(Shouldn't you know how viruses mutate to jump species BEFORE spraying live mutated
virus nasal vaccines around that were cultured in companion animal cells?
Not exact matches
One reason
vaccines using weakened flu
virus are not used in the elderly is that they have been exposed to many strains of flu
virus over the years and have more antibodies in the
nasal tract, which can inhibit the weakened flu
virus from infecting and stimulating the immune response necessary to protect against the
virus.
For their research, Pekosz and his team, using human
nasal tract cells, studied the weakened strain of the flu
virus that is used in the
nasal spray
vaccine and compared its behavior with that of the flu
virus itself.
To create the weakened flu strain contained in FluMist, the brand name of the
nasal spray
vaccine, nine mutations in the flu
virus were made.
Specifically, 1 unit of access comprising a vaccination / challenge study with 3 groups of 6 ferrets (control and 2
vaccine groups), to include vaccination / boost, intra-
nasal challenge with influenza
virus, monitoring of
virus load (
nasal washes), disease progression and immune responses (antibody, IFN gamma ELISA and ELISpot).

Two
vaccines for swine flu — a
nasal spray that contains weakened
virus and a shot that contains inactivated
virus — were approved in September, but skepticism and worry about such new
vaccines may prevent people from taking advantage of them.
(Another type of flu
vaccine, administered through a
nasal spray, is made from live, weakened influenza
viruses and is not recommended for people with underlying medical conditions.)
(Pregnant women should not get the
nasal spray form of the flu
vaccine, which contains a weakened live
virus.)
The
nasal - spray version of the
vaccine, called the FluMist, (which is FDA - approved for kids and adults between ages two and 49 who are healthy and not pregnant) does contain a crippled version of live flu
virus.
Vaccination can be given in a
nasal form or in an injection (either modified live or killed
virus vaccine) given in the right shoulder area.

«
Vaccines that contain outdated strains of influenza may provide only partial clinical protection, and may result in
nasal shedding of the
virus, oftentimes as much as an unvaccinated horse, thus putting other horses at risk.»
«Ideally, horses will develop antibodies against the relevant
vaccine strain, resulting in a significant reduction of clinical disease and
nasal shedding of the
virus,» points out Hancock.
However, the
viruses contained in the
nasal - spray flu
vaccine are attenuated (weakened), which means they can not cause flu illness.
