This can only be differentiated if you had both a total anti-HAV test and IgM test.The total is positive with both past infection or vaccination; the IgM is positive with current infection, recent infection, or recent vaccine. See this link for a chart with the different possibilities:https://www.cdc.gov/hepatitis/statistics/surveillanceguidance/docs/viral-hepatitis-surveillance-table-2-1_508.pdf
