Range of covid antibody after vaccine.

Hello sir/madam, My mother is having highest pain of life in knees. Her start of pain coincided with 1st dose of Sputnik & coincided with start of winter season. Her pain remains high during season change, but this time it is highest from 3 weeks, also she is feeling more cold due to old age this time that could be the reason for pain. Asking this question to pulmonogist because they are dealing with corona patients more. As mother's high pain could be due to high immune response from Sputnik (As Sputnik makes higher antibodies only by one dose too). Can you please tell what is the Value range of Covid Igg antibody in test after first dose & after second dose. If we know the difference of range for any vaccine between both doses then after test it can be decided should she continue second dose or not, because Sputnik already makes high antibodies after first dose. Please check/find the difference in value after both doses and let us know please??? As vaccination fr her is imprtant too
