- Systemic reaction and local reaction (vital sign, temperature) [ Time Frame: 11/2 year ]
- Humoral immune response [ Time Frame: 11/2 year ]
Peak immunogenicity blood specimen and nasal washing for accessing immune response IgA.
Nasal swab on D2, D3, D5, D7 after immunization. Blood for ASC assay at D0 (baseline) and D7 after each dose of vaccine.

Other Name: GPO Flu Vaccine-01
|Placebo Comparator: Stabilizer||
Part A: 24 volunteers will be enrolled and divided into 2 groups -12 volunteers in each of 2 groups receiving either 5.0-6.5 log 10 EID50 or 6.6-7.5 log10 EID50 respectively. 9 who will received vaccine vaccine strain and 3 who will received placebo.
Part B: Total 324 participants will randomized into 2 group using 3:1 ratio (300 vaccines:100 placebos). There are 3 stratified age groups: >12-18 years, >18-49 years and >49 years.
