Second Dose of Varicella Vaccine May Be Needed to Prevent School Outbreaks

NEW YORK (Reuters Health) Jun 16 - One dose of varicella vaccine may be
insufficient to prevent school outbreaks of chickenpox, according to a
report in the June issue of Pediatrics.

Outbreaks of varicella continue to be reported, even in highly vaccinated
populations, the authors explain.

In Arkansas, a varicella vaccination requirement for entry into kindergarten
was introduced in 2000, so by September 2003 children in kindergarten
through third grade 3 were covered. Nonetheless, a large number of cases of
chickenpox occurred in an elementary school in 2003. Dr. Sandra L. Snow from
the Arkansas Department of Health, Little Rock, and colleagues investigated
the outbreak. (...)

Kommentar von Barbara Loe Fisher, NVIC:

"Forty-three of 48 students (90%) who developed varicella had been
vaccinated, the findings indicate, and the highest attack rate occurred in a
first grade classroom where all of the students had been vaccinated."

In 1995, when the FDA licensed Merck's live varicella zoster vaccine, the
AAP denied that the vaccine for chicken pox would be mandated. Anybody who
knew anything about mass vaccination policies in America knew that was not
true. Every vaccine which has been recommended by the CDC for universal use
in children during the past 50 years has eventually been mandated.

In 1995, the National Vaccine Information Center opposed mandated use of
chicken pox vaccine because (1) the vaccine was known to be only 80 percent
effective; (2) the disease was mild for 99.9 percent of children with most
children obtaining a qualitatively superior immunity that lasted a lifetime;
and (3) because mandates would take chicken pox out of the normal childhood
population, where it was primarily benign, and drive it into older adult
populations where it can cause severe complications.

Sure enough, the AAP was not telling the truth in 1995 and eventually the
AAP and CDC both lobbied with Merck for state mandates. Today almost all
states mandate chicken pox vaccine for school entry.

As a result of a decade of mass vaccination of all American children with
chicken pox vaccine, there are (1) serious reactions (brain inflammation and
death) from the vaccine; (2) transmission of vaccine strain chicken pox to
vaccinated and unvaccinated children; (3) an epidemic of shingles in adults
because older children and adults no longer have their immunity
asymptomatically boosted by coming into contact with young children with
chicken pox.

Now a study confirms that lots of vaccinated kids are coming down with
chicken pox anyway. No surprise here - the vaccine was never more than 80
percent effective in preventing chicken pox. So what do the experts suggest?
Why more chicken pox vaccine of course! Another booster dose that will boost
the numbers of vaccine reactions and chronic immune system dysfunction of
vulnerable children as well as boost the profits of Merck.

No vaccine delivers lifelong immunity. All vaccines carry an inherent risk
of injury or death. Vaccine consumers are always taking two risks: the risk
of a vaccine reaction and the risk of vaccine failure to protect.

On the other hand, Mother Nature usually gets it right the first time.
