Diverse spatio-temporal aspects of avian migration rely on relatively rigid endogenous programs. However, flexibility in migratory behavior may allow effective coping with unpredictable variation in ecological conditions that can occur during migration. We aimed at characterizing inter- and intraindividual variation of migratory behavior in a forest-dwelling wader species, the Eurasian woodcock , focusing on spatio-temporal consistency across repeated migration episodes.

Overall, it is still poorly known whether there is habitat selection amongst landbird migrants moving across landscapes. Europe is chiefly covered by agro-forestry mosaic landscapes, so migratory species associated to either agricultural landscapes or woodland habitats should theoretically find suitable stopover sites along migration.

The objective of this study was to compare a pediatric dose (0.25 mL) of Epaxal, a virosomal, aluminum-free HAV vaccine, to 0.

Methods: Healthy children 12- to 15-month-old were randomized to receive either a pediatric dose (0.25 mL) of Epaxal coadministered with DTPaHibIPV, oral polio vaccine, and measles-mumps-rubella vaccine (n = 109; group A), or Epaxal given alone (n = 105; group B), or Havrix Junior coadministered with DTPaHibIPV, oral polio vaccine, and measles-mumps-rubella vaccine (n = 108; group C).
Background: Travellers increasingly require hepatitis A virus (HAV) vaccine for overseas travel to highly endemic areas. While the inactivated HAV vaccines currently in use are all highly immunogenic, studies have shown the aluminium-free, virosome-adjuvanted vaccine Epaxal to possess a superior local tolerability profile. The objective of this study was to analyse the pattern of local reactions caused by the aluminium-free Epaxal compared with an aluminium-adjuvanted HAV vaccine.
