NCT01368796

Brief Summary

Based on information from several years of looking at Influenza vaccination doctors know that:

  • Older adults suffer the worst illness and most deaths caused by Influenza illness of all age groups.
  • Older adults do not seem to get as good a level of protection as younger adults after getting the usual seasonal Influenza vaccine. Because of this information doctors wonder if one of the new seasonal Influenza vaccines is more effective or more acceptable. This study has been designed to answer some of these questions. On this study doctors will compare 2 new vaccines against the usual seasonal influenza vaccine for protectiveness using several different testing methods (including the usual tests) and for acceptability.

Outcome Measures

Primary Outcomes (1)

  • HAI response

    The primary outcome measures will be the 3-week post-vaccination immune (HAI) responses to the 3 vaccine strains present in each product, assessed by the EMEA/CHMP criteria for evaluation of immune responses to influenza vaccines in persons \>60 years of age.

    Day 0; Day 21; Day 180

Secondary Outcomes (2)

  • Seroprotection rates using microneutralization titres and cytokine testing

    Day 0; Day 21; and Day 70

  • Safety and Acceptability

    Days 0-6; Day 21; Day 70; and Day 180

Study Arms (4)

Trivalent Influenza vaccine subunit

ACTIVE COMPARATOR

The seasonal vaccine (Agriflu, Novartis) contains egg-derived, inactivated and detergent split versions of the 3 influenza strains (tri-valent). It is given into the muscle of the upper arm at a dose of 0.5 mL.

Biological: Agriflu

Adjuvanted Tri-valent Influenza Vaccine

ACTIVE COMPARATOR

The adjuvanted vaccine (Fluad, Novartis) is made with an immune-stimulator (MF59) that contains squalene oil microdroplets and two surfactants, Tween 80 and Span 65. It is given into the muscle of the upper arm at a dose of 0.5 mL.

Biological: Fluad

Intradermal Tri-valent Influenza vaccine

ACTIVE COMPARATOR

(Intanza 15ug, Sanofi Pasteur) is an inactivated, split-virion influenza vaccine. Strains are grown in fertilized hen's eggs, inactivated with formalin and split using Triton X-100 detergent, as for TIV. The syringe is attached to a micro-needle injection system (Beckton Dickinson) that limits the depth of injection to just under the skin. It is given into the skin over the upper arm at a dose of 0.1 mL.

Biological: Intanza

Trivalent Split-virion Influenza vaccine

ACTIVE COMPARATOR

Vaxigrip, Sanofi Pasteur is an inactivated, split-virion Influenza vaccine. The 3 influenza strains are grown on fertilized eggs, concentrated, purified in a sugar-like solution, detergent split, and inactivated by formaldehyde, then diluted in phosphate buffered salt solution. A dose of 0.5 mL is given into the muscle of the arm.

Biological: Vaxigrip

Eligibility Criteria

Age65 Years+
Sexall
Healthy VolunteersYes
Age GroupsOlder Adult (65+)

You may qualify if:

  • Written informed consent provided by the subject, who can be male or female
  • Subjects who the investigator believes can and will comply with the requirements of the protocol (i.e. return for follow-up visits, record safety observations and able to converse with study personnel including by personal telephone)
  • Age 65 years or older at Visit 1
  • Generally good health (stable chronic conditions acceptable), living independently or with minimal assistance (Clinical Frailty score 1-5) (33) and able to attend clinic appointments
  • Receipt of at least one dose of TIV within the previous 2 influenza seasons, documented by written record or attested by a confident personal recollection. This refers to the trivalent seasonal vaccine, not the H1N12009 pandemic vaccine.

You may not qualify if:

  • receipt of non-study influenza vaccine for 2011-12
  • receipt of any live vaccine within 4 weeks or inactivated vaccine within one week of Visit 1 or planned administration of any non-study vaccines between Visits 1 and 2
  • systemic hypersensitivity to influenza vaccine, hen's eggs or other vaccine constituent (eg neomycin sulphate, kanamycin, formalin)
  • severe reaction to any previous influenza vaccine or vaccine component
  • bleeding disorder, including anticoagulant therapy or thrombocytopenia, that contraindicates IM injection or blood collection (does not include daily low-dose ASA).
  • incapacity to provide fully informed consent or be attentive to follow-up observations, resulting from cognitive impairment, abuse of alcohol, drug addiction
  • lack of telephone access, inadequate fluency in English (or French in applicable jurisdictions), uncertain availability during the 3 week study participation period or for the 6 month follow-up visit
  • immune compromise resulting from disease or immunosuppressive systemic medication use within 3 months of V1
  • receipt of blood or blood product within 3 months of V1
  • unstable medical condition, as indicated by a requirement for hospitalization or a substantial medication change to stabilize said condition within previous 3 months
  • Clinical Frailty score of 6-7 (moderately frail or severely frail)
  • history of Guillain-Barré syndrome
