build trust in vaccines. Furthermore, EIW was used by the WHO field office in Gaziantep, Turkey, as a platform to celebrate progress and strong partnerships with UNICEF and the Syria Immunization Group (SIG) to increase immunization coverage among children in north-western Syria. In Denmark, WHO and UNICEF collaborated on a joint photo and video exhibit showcasing the importance of strong partnerships to tackle issues related to outbreaks of vaccine-preventable diseases, particularly in hard-to-reach areas as well as in the midst of humanitarian crises. WHO/Europe’s Patron, The Crown Princess of Denmark visited the exhibit prior to its official opening on 23 April and stated that vaccines are “at the heart of advancements in health protection and well-being”.

EIW was also utilized to launch the introduction of inactivated polio vaccine (IPV)Coating of two polyether-polyurethanes and polyethylene with a heparin-poly-(vinyl alcohol) hydrogel.
Two polyether-polyurethane elastomers (Pellethane and Biomer) and polyethylene were coated with a heparin-poly(vinyl alcohol) hydrogel. The requisite surface modification in preparation for coating consisted of glow discharge cleaning and acid treatment for the polyether-polyurethanes and glow discharge cleaning and chromic acid oxidation for polyethylene. The chemical modifications increased surface wettability. Surface analysis by attenuated total reflectance Fourier transform infrared spectroscopy indicated that the acid treatment caused hydrolysis of the polyether segments of Pellethane and Biomer. Prolonged partial thromboplastin times were observed on the coated films. The results of toluidine blue assay of heparin in the solution in which the coated films were immersed for a long time suggested that heparin was covalently bound in the coating. Such coating
