High time we started looking at the vaccines we might all be getting soon. I'm going off half cocked here as I'm all at sea, but we need to get the ball rolling.
The new mRNA vaccines are a bit spooky, as millions of doses may be given over the next few months under Emergency Use Authorization, without the 2 year observation period looking for possible delayed adverse events that is customary with new vaccine development. While this seems a bit ominous to me, between the Pfizer & Moderna's 74,000 trial volunteers, there really hasn't been any substantial adverse events reported that I can find. It appears these vaccines work without adjuvants, which seem to be associated with problems in other vaccines, so plus one in my book if this is true. Moderna has never brought any drug or vaccine to market before, so I'm partial to Pfizer (love their little blue pills too!)
Not sure if I've got my facts straight here, but it appears China's Sinovac, GlaxoSmithKline (GSK), & an Australian company are using SQUALENE, which caught my eye. I recall squalene adjuvanted anthrax vaccine was associated with Gulf War Syndrome (many with GWS had developed antibodies to squalene), & the squalene adjuvanted Pandemrix H1N1 flu vaccine was associated with narcolepsy in children back in 2009/2010.
Noticed it was reported: A Coronavirus Vaccine Could Kill Half A Million Sharks (squalene derived from shark livers)

Sounds like a lot of the vaccines might contain this! Will there be a new "Warp Speed Syndrome" associated with squalene adjuvented vaccines?
AstraZeneca's AZD1222 vaccine is simian adenovirus based, & I can't find an adjuvant associated with this vaccine. AZ is the one where the trial was halted due to possible association with Transverse Myelitis, & a previous issue with multiple sclerosis that was claimed to be undiagnosed before the trial. The AZ shot is the closest I've seen to traditional vaccines, so perhaps the least "experimental"?
Novavax is adjuvanted with "Matrix-M" plant based / Quillaja saponins (Chilean soapbark) formulated with cholesterol and phospholipids. Noticed Novavax is claiming less chance of Vaccine Enhanced Disease (aka ADE / antibody dependent enhancement of disease), as their immune response is Th1 dominant. Isn't the T-Cell immunity what we want for cross-immunity to mutated strains? Looks good to me! It appears this vaccine is cultured in insect (moth) cells?
Sorry if this post isn't a fount' of knowledge and lacks links & references, but I'm simply trying to stimulate some activity in this area. The big push to "get your jab" will be on sooner than we think. Don't know if we'll have much choice, but if we do, let's hope we make an informed choice.
