A member asked:
Is 137.1 (< .8 standard range) on a sars-cov-2 semi-quantitative total antibody (spike) test from labcorp months after vaccination similar to other vaccine antibody responses? what are typical numbers from that test after vaccination? am i protected?

Good response with vaccine but the current CDC guidelines recommend us not using the antibody result to assess if a person is protected from Covid-19 infection or not. However, to say it with common sense if your body develops antibody after a vaccine you are somewhat protected but more studies, especially after CDC has all the info regarding the breakthrough cases, we will know more.
