FLAMINGO, FL - AUGUST 12: The a female mosquito begins to bite the photographer's hand at Everglades National Park August 12, 2002 in Flamingo, Florida. The female bugs use the blood protein to feed their eggs then lays the eggs in water. The itch from the bite is caused by the human body's immune system responding to the mosquito's saliva. During the summer, the Everglades closes its camping facilities almost entirely because of the onslaught of mosquitoes. Traps are put up throughout Flamingo where 250,000 mosquitoes a day are collected. (Photo by Tom Ervin/Getty Images)

"Iseult", the world's most powerful MRI scanner, has delivered its first images of the human brain and is expected to provide a better understanding of its functioning and of certain neurodegenerative and psychiatric diseases. The technical feat is the result of a French-German partnership which has required more than 20 years of research. (Photo by Alain JOCARD / AFP) (Photo by ALAIN JOCARD/AFP via Getty Images)

MIAMI, FL - SEPTEMBER 21: A bottle of the Human Papillomavirus vaccination is seen at the University of Miami Miller School of Medicine on September 21, 2011 in Miami, Florida. The vaccine for human papillomavirus, or HPV, is given to prevent a sexually transmitted infection that can cause cancer. Recently the issue of the vaccination came up during the Republican race for president when Rep. Michele Bachmann (R-MN) called the vaccine to prevent cervical cancer "dangerous" and said that it may cause mental retardation, but expert opinion in the medical field contradicts her claim. Texas Gov. Rick Perry, also a presidential contender, has taken heat from some within his party for presiding over a vaccination program in his home state. (Photo by Joe Raedle/Getty Images)

This recent archive picture, taken 17 August 2023 and distributed Tuesday 26 September 2023, shows a package with Ozempic medicine at a hospital in Bonheiden. The Belgian federal medicines agency (FAMHP-FAGG-AFMPS) recommends that doctors and pharmacies reserve the drug Ozempic as a priority for diabetics. There is limited availability of Ozempic due to an acute increase in demand. The drug is also popular as a slimming agent and is often prescribed off label for this purpose. The Step Young research program is running in the university hospitals of Brussels, Leuven and Antwerp. The Danish pharmaceutical giant Novo Nordisk wants to determine whether injections with 2.4 milligrams of semaglutide, the active substance of the weight loss drug Ozempic, are safe and effective for losing weight in obese 6 to 12-year-old children.
