A needleless IV injection port assembly (100) includes a spiked body (102) provided with a hollow spike (104), a female luer component, a flexible and resilient spike boot (108) having a tip (170) and spring portion (172), a centering member (110), and a resilient swabbable septum (112). When a separate male luer is positioned over a protuberence on the septum (112) and pushed into the female luer component, the male luer urges the septum (112) toward the spike (104), causing the spring portion (172) of the boot (108) t o be compressed and the tip portion (170) of the boot to be pierced by the tip of the spike (104). The injection port causes minimal reflux, and the spike boot (108) and septum (112) provide a swabbable antibacterial double barrier over the spike (104).
