Brief Summary

Prospective cohort study to evaluate safety and immunogenicity of the fragmented, inactivated trivalent Influenza vaccine produced at Butantan Institute in healthy adults and elderly. The study will include a total of 120 participants: 60 participants aged 18 to 59 years in the healthy adults group, and 60 participants aged older than 60 years in the elderly group.This study will evaluate the safety of one dose of the fragmented, inactivated trivalent Influenza vaccine in the first 3 days after vaccination, as well as its immunogenicity 21 days after vaccination.

  21 days

• Vaccine safety assessed by unsolicited local and systemic adverse reactions up to 3 days post vaccination

  3 days

• To be available to participate in the study throughout its duration (approximately 21 days)
• To have medical indication to be vaccinated against influenza
• To demonstrate intention to participate in the study, as documented by signature in the study´s informed consent form.

You may not qualify if:

• Evidence of active neurological, cardiac, pulmonary, hepatic or renal disease as clinical history and/or physical examination (except hypertension under control among the elderly)
• Compromised immune system diseases including: HIV, diabetes mellitus, cancer (except basal cell carcinoma) and autoimmune diseases
• Behavioral, cognitive or psychiatric disease that in the opinion of the principal investigator or his representative physician, affects the participant ability to understand and cooperate with all study protocol requirements
