The efficacy (prevention of illness among vaccinated persons in controlled trials) and effectiveness (prevention of illness in vaccinated populations) of influenza vaccines depends on several factors. The age and immune status of the recipient are important as well as the match between circulating viral strains and the vaccine. Randomised controlled trials comparing vaccinated with unvaccinated participants show that outcome measures that include laboratory-confirmed infection with influenza virus provide the most robust evidence of vaccine efficacy.
Health Officials in the UK have admitted that flu strain that is sweeping the planet this year, H3N2, is barely affected by the vaccination that is meant to prevent it. Only 3 out of every 100 vaccinated people are prevented from getting full-blown influenza, a situation that has led to a large rise in the elderly winter death rate in the UK.
This shows the uselessness of the World Health Organization system of deciding year ahead which flu strains will be circulating the following winter. One of those strains, the one that happens to be causing most illness this year, has mutated so significantly that the vaccine is ineffective against it.
The strain, H3N2 causes major respiratory issues in the elderly and those with medical problems, it also happens to be the strain that is dominant in Canada and the USA this year.
The CDC is recommending prompt treatment with anti-viral …
New legislation proposed in the California Senate would outlaw waivers that allow parents to exempt their children from receiving basic vaccinations for religious or personal reasons.
The bill is a response to the latest measles outbreak in the state.The bill, announced Wednesday, would require all children to receive vaccinations prior to attending public school in the state. The proposal allows for exemptions only in cases where a pre-existing medical condition would prevent a vaccination. Schools, meanwhile, would have to make their vaccination rates public.
Make their vaccination rates public…lets hope they make public the number of children sickened, disabled or killed by vaccines as well.
Although older people may have a reduced immune response to influenza vaccine compared with younger adults, they may still benefit from influenza vaccination. Older people are more likely to have a condition that places them at higher risk of complications from influenza. However, it is also important to vaccinate those in close contact with elderly and individuals at high risk of influenza infections to reduce the spread to those who are more vulnerable and also may be less likely to mount a strong immune response to the vaccine.
