Study population: Participants who received first dose of ChAdox-1 n COV-19 were recruited.

Brief summary: ChAd0x1 nCoV-19 (AZD 1222) is the main vaccine that is planned to roll-out in Thailand and involve vaccinating people especially in high-risk categories. This vaccine is contained in the multiple-dose vial for vaccinating 10 recipients for 0.5 mL each. However, the additional volume of vaccine was overfilled to 6.5 mL per vial which the vaccination can be administered to more than 10 doses. The University Hospital Network (UHOSNET) and Faculty of Medicine Vajira Hospital, Navamindradhiraj University have jointly stipulated the preparation and vaccination of ChAdox1 - n CoV-19 vaccine with 12 doses per vial injection with traditional 21 or 24 G needle. Taken together, The investigators planned to investigate the immune response of participants after first dose of ChAd0x1 nCoV-19 vaccination with such technique

Detailed description: The investigators measured anti-SARS-CoV-2 antispike RBD IgG and neutralizing antibody by surrogate virus neutralizing test (sVNT) in adults between age 18-72 year after first dose of ChAd0x1 nCoV-19 vaccine.The primary outcome was the antibody levels.The secondary outcome were adverse events,factors affecting antibody levels and incidence of COVID-19 infection at the time of study

Eligibility criteria: Inclusion Criteria:

* Participants were eligible if they were more than 18 years old.

Exclusion Criteria:

* Allergic to components of vaccine
