It takes around two to three weeks after the vaccination or having the infection for the body to have enough antibodies to be able to fight the virus. The antibodies then stay in the blood at a low level, however, they can decline over time causing blood tests to no longer be able to detect them.
According to the ONS, there is an obvious pattern between vaccination and testing positive for the antibodies, however, the detection of only antibodies is not precise in measuring the immunity protection of having the vaccination.
It is also not yet fully know the length of time that antibodies remain detectable in the blood, or what the chances of getting the virus again are.
