One of the newest DNA vaccine delivery methods relies on technology known as the “gene gun,” which is capable of delivering the vaccine directly into cells. The needle-free vaccination method is more cost-effective and less painful for the recipient.
“The DNA is first coated onto very, very tiny gold beads, and those gold beads with the DNA are then put inside of a plastic device that's about the size of a small flashlight,” she explained. “Inside that device is also a little canister of compressed helium gas. When the trigger of the gene gun device is pushed, the gas is released and it propels the gold coated with the DNA out of the device into the skin of the vaccine recipient.”
A 60-year-old Toronto man with swine flu and congestive heart failure has died.
This is the second death of someone in the city with the H1N1 flu virus and the third in Canada.
The man had been on life support at Toronto Western Hospital, part of the University Health Network.
Andrew Morrison, a spokesperson with the Ontario Ministry of Health, says it's not known whether the virus was a factor in the man's death.
On May 23, a 44-year-old Scarborough man who had the virus died. An autopsy failed to show whether the virus contributed to the death of the man, who also had diabetes and significant heart disease.
In April, a 39-year-old northern Alberta woman with H1N1 and a chronic, pre-existing medical condition died April 28. A post-mortem failed to show whether the virus played a role in her death.
To date, there have been 715 confirmed cases of the H1N1 in Ontario. The virus is presented very much like regular seasonal flu, which kills or contributes to the death of some 4000 Canadians annually.
TORONTO — Chalk up another species for the wily flu virus.
Researchers in Tennessee are reporting they diagnosed an outbreak of influenza in giant anteaters in the Nashville Zoo. The outbreak, which took place in March 2007, involved infection with a human influenza A virus, of the H1N1 subtype. It's believed the outbreak in the 11 adult anteaters was triggered by a caregiver who was working while sick with a respiratory infection.
It's not clear if the caregiver infected all the animals or if there was some anteater-to-anteater spread of the virus, but all the animals survived.
The researchers say viruses isolated from nasal swabs taken from the animals were virtually identical to the human H1N1 viruses that were circulating in Tennessee at the time.
The research appears in the July issue of the journal Emerging Infectious Diseases.

Dr. Paul Offit of the Children's Hospital of Philadelphia (CHOP) received at least $29 million from his share of royalties for Merck's Rotateq vaccine after using his position with the Centers for Disease Control and Prevention to ensure that childhood vaccination with the vaccine became compulsory.
The WHO is working on revamping its six-point pandemic scale so that the top alert reflects the severity of the flu and not just the geographical pattern of its spread.
Fukuda said one idea was to add a three-point severity scale within the highest marker, so that the overall level could reach 6 even if the flu's symptoms remained moderate, and it could be adjusted later if it had more serious effects.
"It is not enough just to say we are at a certain phase and that a virus has spread to a certain extent. That kind of announcement really has to be accompanied by some indication of what is the severity, and some guidance to countries on how they can modify their approaches to what is going on.."...
An Ontario man hospitalized for other ailments has become Canada's third victim of swine flu, health authorities said Tuesday.
The man, who was previously diagnosed with the H1N1 flu virus and had been hospitalized for several weeks, died on Sunday, Ontario health ministry spokesman Andrew Morrison.
"He did have a number of underlying medical conditions, so we're not sure how the flu contributed to his death," he told AFP.
A Toronto man and a woman in western Alberta -- both with chronic diseases -- were the first to die of swine flu complications in the last two months.
On Monday, Canadian health authorities reported 194 new cases of the A(H1N1) virus, including four in the far north, bringing the total number of people with the virus in this country to 1,530, including 57 who are hospitalized.
Scientists around the world are accelerating their efforts to develop a vaccine against the H1N1 influenza virus (Swine flu) as rapidly as possible, reports Genetic Engineering & Biotechnology News (GEN). The need for such a vaccine received a strong impetus from the World Health Organization, which has issued a Phase 5 pandemic alert, a strong signal that the WHO believes a pandemic is imminent, according to the June 1 issue of GEN.
Canadian health officials in Manitoba Tuesday were investigating whether an outbreak of respiratory illnesses on an isolated Indian reservation is H1N1 flu.
