You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: Importantly , we still do not know the extent to which positive results by serology reflect a protective immune response nor how long such protection might last . 30 Neutralization assays measure the ability of blood - derived samples to prevent viral ( most commonly pseudovirus ) infection of cultured cells in vitro . 31,32 Although these assays provide information on the functional capabilities of an individual 's antibodies , their correlation with total IgG antibodies to serological test antigens ( primarily spike and nucleocapsid proteins ) is not well established . Additionally , most antibody neutralization assays are research laboratory - based with limited test performance data and inter - lab standardization measures . Antibody neutralization assays should be harmonized across laboratories to establish the extent to which conventional serology assays correlate with neutralization . Further studies are needed to assess the relationships among positive serological testing , in vitro viral neutralization results , and clinical protection from future SARS - CoV2 infection and transmission . Epidemiological data and results from convalescent plasma treatment trials should help guide clinical and public health policies for use of serological testing .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
