H1N1 flu vaccine—why the delay?

October 18, 2019


Clearly, the vaccine production
technologies need to continue to improve. We’re still using eggs. We’re still using technologies that have been around
for a long time. We did not cut any corners
in terms of vaccine safety. All of the safeguards
are being used. We’re using the same
production methods, the same factories,
the same companies, the same safeguards
to make a vaccine that’s been used for
hundreds of millions of doses with an excellent safety record. NARRATOR: Influenza
vaccine production begins as early as 9 months before
vaccine becomes available. Each production cycle begins by selecting the strains
that are the best match to the flu strains
anticipated to be circulating during the upcoming
flu season. Mass production of each
of the virus strains occurs from January to July. Each of the vaccine strains
is produced separately by injecting live virus into millions
of fertilized hens’ eggs. The manufacturers
then begin putting doses into vials, syringes,
or nasal sprayers while waiting for FDA approval
to release lots. However, each lot
must be approved separately for release by the FDA
prior to shipment. Manufacturers and the FDA test vaccine at multiple stages
of production to ensure it is safe
and ready for shipping. It’s challenging
with a limited amount of vaccine for a lot of people
who want to get vaccinated. This means that
asking your provider, checking
with your health department, checking on flu.gov
may be necessary, whereas we wish that it would be
easier for people to find out where they could easily
get vaccinated.

    We the People refuse this with extreme prejudice, and refuse to continue to seed terror and lies into a world burgeoning with peace and brotherly love.
