Smallpox Vaccinations May Remain Effective for Life

 

Some 90 percent of people vaccinated for smallpox 25 to 75 years ago are still protected against the disease. Although it was formerly thought that smallpox vaccinations were only effective for three to five years, researchers found that significant immunity levels last for many decades and -- possibly for an entire lifetime.

Further, repeated vaccinations provide a boost in immunity in the short term, however they do not result in higher levels of protection over the long term. Repeated vaccinations are no more effective than a single vaccination in the long term.

Dr. Mercola''s Comments Dr. Mercola's Comments:

Looks like all the anti-terrorism protection is unnecessary. It is all a moot issue anyway as it is likely the vaccines are not necessary to avoid smallpox. If this sounds like heresy then you have likely not read why hygiene is more important than vaccination against smallpox.
