NIH, drug companies working to develop Ebola vaccine

Just months after the Ebola outbreak in Africa began spreading last spring, the National Institutes of Health (NIH) started human testing a vaccine to prevent the deadly Ebola virus, and the U.S. Department of Defense announced it is also working to develop a vaccine for the virus. Drugs to treat serious and life threatening illnesses can be granted expedited review by the Food and Drug Administration (FDA) to speed technologies and prevent possible spread of infectious disease. With Ebola becoming more of a global threat than ever before, the agency is allowing researchers with GlaxoSmithKline and the National Institute of ... Read More

Rotavirus vaccine increases risk of serious intestinal disorder in infants, children

Infants given the rotavirus vaccine, which protects against the most common cause of severe diarrhea in children and babies, are at risk of developing a serious intestinal disorder, according to a study conducted by a Harvard researcher. The risk is small but concerning. The disorder, called intussusception, occurs when one portion of the bowel slides into the next in sort of a telescope effect. When this occurs, it can create a blockage in the bowl causing swelling, inflammation and decreased blood flow to part of the intestines. Prognosis is good if detected early, but if treatment is delayed, the consequences ... Read More

Nearly 750,000 Gardasil vaccines recalled due to possible contamination

Hundreds of thousands of Gardasil vaccines are being recalled because they may be contaminated with little bits of glass, according to a statement released by Merck & Co. While no injuries have been reported, if administered, the contaminated vaccines may cause health complications such as a reaction at the injection site. Nearly 750,000 vaccines are involved in the recall, however Merck says only about 10 vials may have been affected. The problem stems from a breakdown in production. The affected vaccines were distributed in the United States and Puerto Rico between Aug. 20, 2013 and Oct. 9, 2013. Nearly half of the ... Read More

Hepatitis B vaccine recalled due to sterility issues

Vials of the hepatitis B vaccine RECOMBIVAX HB are being recalled by the manufacturer because a limited number of the vials in the lot may crack, the Food and Drug Administration (FDA) announced. If a crack occurs, the integrity of the vial and the sterility of any product remaining in the vial could not be assured. Merck Sharp & Dohme Corp., a subsidiary of Merck & Co., issued the recall for Lot Number J001183 of RECOMBIVAX HB (Recombinant) Adult Formulation. The product was distributed only in the United States between March 12, 2013, and May 2, 2013. The company says ... Read More

CDC urges US hospitals to be on the lookout for patients with bird flu

The Centers for Disease Control and Prevention (CDC) is hoping to stop the H7N9 avian flu from spreading throughout the United States by asking hospitals to be on the lookout for people with flu-like symptoms who have traveled to China or have had contact with someone who has the illness. The center also issued interim guidance on the use of antiviral drugs to treat patients with the bird flu. The avian flu has infected at least 92 people in China, resulting in 17 deaths. The source of the infections has not yet been identified and there are no known instances ... Read More

2009 swine flu vaccine linked to paralyzing disease

The H1N1 (swine flu) vaccine given in the United States in 2009 was associated with a slight increased risk of developing Guillain-Barre syndrome, a rare paralyzing disease, a new study shows. However the authors say the benefits of the flu shot outweigh the risks. Guillain-Barre syndrome is a disorder in which the body’s immune system attacks the nerves. It usually begins with weakness and tingling in the hands or feet that can quickly spread and paralyze the entire body. People with the most severe form of the disorder require medical attention and hospitalization. Most people recover from the disorder though some ... Read More

Swine flu shot linked to cases of narcolepsy in children

About 800 children throughout Europe have developed narcolepsy, an incurable sleep disorder, after being immunized with the Pandemrix H1N1 swine flu vaccine made by GlaxoSmithKline, according to a soon-to-be published study in Britain. Concern over the condition and its ties to the flu shot have led Europe’s drug regulators to rule that Pandemrix not be given to people younger than age 20. Pandemrix has been given to more than 30 million people in 47 countries, including Sweden, France, Norway, and Ireland, during the 2009-2010 swine flu pandemic. The vaccine contains an adjuvant, or booster sometimes included in vaccines to enhance ... Read More

Forty-seven states reporting widespread flu outbreaks

The 2012-2013 flu season is shaping up to be a doozy. So far, 47 states are reporting widespread outbreaks of the influenza virus, and two states have declared public health emergencies. One doctor told CBS News that the flu is traveling “like a chain letter, it’s exponential.” In Alabama, the number of cases are steady but no higher than they were during the swine flu epidemic of 2009. The only states that aren’t seeing widespread infections are California, Mississippi and Hawaii, according to the Centers for Disease Control and Prevention (CDC). New York declared a public health emergency this week after ... Read More

Two autopsies reveal Gardasil antigens entered brain, potentially triggering inflammation and death

A postmortem analysis of two girls from different parts of the world who died after receiving injections of Merck’s human papillomavirus (HPV) vaccine Gardasil has uncovered some astonishing evidence that components of the vaccine may be capable of triggering auto-immune diseases and even death. The study, conducted by Dr. Chris Shaw of the University of British Columbia and Dr. Lucija Tomljenovic from the Neural Dynamics Research Group in Vancouver, and published in the journal Pharmaceutical Regulator Affairs, examined brain tissue samples taken from the deceased girls. The researchers found particles of two HPV antigens used by Merck to produce the ... Read More

Whooping cough vaccine loses effectiveness soon after last dose

Researchers have uncovered some disappointing news in the battle against the nation’s largest whooping cough outbreak in decades. The safer vaccine, introduced in the 1990s, loses its effectiveness much faster than previously thought. The study, published this week in the New England Journal of Medicine, found that the vaccine’s effectiveness wears off soon after a child gets the last of five recommended doses, around the age of 6. Within five years, the immunity rate falls from about 95 percent to 71 percent. More than 26,000 whooping cough cases were reported this year in the United States; nearly half of those ... Read More
