CDC panel recommends US seniors get souped-up flu vaccines

Americans 65 and older should get newer, souped-up flu vaccines
because regular shots don't provide them enough protection, a federal
advisory panel said Wednesday.

The panel unanimously recommended certain flu vaccines that might
offer more or longer protection for seniors, whose weakened immune
systems don't respond as well to traditional shots.

Options include: Fluzone High-Dose, Fluad with an immune booster, or
Flublok which is made with insect cells instead of chicken eggs.

Flublok [Influenza Vaccine] is a sterile, clear, colorless solution of
recombinant hemagglutinin (HA) proteins from three influenza viruses
for intramuscular injection. It contains purified HA proteins produced
in a continuous insect cell line (expresSF+) that is derived from Sf9
cells of the fall armyworm, Spodoptera frugiperda (which is related to
moths, caterpillars and butterflies), and grown in serum-free medium
composed of chemically-defined lipids, vitamins, amino acids, and
mineral salts
