Re: Re: Vaccine lot number information; Aventis Pasteur

[Guest guest]

King,

Attached is a Word file that characterizes the

state of vaccines in 1999, 2003, and 2006

with respecet to Thimerosal.

As far as I can ascertain, all Lederle DTaP

vaccines were Thimerosal-preserved with the

last lots being manufactured in 2002 (which

would translate to a 2007 exporation date

since Lederle appears to have assigned a

5-year expiration date at that time [the lot

expiriong in 2001 was probably made in 1996]),

the year Lederle exited the majority of its

" older " vaccines business in pursuit of the

higher profits that could be made in the

" newer " vaccines (e.g., Prevnar and, in

partnership with MedImmune at that time, the

live flu-virus vaccine, FluMist.

By 2003, the FDA was no longer listing them

as an active mfg of DTaP, influenza, etc.

Hopefully, this information will help you

all in your efforts to clarify the label

amount of Thimerosal in each dose of each

vaccine you or your child received.

Respectfully,

PS: Just because a given vaccine is not in

one of these tables does not mean none

was available for use.

This is the case because the vaccine

makers tend to assign 5-year dating to

all but their " flu " vaccines.

and all,

In general, once a drug product lot is

released into distribution, all doses of

it remain there and usable until:

a. The lot expires,

b. The lot is recalled by the maker or,

in rare cases, seized by the U.S.

government, or

c. The dosage unit is improperly stored

or contaminated.

So the answer to your first question,

>is it possible though that a vaccine

>they produced in 2002 could still be

>on the shelves and being used by

>doctors today

is " YES " -- since, as far as I have been

able to ascertain, Lederle did not recall

all in-date lots when the stopped making

a given vaccine.

Similarly, the answer to your second

question is " NO. "

The answer to your third question is that

Lederle is, and has been for about two

decades, a subsidiary operation within

what is now " Wyeth " (formerly, American

Home Products until the negative publicity

from their weight-loss combination drug

caused them to change their official name

to Wyeth in the 1990s) and has been a

subsidiary since " Wyeth " acquired what

was then American Cyanamid Company and

its Lederle pharmaceutical division in the

1980s.

As far as I can ascertain, Wyeth did not

transfer their licenses to make their " old "

vaccines that they stopped making to any

manufacturer who produces such " old "

vaccines formulations.

Hopefully, the preceding information has

adequately answered your questions, BUT,

if not, you should try contacting Wyeth

and posing these questions to them directly.

Respectfully,
