You will be shown a claim about public health, and the abstract of a biomedical research paper. Each sentence from the abstract will be on a separate line. Your task is to return a JSON object with two fields:

- "verdict": The fact-checking verdict. If the information in the abstract supports the claim, write "SUPPORT". If the abstract contradicts the claim, write "CONTRADICT". If the abstract does not provide enough information to arrive at a verdict, write "NEI" (for "not enough information").
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract. If the verdict was "NEI", then return an empty array.

For instance, if the model were given the claim "wearing masks can prevent the spread of COVID", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that mass mask-wearing reduces the transmission rate for COVID-19."]
}

Claim: BCG vaccine can boost the immune system enough to prevent healthcare workers from catching coronavirus.

Abstract:
So far, there is a lack of effective drugs for the new coronavirus pneumonia.
With more and more patients diagnosed, China has carried out more than 100 clinical studies of new coronavirus infection, including antiviral drugs, antimalarial drugs, glucocorticoids, plasma therapy, virus vaccine, and other Western drugs, while Chinese medicine research accounted for half of the studies.
Most of the trials were initiated by investigators and the study period would last for 1 to 11 months.
The primary endpoints included symptom improvement and virus nucleic acid turning negative, but the optimal endpoint has not been determined.
Although the final results of studies will take a long time to complete, the interim research data may provide some help for the current urgent demand for drug treatment.
Compared with that of during SARS period in 2003, China has the stronger capability to carry out clinical trials of new drugs in emergency period.
