Sensitivity analyses showed our results were reasonably robust to varying assumptions regarding the number of doses received through regimen immunization and that trivalent oral polio vaccine was consistently far better against paralysis from type 2 cVDPV than against paralysis from type 1 or type 3 WPV . Vaccine-Induced Inhabitants Immunity Estimated vaccine-induced population immunity to type 1 WPV poliomyelitis increased in all zones from 2005 to 2009 significantly, particularly in the North West and North East zones .8 percent annually). Estimated vaccine-induced human population immunity to type 3 WPV poliomyelitis increased significantly in the North West and North East zones and declined significantly in two of the various other four zones.At 18 months, only 6.5 % in the simultaneous arm, 5.2 % in the sequential arm and 6.5 % in the usual-care arm met the primary end point, or changing two of the three behaviors, the authors write. However, results for one behavioral goals favored the simultaneous group consistently. For example, after six months, 29.6 % in the simultaneous, 16.5 % in the sequential and 13.4 % in the usual-care groups had reached the urine sodium goal. After 18 months, 20.3 % in the simultaneous, 16.9 % in the sequential and 10.1 % in the usual-care groups tested unfavorable for urine cotinine, which the physical body produces when it metabolizes nicotine, indicating they had stopped smoking.
