Good communication and trustworthy in terms of delivering work. Very polite. However, it feels the job was attempted without giving good attention to the questions and their exact requirements. This is reflected on the lack of quality of the overall work which will probably lose lots of marks if submitted like that. I had to consult other people to complete the job myself.

months of data going backwards and forwards. Forgot what had previously been said. Failed to proof read any work done as i would receive a document, explain the changes needed, and then received a new document with those errors changed but previous errors re-occuring. Limited communication.

Evaluation of a measles vaccine campaign by oral-fluid surveys in a rural Kenyan district: interpretation of antibody prevalence data using mixture models

Cambridge University Press

We evaluated the effectiveness of a measles vaccine campaign in rural Kenya, based on oral-fluid surveys and mixture-modelling analysis. Specimens were collected from 886 children aged 9 months to 14 years pre-campaign and from a comparison sample of 598 children aged 6 months post-campaign. Quantitative measles-specific antibody data were obtained by commercial kit. The estimated proportions of measles-specific antibody negative in children aged 0-4, 5-9 and 10-14 years were 51%, 42% and 27%, respectively,
