Rapid Response:

What does failing vaccine immunity mean for current and future generations?

Joel A. Harrison says "...children under 1 year of age aren't immunized because their immune systems haven't developed to the point where they will successfully respond to a vaccine".[1]

It's my understanding children aren't generally vaccinated[2] with the MMR vaccine until one year of age, as it's expected they will have have maternally derived antibodies, i.e. passive immunity from their mother. However, it has emerged in recent times that mass vaccination with the MMR may be shortening the duration of protection by maternally derived antibodies against measles, mumps and rubella, i.e. that the children of vaccinated mothers may become vulnerable to disease sooner than those of mothers naturally infected with measles, mumps and rubella.[3]

This result of mass vaccination with the MMR may have devastating consequences for future generations, is anyone considering this?

In response to John Stone's suggestion that "many will have waning or failed immunity because of the inefficacy of the vaccine", Harrison casually suggests he "for one, would much rather get a quick jab every few years..." There are moves afoot for this in Australia, see for example: Measles vaccination program will target WA adults, PerthNow, 26 March 2019:

Is this what lies ahead of us, the community being made dependent on pharmaceutical intervention with regular live MMR revaccinations throughout life, with unknown duration of immunity, in effect stealing away from future generations the natural immunity that I and others of my generation usually garnered in childhood?

There are serious problems emerging with the use of vaccine products, and the unknown long-term cumulative effects with the ever-increasing vaccine load.

It's time to stop the polarised and antagonistic discussion on vaccination, and for independent and objective specialists to seriously consider the implications for the global community, including in regards to current vaccination schedules and the implementation of further vaccine products.

2. The correct term here is 'vaccinated', as immunisation is seldom verified.
