Though the new study doesn't offer an explanation, De Serres said it's easy enough to guess at a number of conflating factors. "The HCWs were educated about illness before they got the vaccines," said De Serres. "Maybe they didn't come to work if they weren't feeling well." Need for good science, better flu vaccine

However, a large study (N=2215) noted that there was no difference in mortality when adding live attenuated virus to inactivated virus vaccination, AUTHORS' CONCLUSIONS: It appeared, from the limited number of RCTs we were able to include, all of which were more than a decade old, that inactivated vaccine reduced exacerbations in people with COPD.

2. In 2008, another Cochrane review [15] again concluded that “little evidence is available” that the flu No Value in any Influenza Vaccine: Cochrane Collaboration Study By: Heidi Stevenson. A remarkable study published in the Cochrane Library found no evidence of benefit for influenza vaccinations. Its also damns the quality of flu vaccine studies by stating that the vast majority of trials were inadequate. A suite of three influenza vaccine reviews has been updated: Vaccines for preventing influenza in healthy adults. Plain language summary.

Cochrane study flu vaccine

The flu vaccine doesn’t reduce deaths from pneumonia and flu. The National Vaccine Program Office, a division of the U.S. Department of Health and Human Services (HHS), funded a study 17 to examine flu mortality over the period of 33 years (1968–2001). The study found no decrease in flu mortality associated with the widespread use of the 2020 Pentagon study: Flu vaccines increase risk of coronavirus by 36% Examining non-influenza viruses specifically, the odds of coronavirus in vaccinated individuals were significantly higher when compared to unvaccinated individuals with an odds ratio (association between an exposure and an outcome) of 1.36. One kind of study would be direct inoculation of flu into volunteers who received either the vaccine or placebo. This is the simplest study to do (if you can find volunteers to get the flu) and lends biologic plausibility to the vaccine, but doesn’t reflect the real world. Flu vaccines typically contain three to four strains of the flu — two type A strains and one or two type B strains.

We identified four cluster-RCTs and one cohort study (n = 12,742) of influenza vaccination for HCWs caring for individuals ≥ 60 years in LTCIs. Four cluster RCTs (5896 residents) provided outcome data that addressed the objectives of our review.

Cochrane is a global independent network of researchers in more than 130 countries who strive to produce credible, accessible health information that is free from commercial sponsorship and other conflicts of interest. Influenza (‘flu) is an infectious disease caused by the influenza virus, of which there are several strains. The influenza vaccine works by priming the body’s immune system to recognise the molecules of the influenza virus that would normally stimulate an immune response during a natural infection.

The flu vaccine given to millions of people each year in Britain is “over-promoted” and “over-hyped” and the protection it offers against the seasonal illness has been exaggerated

The well-respected Cochrane Collaboration’s comprehensive 2010 meta-analysis of published influenza vaccine studies found that the influenza vaccination has “no effect” on hospitalization, and that Despite media reports saying a vaccine is protective, if you read the manufacturer package insert, it states, "vaccine [antibodies] have not been correlated with protection from influenza." Hmmm. That Flulaval study showed that for every 100 people vaccinated, only 3 experienced a benefit.That's a favourable vaccine study! 2020 Pentagon study: Flu vaccines increase risk of coronavirus by 36% Examining non-influenza viruses specifically, the odds of coronavirus in vaccinated individuals were significantly higher when compared to unvaccinated individuals with an odds ratio (association between an exposure and an outcome) of 1.36.

The influenza vaccine works by priming the body’s immune system to recognise the molecules of the influenza virus that would normally stimulate an immune response during a natural infection. These molecules are termed ‘antigens’.

The aim of this Cochrane Review, first published in 2007, was to summarise research on immunising healthy children up to the age of 16 with influenza vaccines during influenza seasons. We used randomised trials comparing either one of two types of vaccines with dummy vaccines or nothing. Across the UK, flu vaccination is recommended each year for all those aged 65 years or over (‘older adults’) and for pregnant women and Cochrane Reviews have examined effectiveness The ability of an intervention (for example a drug, surgery, or exercise) to produce a desired effect, such as reduce symptoms.

Millions of people suffer from pneumonia each year in varying degrees. An infection of the lungs, those with chronic lung disease and other related conditions can become very ill if they get pneumonia. For this reason, the vaccination is of

Four cluster RCTs (5896 residents) provided outcome data that addressed the objectives of our review. The studies were comparable in their study populations, intervention and outcome measures. In an accompanying commentary, Heath Kelly and Marta Valenciano write that Osterholm and colleagues used more restrictive criteria than those used by the Cochrane collaboration in recent analyses of flu vaccine benefits. The Cochrane group defined efficacy as the relative reduction in risk of symptomatic, lab-confirmed flu and defined effectiveness as protection against flu-like illness, a less specific outcome. FLU VACCINES FOR THE ELDERLY: Also an update of an older Cochrane Review (2010), Vaccines for Preventing Influenza in the Elderly looked at eight studies of over 5,000 people over the age of 65, concluding that “ Older adults receiving the influenza vaccine may have a lower risk of influenza (from 6% to 2.4%), and probably have a lower risk of influenza-like illness) compared with those who do not receive a vaccination over the course of a single influenza season (from 6% to 3.5%). Search strategy: We have used the Cochrane CF and Genetic Disorders Group specialist trials register which comprises references identified from comprehensive electronic database searches, hand searching relevant journals and abstract books of conference proceedings and communication to the drug companies marketing influenza vaccines.Date of the most recent search of the Group's specialised register: November 2001. There is currently no evidence from randomised studies that influenza vaccine given to people with cystic fibrosis is of benefit to them.
