Quadrivalent influenza vaccine: What is changed and what are the benefits?

Currently, circulating viruses responsible for annual seasonal influenza epidemics belong to two influenza A subtypes, A(H1N1) and A(H3N2), and to two antigenically distinct type B lineages, B/Yamagata and B/Victoria lineages. Like diseases due to influenza A virus, influenza B virus diseases may have severe consequences and should be prevented. Until now, in France, the vaccines used to prevent seasonal influenza were trivalent, systematically targeting viruses belonging to both A subtypes and to one or ot...


Enhanced Safety Surveillance of Seasonal Quadrivalent Influenza Vaccines in English Primary Care: Interim Analysis.

The European Medicines Agency (EMA) requires vaccine manufacturers to conduct enhanced safety surveillance (ESS) of seasonal influenza vaccines including a near real-time evaluation of collected data. The objective was to identify whether the use of passive surveillance or active surveillance provides different results of reported adverse events of interest (AEIs) by specified age strata and AEI type. We report the weekly incidence rates of AEIs within 7 days following seasonal influenza vaccination using ...

DNA vaccine priming for seasonal influenza vaccine in children and adolescents 6 to 17 years of age: A phase 1 randomized clinical trial.

Children are susceptible to severe influenza infections and facilitate community transmission. One potential strategy to improve vaccine immunogenicity in children against seasonal influenza involves a trivalent hemagglutinin DNA prime-trivalent inactivated influenza vaccine (IIV3) boost regimen.


Anamnestic Immune Response and Safety of an Inactivated Quadrivalent Influenza Vaccine in Primed Versus Vaccine-Naïve Children.

It has not yet been demonstrated whether two doses of inactivated quadrivalent influenza vaccine (IIV4) prime a booster response in infants. We evaluated the anamnestic immune response to an IIV4 in children aged 17-48 months.

Perceptions of Seasonal Influenza and Pneumococcal Vaccines Among Older Chinese Adults.

Seasonal influenza can lead to pneumonia. In Hong Kong, deaths from pneumonia increased steadily from 2001 to 2015, and pneumonia was the second most common cause of death between 2012 and 2015. The seasonal influenza vaccine and pneumococcal vaccine have been clinically proven as effective measures against these two diseases among older adults, who are at particularly high risk. Despite the availability of vaccine subsidies, however, more than 60% of older adults in Hong Kong remain unvaccinated against pn...

Technical guidelines for seasonal influenza vaccination in China, 2018-2019.

Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and its complications. Currently, China has licensed trivalent (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. In most parts of China, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients need to pay for it. To strengthen the technical guidance for prevention and control of influenza and...

Seasonal influenza vaccine effectiveness at primary care level, Hong Kong SAR, 2017/2018 winter.

The 2017/18 winter influenza season in Hong Kong SAR started in early January 2018, predominated by influenza B/Yamagata. We collaborated with private medical practitioners of our sentinel surveillance system to collect respiratory specimens and clinical information from patients with influenza-like illness for estimation of the influenza vaccine effectiveness (VE) using the test-negative case-control design. We found that the overall VE was 59.1% (95%CI 41.1 to 71.8%) against all influenza and 53.5% (95%CI...

Update: ACIP Recommendations for the Use of Quadrivalent Live Attenuated Influenza Vaccine (LAIV4) - United States, 2018-19 Influenza Season.

Intranasally administered live attenuated influenza vaccine (LAIV) was initially licensed in the United States in 2003 as a trivalent formulation (LAIV3) (FluMist, MedImmune, LLC). Quadrivalent live attenuated influenza vaccine (LAIV4) (FluMist Quadrivalent, MedImmune) has been licensed in the United States since 2012 and was first available during the 2013-14 influenza season, replacing LAIV3. During the 2016-17 and 2017-18 influenza seasons, the Advisory Committee on Immunization Practices (ACIP) recommen...

Immune History and Influenza Vaccine Effectiveness.

The imperfect effectiveness of seasonal influenza vaccines is often blamed on antigenic mismatch, but even when the match appears good, effectiveness can be surprisingly low. Seasonal influenza vaccines also stand out for their variable effectiveness by age group from year to year and by recent vaccination status. These patterns suggest a role for immune history in influenza vaccine effectiveness, but inference is complicated by uncertainty about the contributions of bias to the estimates themselves. In thi...

Improving influenza vaccines: challenges to effective implementation.

Influenza virus causes contagious respiratory illness and remains a major burden on healthcare systems and the economy. Seasonal influenza vaccine is the most cost-effective way to combat the disease. However, underestimation of disease severity and controversy over vaccine safety and effectiveness hampers public confidence in vaccination. Action is needed to restore public confidence and improve vaccine uptake. Tailoring seasonal influenza vaccines according to immune responsiveness and infection/vaccinati...

Redefining influenza seasonality at a global scale and aligning it to the influenza vaccine manufacturing cycle: a descriptive time series analysis.

Annual seasonal influenza vaccine manufacturing cycles align with temperate country seasonality in each hemisphere, yet influenza seasonality is poorly defined for many countries. The study introduces a novel and universal approach to defining and classifying seasonality that can be used to classify any country's influenza vaccine cycle alignment.

Determinants of healthcare workers' willingness to recommend the seasonal influenza vaccine to diabetic patients: a cross-sectional survey in Ningbo, China.

Seasonal influenza vaccine uptake among diabetic patients is low in China. Recent studies showed healthcare workers'(HCWs') recommendation is an effective way to promote influenza vaccination. This study aimed to assess HCWs' willingness to recommend influenza vaccine to diabetic patients and identify the predictors of this willingness.

Evaluation of the field-protective effectiveness of seasonal influenza vaccine among Korean children aged < 5 years during the 2014-2015 and 2015-2016 influenza seasons: a cohort study.

A field effectiveness evaluation of the influenza vaccine among children younger than five years is important due to the high burden of influenza in this age group. The epidemiology of influenza virus changes rapidly each year. Moreover, the development of a new type of influenza vaccine is accelerating, necessitating a new field effectiveness evaluation.

Universal influenza vaccines: From viruses to nanoparticles.

The current seasonal influenza vaccine confers only limited protection due to waning antibodies or the antigenic shift and drift of major influenza surface antigens. A universal influenza vaccine which induces broad cross-protection against divergent influenza viruses with a comparable or better efficacy to seasonal influenza vaccines against matched strains will negate the need for an annual update of vaccine strains and protect against possible influenza pandemics. Areas covered: In this review, we summar...

Exploring the risk of severe outcomes and the role of seasonal influenza vaccination in pregnant women hospitalized with confirmed influenza, Spain, 2010/11-2015/16.

Based on previous observations during pandemics and seasonal epidemics, pregnant women are considered at risk of developing severe influenza outcomes after influenza infection. With the aim of preventing severe influenza illness, the World Health Organization (WHO) includes pregnant women as a target group for seasonal influenza vaccination. However, influenza vaccine uptake during pregnancy remains low in many countries, including Spain. The objectives of this study were to increase the evidence of pregnan...

Seasonal influenza immunisation: Strategies for older adults.

Adults over the age of 60-65 years suffer disproportionally from seasonal influenza, experiencing high rates of complications, exacerbation of underlying medical comorbidities, and excess mortality. Thus, older adults are an important priority for influenza immunisation campaigns. Unfortunately, older adults generally display lower immune responses to standard influenza vaccines because of immunosenescence, with resulting suboptimal vaccine effectiveness. Thus, the development of improved vaccines that hei...

Extending the Breadth of Influenza Vaccines: Status and Prospects for a Universal Vaccine.

Despite the widespread use of seasonal influenza vaccines, there is urgent need for a universal influenza vaccine to provide broad, long-term protection. A number of factors underpin this urgency, including threats posed by zoonotic and pandemic influenza A viruses, suboptimal effectiveness of seasonal influenza vaccines, and concerns surrounding the effects of annual vaccination. In this article, we discuss approaches that are being investigated to increase influenza vaccine breadth, which are near-term, r...

Vaccination: What's new?

Vaccination practices in Germany are driven by scientific developments and a complex regulatory environment. Some important developments in 2018 are described here: Starting in 2018 only quadrivalent influenza vaccines will be used for the seasonal vaccination. Despite the availability of meningococcus ACWY and B vaccines and their use in other countries only the type C conjugate vaccine will be used for the routine vaccination of children. For the first time there is now an official recommendation to also ...

Implementation of maternal influenza immunization in El Salvador: Experiences and lessons learned from a mixed-methods study.

The World Health Organization (WHO) recommends that countries prioritize pregnant women for influenza vaccination, yet few low- or middle-income countries (LMICs) have implemented maternal influenza immunization programs. To inform vaccine decision-making and operational planning in LMICs, there is a need to document and share experiences from countries that provide seasonal influenza vaccine to pregnant women, particularly those with high coverage, like El Salvador.

Mouse strain and sex as determinants of immune response to trivalent influenza vaccine.

The study examined the influence of sex and mouse strain on germinal center (GC) reaction and antibody responses to seasonal split trivalent influenza vaccine (TIV).

Beliefs, attitudes, and barriers associated with the uptake of the seasonal influenza vaccine among patients visiting primary healthcare clinics.

To explore beliefs, attitudes, and barriers associated with uptake of the seasonal influenza vaccine among visitors to primary healthcare clinics.

Determinants of non-vaccination against seasonal influenza.

In Canada, vaccine coverage for seasonal influenza remains below targets. Few studies have sought to determine the sociodemographic factors associated with non-vaccination using a Canada-wide survey. This study aims to identify the determinants of, and the reasons for, non-vaccination.

Forecasting demand for maternal influenza immunization in low- and lower-middle-income countries.

Immunization of pregnant women against seasonal influenza remains limited in low- and lower-middle-income countries despite being recommended by the World Health Organization (WHO). The WHO/PATH Maternal Influenza Immunization Project was created to identify and address obstacles to delivering influenza vaccines to pregnant women in low resource setting. To gain a better understanding of potential demand from this target group, we developed a model simulating pregnant women populations eligible for vaccinat...

Early bird gets the flu. What should be done about waning intraseasonal immunity against seasonal influenza?

Recently published studies highlight the growing evidence for waning immunity within a single influenza season among vaccinated individuals. However, the public health efforts to increase vaccination coverage has resulted in earlier administration of vaccines. We find this approach to be suboptimal, as the benefits of early vaccination could be lost during peak months of influenza activity. Immunity generated by influenza vaccines is a complex scientific issue with many contributing factors. We advocate for...
