question:
Low doses of the drug FTY720, also called fingolimod, given  to mice once a day for three days eliminated an infection by a  virus that can cause meningitis, an inflammation of the  membranes surrounding the brain and spinal cord. The findings suggest the drug, which boosted anti-viral  immune responses in the mice, may be useful against viruses  that cause high-level, long-lasting infections in people such  as hepatitis C and HIV, the researchers said. Microbiologist and immunologist John Altman of Emory  University in Atlanta, who led the study, said the researchers  plan to assess the effects of the drug on other viruses  including the monkey version of the AIDS virus. Altman, whose findings were published in the journal  Nature, expressed cautious optimism that the drug might work  against certain chronic viral infections in people. “We think it’s crucial that we do experiments to check it  out,” Altman said in a telephone interview. The drug is generally considered to be an immunosuppressant  that works to restrain the body’s natural defenses. That could be helpful in multiple sclerosis, an autoimmune  disease in which the immune system attacks body parts as if  they were foreign invaders. But one effect of the drug seems to facilitate the immune  response, the researchers said. FTY720 among other things traps  white blood cells — key soldiers in the immune system’s fight  against infections — in the lymph nodes, Altman said. With viral infections, the lymph nodes are where the immune  response can get primed and started, Altman said. Some viruses  replicate themselves at high levels in lymph nodes, including  the human immunodeficiency virus that causes AIDS. They tested the drug against a mouse virus called  lymphocytic choriomeningitis, which causes chronic infections  by escaping immune responses. “In the absence of treatment (with FTY720) we have an  exhausted immune response. In the presence of treatment, we  regain a robust cellular immune response,” Altman said. Swiss drug maker Novartis said in June two multiple  sclerosis patients taking FTY720 in clinical trials had  problems with infections and one died, but the role of the drug  in the cases was unclear. Novartis plans at the end of 2009 to seek approval by the  European Union for FTY720 to treat MS, spokeswoman Valerie Tate  said by e-mail. The drug is currently in late-stage trials. Altman said his study was backed by the U.S. government’s  National Institutes of Health and was not funded by Novartis.
answer:
MS drug may work against viral infection: study.


question:
The shutdown began in late March in the Pacific nation of about 5 million, and a state of national emergency was declared to stifle local transmissions of the respiratory disease. “No one goes home, everyone goes into a managed facility,” Prime Minister Jacinda Ardern said, adding that 14 days spent in a government-approved facility would be a prerequisite for all foreign travellers. “Even one person slipping through the cracks and bringing the virus in can see an explosion in cases, as we have observed with some of our bigger clusters,” she told a media briefing in Wellington on Thursday. Ardern added that her cabinet would decide whether to extend the nationwide curbs on April 20, two days before the lockdown is set to end. The lockdown has reduced domestic transmissions, authorities said, with a steady fall this week in the daily rise in infections. The tally of infections rose by 29 to stand at 1,239 on Thursday, for the lowest daily rise since March 21, a sign the epidemic could be on the retreat since the lockdown began 15 days ago. Overnight, 35 people were declared to have recovered. New Zealand, like neighbouring Australia, has fewer infections than many countries and the pace of infections in both nations has slowed dramatically in the past week. Despite some signs of a plateau in infections, the government said it had no plans to relax the curbs over the Easter weekend and warned of hefty fines for non-essential travel then. Police will step up activity around holiday spots during the Easter holidays, authorities said, with some roadblocks planned.

question:
The Kansas Department of Health and Environment announced Thursday that students entering kindergarten and first grade will need two doses of a hepatitis A vaccine. Students entering seventh grade will need one dose of the meningococcal ACWY vaccine. And students starting their junior year will need the meningococcal ACWY vaccine if they have not been vaccinated before their 16th birthday. The new requirements take effect Aug. 2. Kansas allows exemptions from vaccines only for medical and religious reasons. Health department Secretary Lee Norman said the agency collected public input before proposing the new requirements. He said meningitis and hepatitis A are both severe diseases that are preventable with vaccines.
answer:

2 new vaccines required for some Kansas school students.
