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