The safety experience with AFLURIA (trivalent
formulation) is relevant to AFLURIA QUADRIVALENT because both vaccines are manufactured using the same process and have overlapping compositions:
Thus, the concept of hensitivity is trivalent
. One is hensitive toward x if one possesses the feature H, unhensitive if one possesses its anti-feature NH, and neither if one lacks both.
In response to global reports of B lineage mismatch and the hypothesis that quadrivalent vaccine may reduce the burden of influenza disease compared with trivalent
vaccine, for the first time in the 2012-2013 Northern Hemisphere influenza season, the WHO influenza forecast included an influenza B strain from each of the influenza B lineages.
Bivalent OPV consists of live, weakened poliovirus strains of type 1 and type 3, and is considered at least 30% more effective than trivalent
Muscat: Health officials are gearing up to switch from a trivalent
to a bivalent polio vaccine from April 27.
OPV contains live and weakened versions for all the three types ( 1, 2 and 3) of wild polio while the bivalent vaccine will contain type 1 and 3.
(2014) Effectiveness of seasonal trivalent
inactivated influenza vaccine in preventing influenza hospitalisations and primary care visits in Auckland, New Zealand, in 2013.
Influenza vaccines contain either 3 or 4 antigens (trivalent
or quadrivalent) and either inactivated or modified live viruses (inactivated influenza vaccine [IIV]) or live attenuated influenza vaccine [LAIV]).
* A high-dose trivalent
shot approved for people 65 and over.
With the exceptions of trivalent
recombinant influenza vaccine (RIV3 [FluBlok], Protein Sciences) and cell culture-based inactivated influenza vaccine (ccIIV3 [Flucelvax], Novartis), currently available influenza vaccines are prepared by propagation of virus in embryonated chicken eggs.
The process comprises separating chromium from the sludge by selectively oxidizing the trivalent
chromium precipitate to soluble hexavalent chromium with chlorine gas in alkaline medium.
