SUMMARY

The aim of this study was therefore to analyze the association between COVID-19 related deaths and influenza vaccination rate (IVR) in elderly people worldwide.  The results showed a positive association between COVID-19 deaths and IVR of people ≥65 years-old. There is a significant increase in COVID-19 deaths from eastern to western regions in the world. Further exploration is needed to explain these findings, and additional work on this line of research may lead to prevention of deaths associated with COVID-19.

SUMMARY

Environmental factors play a critical role in the induction of autoimmunity, with an interplay between genetic susceptibility and environment. Several neurologic demyelinating diseases have been reported following vaccination, notably Guillain-Barre syndrome (GBS) and acute disseminated encephalomyelitis (ADEM) (an inflammatory disease of the central nervous system). A number of the most common vaccines appear to have some involvement with autoimmunity.

SYNOPSIS

Repeated influenza vaccination at a young age substantially increases the risk of influenza at older ages.

TITLE

Repeated influenza vaccination of healthy children and adults: borrow now, pay later?

CITATION

Carrat F, Lavenu A, Cauchemez S, Deleger S. Repeated influenza vaccination of healthy children and adults: borrow now, pay later? Epidemiology & Infection 2006;134(1):63-70.

SUMMARY

This study shows that repeated influenza vaccination at younger ages may double the risk of influenza in the elderly. The study suggests that the “possible benefits of vaccinating children after 5 years of age, and otherwise healthy adults—particularly over a long period and mainly for economic reasons—could be outweighed by severe clinical consequences and increased costs in the elderly.” Moreover, the findings are “solely due to differences between vaccine-induced immunity and naturally acquired immunity.” Unlike vaccination, naturally acquired immunity can provide long-lasting protection against subsequent infection by the same viral subtype.
