Reporting Groups
  Description
Mild/Moderate Asthma, Low Dose Vaccine (15mcg) Participants with mild-to-moderate asthma received one 15 micrograms (mcg) dose of unadjuvanted,[1] inactivated Novartis H1N1 pandemic influenza vaccine by intramuscular injection on Day 1 and Day 21.
Mild/Moderate Asthma, High Dose Vaccine (30mcg) Participants with mild-to-moderate asthma received two 15 mcg doses of unadjuvanted,[1] inactivated Novartis H1N1 pandemic influenza vaccine by intramuscular injections on Day 1 and Day 21.
Severe Asthma, Low Dose Vaccine (15mcg) Participants with severe asthma received one 15 mcg dose of unadjuvanted,[1] inactivated Novartis H1N1 pandemic influenza vaccine by intramuscular injection on Day 1 and Day 21.
Severe Asthma, High Dose Vaccine (30mcg)

Participants with severe asthma received two 15 mcg doses of unadjuvanted,[1] inactivated Novartis H1N1 pandemic influenza vaccine by intramuscular injections on Day 1 and Day 21.

[1] Unadjuvanted: No agents added to, or used in conjunction with, vaccine antigens to augment or potentiate (and possibly target) the specific immune response to the antigen. (U.S. Food And Drug Administration)
