You will be shown a claim related to the COVID-19 pandemic, 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".
- "evidence": An array of sentences providing evidence for the verdict. Please copy all relevant sentences verbatim from the abstract.

For instance, if the model were given the claim "the COVID vaccine is safe for healthy adults", the output might be
{
  "verdict": "SUPPORT",
  "evidence": ["Our findings indicate that the risks of severe COVID vaccine side effects are low for healthy adults."]
}

Claim: Ferritin nanoparticle based sars-cov-2 rbd vaccine cans persistent antibody response and long-term memory in mice.

Abstract:
Since the outbreak of COVID-19, over 200 vaccine candidates have been documented and some of them have advanced to clinical trials with encouraging results.
However, the antibody persistence over 3 months post immunization and the long-term memory have been rarely reported.
Here, we report that a ferritin nanoparticle based SARS-CoV-2 RBD vaccine induced in mice an efficient antibody response which lasts for at least 7 months post immunization.
Significantly higher number of memory B cells were maintained and a significantly higher level of recall response was induced upon antigen challenge.
Thus, we believe our current study provide the first information about the long-term antibody persistence and memory response of a COVID-19 vaccine.
This information would be also timely useful for the development and evaluation of other vaccines.
