Weaver, acting as the Director of Research at the National Foundation for Infantile Paralysis, now known as the March of Dimes,from 1946 to 1953, supported Salk's work with a sense of urgency for the development of the Polio vaccine. Weaver's urgency for developing a vaccine as quickly as possible was somewhat counter to the development of the Oral polio vaccine by Albert Sabin between 1954 and 1961. However, his support of Salk's vaccine was considered to
David Bruce (microbiologist) discouraged the experiments being carried by Zammit, and doubted his ability as a microbiologist.
