I understand there has been study to check level of antibodies, could I please have that data ?
I am interested to find out what were the antibody level after two doses of astrazenca
I also would like antibody level after 2 doses of pfizer ?
Can this data be grouped by age groups ?
If this is not possible then please provide average antibody level after 2 doses of astrazenca
and 2 doses of pfizer broken down by vaccine type ?

Thank you for your request.
The COVID-19 infection survey (CIS) is a household survey which refers to the number of current COVID-19 infections within the community population; community in this instance refers to private residential households and it excludes those in hospitals, care homes or other institutional settings.
In the dataset accompanying our latest antibodies bulletin, you can find the modelled percentage of the adult population testing positive for antibodies to Covid 19 broken down by age group on tab 1c for England, 2b for Wales, 3b for Northern Ireland, and 4b for Scotland.
Our academic partners have published a paper on antibody levels and waning by vaccine type which can be found here, and an additional paper on antibody levels following second doses can be found here.
