Definitely something fishy going on.
I am taking part in the ONS/Oxford Covid survey.
Monthly blood and swab tests. All Covid negative so far.
I have had jab1 of the AZ vaccine and the first blood/swab test past that date after just under 4 weeks shows a negative antibody result.
had her jab1 a week after me and came back antibody positive.
I am waiting to see what happens after jab2 with test results.
So....a few things to think about.
Am I slower producing antibodies? One possibility thought to happen due to natural variation. There may just be a delay due to natural variation.
Am I in the small percentage the vaccine doesn’t work with? Will the second kick in antibody development?
Was the test a false negative?
A possibility is very low antibody production that the test can miss as mentioned in the literature.
Was the test done correctly?
I think we are lucky being part of the survey as the regular testing has thrown up my individual circumstance re no antibodies. I wonder who else is in the same situation but doesn’t know?
When asked about joining the survey it was a no-brainer to say yes for two reasons. Firstly to help with the survey and secondly to get regular testing as a bonus.
One thing that I am thinking about is how will my neg antibody result be dealt with re vaccine effectiveness both for myself and in the overall statistics picture for the management of the pandemic.
I will we watching my next test results. Next test in about 2 weeks then a few days before results.
Fingers crossed!
