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: Prior infection by seasonal coronaviruses does indeed prevent sars-cov-2 infection and associated multisystem inflammatory syndrome in children

Abstract:
Background: Children have a lower rate of COVID-19, potentially related to cross-protective immunity conferred by seasonal coronaviruses (HCoVs).
We tested if prior infections with seasonal coronaviruses impacted SARS-CoV-2 infections and related Multisystem Inflammatory Syndrome (MIS).
Methods: This cross-sectional observational study in Paris hospitals enrolled 739 pauci or asymptomatic children (HOS group) plus 36 children with suspected MIS (MIS group).
Prevalence, antigen specificity and neutralizing capability of SARS-CoV-2 antibodies were tested.
Antibody frequency and titres against Nucleocapsid (N) and Spike (S) of the four seasonal coronaviruses (NL63, HKU1, 229E, OC43) were measured in a subset of seropositive patients (54 SARS-CoV-2 (HOS-P subgroup) and 15 MIS (MIS-P subgroup)), and in 118 matched SARS-CoV-2 seronegative patients (CTL subgroup).
Findings: SARS-CoV-2 mean prevalence rate in HOSP children was 11.7% from April 1 to June 1.
Neutralizing antibodies were found in 55.6% of seropositive children, and their relative frequency increased with time (up to 100 % by mid-May).
A majority of MIS children (25/36) were SARS-CoV-2 seropositive, of which all tested (n=15) had neutralizing antibodies.
On average, seropositive MIS children had higher N and S1 SARS-CoV-2 titres as compared to HOS children.
Patients from HOS-P, MIS-P, and CTL subgroups had a similar prevalence of antibodies against the four seasonal HCoVs (66.9-100%).
The level of anti-SARS-CoV-2 antibodies was not significantly different in children who had prior seasonal coronavirus infection.
Interpretation: Prior infection with HCoVs does not prevent SARS-CoV-2 infection and related MIS in children.
Children develop neutralizing antibodies after SARS-CoV-2 infection.
{"verdict": "CONTRADICT", "evidence": ["The level of anti-SARS-CoV-2 antibodies was not significantly different in children who had prior seasonal coronavirus infection."]}
