HAPPEX results from our 2005 run for the parity-violating asymmetry A{sub PV} in elastic scattering of 3 GeV electrons off hydrogen and {sup 4}He targets at ({theta}{sub lab}) {approx} 6.0{sup o} are presented. The {sup 4}He result is A{sub PV} = (+6.40 {+-} 0.23 (stat) {+-} 0.12 (syst)) x 10{sup -6}. The hydrogen result is A{sub PV} = (-1.58 {+-} 0.12 (stat) {+-} 0.04 (syst)) x 10{sup -6}. The asymmetry for hydrogen is a linear combination of G{sub E}{sup s} and G{sub M}{sup s}, the strange quark contributions to the electric and magnetic form factors of the nucleon, respectively, and that for {sup 4}He is a function of G{sub E}{sup s} alone. The measurements imply G{sub E}{sup s} + 0.09 G{sub M}{sup s} = 0.007 {+-} 0.011 {+-} 0.006 at = 0.109 GeV{sup 2} and G{sub E}{sup s} = 0.002 {+-} 0.014 {+-} 0.007 at = 0.077GeV{sup 2}.
