Flu Vaccine Efficacy During the Current Season
Flu vaccine efficacy has been known to decrease over the years. Research in both Canada and the United States shows that receiving the flu vaccine several times in a row can reduce the effectiveness of the vaccine records. While there does exist some degree of variation among children, adults, and babies, the overall vaccination rate remains high.
Number of Children Deaths
Recently, a study was published from the United Kingdom that showed an alarming increase in the number of deaths among children who were vaccinated against the 2009 H1N1 swine flu strain. With this increase came a significant increase in the number of reported cases of paralysis and encephalitis. This paper discusses the study conducted by a group of British scientists known as the Working Group for Health Services Research. They did a meta-analysis comparing the effectiveness of the three major influenza vaccination campaigns that are administered in the United Kingdom. Their analysis showed that, overall, there was an increasing lack of flu vaccine efficacy.
Three influenza vaccine
In the United States, the results for the three influenza vaccine programs studied by the Working Group for Health Services Research were also poor. The researchers look at data from vaccinating children in Scotland, England, and Wales who are followed up six months later. Of the vaccinated children, eight children died from the flu; interestingly, none of the children who died had received either one or two doses of the flu vaccine.
Flu risks increase why?
While most of the studies on flu vaccines were performs between the months of December and March. The flu risks increase exponentially in the months of May and June. There are also statistical trends of increased flu vaccine efficacy in children. This enrolled in the United Kingdom between December and March. However, they report no significant difference in vaccinated children being sick with the virus during the three months of June. Interestingly enough, in July, there was a significant increase in the number of sick children, but the number of deaths did not increase. So it appears that vaccinated children were not sicker than un-vaccinated children.
Working Group for Health Services Research
It should note that while the Working Group for Health Services Research performs these tests. The Department of Health in Britain also conducted their own tests using their NHS Trust. Both sets of tests found similar results in regards to overall flu vaccine efficacy. However, a major sticking point was determining if children who did not receive the full course of the recommended vaccinations would indeed become ill. The tests showed that in the vaccinated group, there was a significantly lower rate of serious adverse events (SAE). They also found that the number of cases of infections and complications did not differ much between vaccinated and unvaccinated children.
Protect people against all types of seasonal flu
Based on the data, the Working Group for Health Services Research recommends that all children immunize each year starting at age six months old and that a booster shot adds at age six months every year. However, immunizations should not be stopped due to any adverse reaction unless the doctor considers that it is necessary. The current season considers being an optimum time to protect people against all types of seasonal flu. So vaccination highly recommends during this period. There are no new findings to report, it appears that the British flu vaccination program is very effective. While reassuringly not as effective last year.

Are there advantages of Fluzone High-Dose Quadrivalen contrasted with standard portion occasional influenza immunizations for grown-ups 65 years and more established?
Information from clinical preliminaries looking at Fluzone (a trivalent standard portion immunization) to Fluzone. High-Dose (a trivalent high-portion immunization) among people matured 65 years and more seasoned show. That a more grounded resistant reaction (i.e., higher counteracting agent levels) happens after inoculation with Fluzone High-Dose.
An examination distributed in the New England Journal of Medicine external symbol demonstrated that the high-portion antibody was 24%. More successful in forestalling influenza in grown-ups 65 years and more established comparative with a standard-portion immunization.
Another examination distributes in The Lancet Respiratory Medicineexternal symbol detail that Fluzone High-portion related with a lower danger of emergency. Clinic affirmations contrasted and standard-portion Fluzone in grown-ups 65 years and more seasoned, particularly those living in long haul care offices. This examination was led during the 2013-14 influenza season among in excess of 38,000 occupants of 823 nursing homes in 38 states.
For the 2020-21 season, trivalent Fluzone High-Dose will supplant by Fluzone High-Dose Quadrivalent. Information looking at the viability of Fluzone High-Dose Quadrivalent with standard-portion inactivated antibodies are not yet accessible.
