Preliminary results: surveillance for Guillain-Barré syndrome after receipt of influenza A (H1N1) 2009 monovalent vaccine - United States, 2009-2010. However, later post-marketing and surveillance studies across multiple influenza seasons found comparable protection against influenza for LAIV and IIV, with findings of reduced effectiveness against A(H1N1) in some studies. 2000;181(3):831-7, Schanzer DL, Tam TW, Langley JM, Winchester BT. HA-based serum antibody produced to one influenza A subtype is anticipated to provide little or no protection against strains belonging to the other subtype. Nausea, vomiting, and diarrhea may also occur, especially in children. J Infect Dis. The IMPACT study also found that the proportion of deaths attributable to influenza was significantly greater for influenza B (1.1%) than influenza A (0.4%). IIV (IIV3-SD and IIV4-SD) and LAIV (LAIV4) are authorized for use in Canada for children 2–17 years of age. 2013;141(3):620-30, Reichert TA, Sugaya N, Fedson DS, Glezen WP, Simonsen L, Tashiro M.

NACI recommends that influenza vaccine should be offered annually to anyone 6 months of age and older who does not have contraindications to the vaccine. There are two categories of influenza vaccine authorized for use in Canada: inactivated influenza vaccine (IIV) and live attenuated influenza vaccine (LAIV). In Canada, influenza generally occurs each year in the late fall and winter months. If a quadrivalent vaccine is not available, a trivalent vaccine should be used.

In the NACI literature review on Influenza Vaccine Effectiveness, Immunogenicity, and Safety in Healthy Adults 19–64 Years Old, efficacy against laboratory-confirmed influenza for IIV3-SD in healthy adults 18–64 years of age ranged widely from as low as 15% to as high as 75%, with the majority of studies estimating efficacy at 50–60%. 2016;138(3):e20154643, Centers for Disease Control and Prevention. Evidence of bias in estimates of influenza vaccine effectiveness in seniors. Immunization safety review: influenza vaccines and neurological complications. After careful review of clinical and post-licensure safety data, NACI has concluded that egg-allergic individuals may be vaccinated against influenza using any appropriate product, including LAIV, without prior influenza vaccine skin test and with the full dose, irrespective of a past severe reaction to egg and without any particular consideration, including vaccination setting. Fifteenth pandemic pharmacovigilance update. Given the lack of data for immune interference, and based on expert opinion, NACI recommends that LAIV can be given together with or at any time before or after the administration of any other live attenuated or inactivated vaccine. Safety of influenza vaccination during pregnancy. However, children 6 months to less than 9 years of age who have not previously received the seasonal influenza vaccine require 2 doses of influenza vaccine, with a minimum of 4 weeks between doses (see Table 2). Serious adverse events were rare and similar in frequency between standard-dose and high-dose vaccines. During the 22 seasons in which influenza A(H3N2) was the prominent strain, the average influenza-associated mortality rates were 2.7 times higher than for the nine seasons that it was not (all age groups combined), and on average, there were about 37% more annual influenza-associated deaths, regardless of the underlying medical cause.

When available, IIV3-HD should be used over IIV3-SD, given the burden of influenza A(H3N2) disease and the good evidence of better efficacy compared to IIV3-SD in this age group. Greater rates of seroconversion to LAIV3 occurred in baseline seronegative individuals compared to baseline seropositive individuals in both pediatric and adult populations, because pre-existing immunity may interfere with response to a live vaccine. The Opening Solar Concentrator Updated 15 July 2020 2.2. The quadrivalent formulation (LAIV4) was approved for use in Canada for the 2014–2015 season and has been in use since that time.

In Nace et al., seroprotection was higher against A(H3N2) and B but not A(H1N1); this finding may be attributed to strain circulation during the study that made it difficult to assess seroprotection against this subtypeFootnote 133. children 6 months to 18 years of age undergoing treatment for long periods with acetylsalicylic acid, because of the potential increase of Reye’s syndrome associated with influenza. 2009;634:161-83, Rasmussen SA, Jamieson DJ, Bresee JS. The numeric suffix denotes the number of antigens contained in the vaccine (“3” refers to the trivalent formulation and “4” refers to the quadrivalent formulation). With the variety of influenza vaccines available for use in Canada, it is important for vaccine providers to note the specific differences in age indication, route of administration, dosage and schedule for the products that they will be using (see Table 2). Although influenza vaccine can inhibit the clearance of warfarin and theophylline, clinical studies have not shown any adverse effects attributable to these drugs in people receiving influenza vaccine. 2014;10(9):2721-8, Statistics Canada. There were concerns raised by a European Medicines Agency inspection about the quality of diagnostic laboratory testing and validity of ascertainment of influenza cases. Based on the body of evidence indicating a higher rate of influenza-associated hospitalization and death among Indigenous peoples, NACI recommends the inclusion of this population among the particularly recommended recipients of influenza vaccine.

London: European Medicines Agency. The ever-present possibility of antigenic drift, which may occur in one or more influenza virus strains, requires seasonal influenza vaccines to be reformulated annually, with one or more vaccine strains changing in most seasons. There remain no efficacy or effectiveness studies that compare IIV3-Adj with IIV3-HD or IIV4-SD. Transmission of influenza between infected HCWs and their vulnerable patients results in significant morbidity and mortality. NACI has concluded that there is insufficient evidence at this time to recommend routine influenza vaccination specifically for swine workers; however, NACI recommends that influenza vaccination should be offered to anyone 6 months of age and older who do not have contraindications to the vaccine.

Antibody responses to influenza B viruses in immunologically unprimed children. Laboratory detections over this same time period showed that influenza seasons in which influenza subtype A(H3N2) predominated, disproportionally affected adults 65 years of age and older, while seasons with greater A(H1N1) detections resulted in a higher prevalence of positive cases in younger age groups. Most studies have shown that administration of a second dose of influenza vaccine in the same season to older adults or other individuals who may have an altered immune response does not result in a clinically significant antibody boostFootnote 75,Footnote 76,Footnote 77,Footnote 78. 2000;355(9198):93-7, Hayward AC, Harling R, Wetten S, Johnson AM, Munro S, Smedley J, Murad S, Watson JM. 2006;12(1):48-54, Trombetta CM, Gianchecchi E, Montomoli E.

Intervirology. Up to expiry date indicated on vial label, Influenza is a respiratory infection caused primarily by influenza A and B viruses. In view of the considerable morbidity and mortality associated with influenza, a diagnosis of influenza vaccine allergy should not be made without confirmation, which may involve consultation with an allergy or immunology expert. FRANKFURT â The European economy shrank by a smaller than expected 0.7% in the last three months of 2020 as businesses in France and Germany weathered a renewed round of anti-COVID-19 lockdowns somewhat better than expected. LAIV, which is administered by the intranasal route, is thought to result in an immune response that mimics that induced by natural infection with wild-type viruses, with the development of both mucosal and systemic immunity. 2011;29(45):7878-82, Statistics Canada. Those who provide services within closed or relatively closed settings to people at high risk (e.g., crew on a ship).
