Official Title
Neutralizing Antibody Level After COVID-19 Vaccination in Hospital Works.
Brief Summary

1. serial of neutralizing antibody at 2, 4, 6, 9, 12 month after COVID-19 vaccination 2. investigate the factors on antibody titer.

Detailed Description

1. serial of neutralizing antibody at 2, 4, 6, 9, 12 month after COVID-19 vaccination
1) semi-quantitative measurement of neutralizing antibody at 2, 4, 6, 9, 12 month
after COVID-19 vaccination 2) investigate the duration maintaining acceptable range
(over 30% inhibition)

2. investigate the factors on antibody titer at 2 month after vaccination 1) potential
factors: age, sex, body weight, height, use of medication, use of antipyretics
(NSAID or tyrenol), side effect of COVID-19 vaccination 2) correlation between
antibody titer and potential factors

3. Compare 4 diagnostic ELISA kit at 2 month after vaccination 1) measure neutralizung
antibody using ELISA kits from 4 different companies 2) investigate correlation
coefficient of antibody titer between companies

Recruiting
COVID19

Diagnostic Test: COVID-19 neutralizing antibody

This study enrolled persons already who received COVID-19 vaccination under government
policy.

1. We collect 5mL blood at 2, 4, 6, 9, 12 months after COVID-19 vaccination

2. isolate serum and store in -80 degree deep freezer

3. measure neutralizing Antibody
