterdam starting 29 August under the heading “Multigene, multiclade HIV-1 plasmid DNA prime and MVA boost is safe and highly immunogenic in healthy human volunteers”.

Scientists now hope to follow up the Swedish study with a larger phase 1 – phase 2 study in Tanzania, planned to commence this autumn, in order to corroborate the Swedish results on African subjects and to help train Tanzanians to carry out parts of the study, including sophisticated laboratory examinations, on site.

The project is being led by KI professors Gunnel Biberfeld and Britta Wahren at the SMI and Eric Sandström at Karolinska University Hospital.

SMI has been running major projects in the HIV field since 1986 with the support of Sida/SAREC, the EU’s 5th Framework Programme, the Swedish Research Council, Karolinska Institutet, and Karolinska University Hospital. Over the past few years, the projects have tended more and more towards developing a vaccine for the prevention of HIV.

Data from the study will be released at the conference presentation on 30 August.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
