No antibody after Covaxin second dose
My mother took both doses of Covaxin it's been 15 days after second dose, I did Sars Cov 2 total antibodies and Antibodies against Spike protein both results came out negative less than 1 and less than 0.4 respectively. Want an expert opinion which is non diplomatic and practical i.e. does it proves that she has no protection against the Covid virus?
