Researchers said last month that the vaccine lowered the risk of infection by about 31% — a “modest benefit,” they said, but one that was statistically significant, suggesting the finding was not a fluke. Another slice of the data that was not released at the time — one that looked only at patients who received all of their shots as scheduled and had the full sequence of shots before becoming infected — suggested the vaccine was 26% effective, the WSJ reported this weekend. But that benefit was not statistically significant: There was a 16% chance that benefit may have been a fluke, and the cutoff for statist...

Put another way: The results aren’t particularly strong, as far as vaccines go — the vaccine combination used in the study won’t be able to stop the spread of HIV around the globe. But, given the history of AIDS vaccine failures, any benefit at all is something worth noting. Over the course of three years, 74 of 8,198 people who received placebo shots became infected with HIV, compared with 51 of 8,197 people who received vaccine. So the vaccine appeared to reduce the risk of being infected by 31%. The statement from NIH, one of the sponsors of the trial, called this a “modest preventive effect.” Patients who re...

It was a business trip: Some luminaries in HIV-vaccine research were gathered there to open a new lab. The center, a research hub for the International Aids Vaccine Initiative, is something of a big deal for New York City, which has lots of fancy researchers and academic hospitals but has long been a biotech also-ran. As the New York Times recently noted, the city hopes a little biotech hub will spring up in the Army Terminal, a giant hulk of a building commissioned in 1918 and designed by the famous architect Cass Gilbert. Over three million troops (including Elvis Presley) passed through the building during WWII. The mayor was on hand yesterday to wave the flag, but we wer...

Maybe he was just offering a salve to all the bruised spirits here in Mexico City, but his talk marked a change in the often discouraged tone of the NIH’s...

The vaccine, created by an NIH researcher, uses a cold virus as part of its delivery mechanism. The same virus was implicated in the failure of Merck’s vaccine — which may actually have made some people more susceptible to infection by HIV, the virus that causes AIDS. Anthony Fauci, the NIH official who made the call to cancel the study, cited that issue as one reason for canceling the study, which was originally slated to include 8,500 people and cost about $140 million. In a sign of tough times for AIDS vaccine development, even those wholly dedicated to the devel...

Dennis Burton (pictured) wasn’t among them. “Six or seven years ago, I decided that this was what I would be doing the rest of my life,” Burton, an immunologist at the Scripps Research Institute, says in this Bloomberg profile. For more than 20 years, researchers have been trying to create an AIDS vaccine. But HIV, the virus that causes the disease, cloaks itself in copies of human molecules after invading a human host. That makes it very, very hard for a vaccine to do its essential work of training the body’s immune system to recognize and attack HIV cel...

The vaccine, created by the NIH, may be studied in about only 2,000 people in the US and Africa, rather than 8,500 as had been planned. The International AIDS Vaccine Initiative, which helped bring six vaccines to human testing, will announce today it has pulled out of the trial. Support has dropped for studies of existing experimental AIDS vaccines since September, when Merck announced its shot may have made people more vulnerable to infection. AIDS researchers say concern was further heightened after a second test of Merck’s product, conducted in South Africa, also found t...

The results of the trials, which enrolled volunteers on four continents, have spurred intense scientific inquiry and unprecedented soul-searching as researchers try to make sense of what happened and assess whether they should have seen it coming. Both field tests were halted last September, and seven other trials of similarly designed AIDS vaccines have either been stopped or put off indefinitely. Some may be modified and others canceled outright, the paper reports. Numerous experts are now questioning both the scientific premises and th...

Merkel cell carcinoma mostly afflicts the elderly and people with weaker immune systems, including AIDS and transplant patients. The newly discovered virus belongs to the polyoma family, which scientists have studied for more than 50 years because other members of the family have been found to produce cancers in animals. Although polyoma viruses have been suspected of causing human cancers, conclusive proof has been lacking. Merkel cancer cases have tripled over the past 20 years to about 1,500 a year, and about half the patients with advanced stages of the cancer live only nine months. Two-thirds die wi...
