PRIMARY outcome

Timeframe: At day 30

Population: The Overall Number of Participants analyzed for "IIV Flu Vaccine with Antibiotics" is 15, as one participant received antibiotics and did not receive vaccine. The study personnel were unable to draw blood on her at the vaccination day- therefore she was part of the safety population and not the immunogenicity population.

Number of participants with four fold rise in HAI titers or HAI 1:40 and above in each group at D30 will be recorded based on immunologic testing of blood samples
