How long after a person has been vaccinated (give all three shots) does it take to build an antibody response?
When would you advise getting an antibody test? Right after the third shot? Or a month later?
Thank you for your response.

Most healthy individuals respond to HBV vaccination so the Centers for Disease Control doesn't routinely recommend testing to antibodies after vaccination. Antibody testing can be considered in certain circumstances of high risk. For example, if your sexual partner is a chronic HBV carrier, then you would definitely want to get tested.
I usually test antibody responses about 2 weeks after vaccination, which is sufficient time to see a response.
