Health Care Workers First to Receive U.S. Swine Flu Shots
Doctors, paramedics and other health-care workers in Indiana, Illinois and Tennessee were the first Americans to receive the H1N1 swine flu vaccine as the U.S. government commenced its nationwide immunization effort Monday.
People who lined up for the vaccine got it as FluMist, a nasally delivered spritz initially reserved for front-line health-care workers, according to the Associated Press. Only 7 million doses of vaccine are expected to be delivered nationwide by the end of the week. Most states are expected to reserve these early shipments for doctors and other medical personnel.
"I needed that protection," Dr. John Eshun, a gastroenterologist standing in line at Le Bonheur Children's Hospital in Memphis, Tenn., told the AP.
By mid-October, more than 40 million doses of H1N1 vaccine are expected to have been distributed, according to the AP. Some states, such as Arkansas and Pennsylvania, are reserving this week's expected stock of vaccine for in-school vaccinations.
American Scientists Receive Nobel Prize in Medicine
Three American scientists were awarded the 2009 Nobel Prize in medicine Monday for their genetic discovery that could lead to new cancer treatments.
Elizabeth H. Blackburn, Carol W. Greider and Jack W. Szostak found that an enzyme called telomerase may play a role in the uncontrolled growth of cancer cells, the Associated Press reported.
Researchers are currently studying whether drugs that block the enzyme are effective against cancer and whether telomerase may be involved in other diseases.
"The discoveries by Blackburn, Greider and Szostak have added a new dimension to our understanding of the cell, shed light on disease mechanisms, and stimulated the development of potential new therapies," the Nobel prize committee said in its citation, the AP reported.
Committee members said this is the first time that two women have been among the winners of the medicine prize.
Blackburn is a professor of biology and physiology at the University of California, San Francisco. Greider is a professor in the department of molecular biology and genetics at Johns Hopkins University School of Medicine. Szostak is a professor of genetics at Harvard Medical School.
USDA, FDA to Team Up on Food Safety
The head of fresh produce at the U.S. Department of Agriculture will work with the federal Food and Drug Administration to help develop new food safety rules.
The partnership is part of a joint initiative between the two agencies and comes amid efforts to improve food safety in the United States in the wake of high-profile food contamination outbreaks in recent years.
Leanne Skelton, chief of the USDA Agriculture Marketing Service's fresh products branch, will work with the FDA for six months to help the FDA develop new safety regulations for produce.
