WASHINGTON (The Blaze/AP) -- The government is prepared with a stockpile of the anthrax vaccine should a widespread bioterror attack ever take place, but there is a segment of the population that experts are unsure how they will react: children.
"We can't just assume that what we have for adults works for children," Health and Human Services Secretary Kathleen Sebelius told a bioethics panel Thursday.
Last fall, Sebelius has asked the Presidential Commission for the Study of Bioethical Issues to discuss whether or not the anthrax vaccine -- and other vaccines that could prove useful in a bioterror event -- should be tested on children. It decided that the vaccine testing should be allowed but with a caveat: only if ethical issues can be agreed upon.
The commission began its deliberations Thursday; recommendations are expected by year's end.
Sebelius made clear that the question is far broader than anthrax.
"There are serious ethical issues around the development of medical countermeasures for children" in general, she said.
Developing protections for youngsters is critically important, but in a way that puts "our children's safety as our highest priority," Sebelius said.
A decade after the anthrax attacks in the United States, the government has a multibillion-dollar stockpile of tools to fight back against some of the threats that worry defense experts. Notably missing is information on how to treat children in various emergencies -- whether the same drugs their parents will get will work or be safe for them, and even what dose youngsters should receive.
Thus the debate on whether to conduct studies now, before millions of children might need to try an untested product in an emergency. Even if those studies were offered, there's no way to know how many parents would agree to enroll their children.
Testing medications in children always requires extra safeguards. It's fairly straightforward to test a potential treatment for cancer or some other childhood disease. But if a child won't receive a direct medical benefit, federal regulations say studies are allowed only if testing adults can't provide the answers and if the risks to participating children are minimal.
Anyone exposed during an anthrax attack would require 60 days of powerful antibiotics, or antibiotics until a vaccine could kick in.
The shots have been widely used in adults, including U.S. troops, and are considered safe for them, said the board chairman, Dr. John Parker, a retired Army major general who has been vaccinated.
Side effects include shot-site soreness and redness, muscle aches, fatigue and headache. Rare but serious allergic reactions have been reported.
The bioethics commission wrestled with how to define "minimal risk" when there is no imminent emergency, and the chairwoman, Dr. Amy Gutmann, wondered whether people urging such testing would enroll their own children.
Parker responded that he's discussed that with first-responders and some in the military. "There are groups out there that would want their families protected as much as they are protected as they do their job, in fear of bringing something home," he said.
Other doctors told the panel that 60 days of antibiotics can cause bad side effects for children, including diarrhea, other infections and dangerous allergic reactions. Plus there's concern that many people wouldn't take the full course, Parker said.
The journal Nature reported that not all considered a trial on children as necessary just yet. It reports Nicola Klein, co-director at Kaiser Permanente Vaccine Study Center, saying she doesn't think the threat of an anthrax attack is enough yet to merit a trial of the vaccine on children.
