...real vaccines not mRNA vaccines
It's hilarious how people contort themselves in fear of mRNA vaccines, when they basically avert all of the "problems" that antivaxxers dream up for traditional vaccines
Many traditional vaccines use live attenuated viruses that can themselves cause some disease symptoms and that, in VERY rare instances, can be spread (though what can be spread [the favorite antivaxx trope is "shedding"] is a super-weakened virus).
-anitivaxxers: Don't put a virus in me! I don't want to be sick!
-mRNA vaccine inventors: OK, use an mRNA vaccine, there's no virus whatsoever!
The live attenuated viruses (or viral fragments) in traditional vaccines must first be cultured in human cells (growth media). Some cell types used come from fetal tissue isolated in the 60s and cultured ever since
-anitivaxxers: Don't put aborted fetal cells in me!
-mRNA vaccine inventors: We don't use them in mRNA vaccine production, at all, because we don't need to culture a virus, at all. (And even in traditional vaccines, all growth media is rigorously removed from the vaccine anyway).
Traditional vaccines work best with adjuvants, often aluminum salts, used in small amounts.
-anitivaxxers: Don't put heavy metals in me!
-mRNA vaccine inventors: OK, we don't use them, at all. Plus... the aluminum salts are not "heavy metals" anyway, and are nontoxic at the small doses used in traditional vaccines. But if it bothers you, you must be excited about mRNA!
Vaccines before ~2000 often used preservatives, such as antibacterial compounds (thimerosal, ethyl mercury, is one)
-anitivaxxers: Don't put mercury or other preservatives in me!
-mRNA vaccine inventors: OK, we don't use them, at all. Plus... no vaccines used in the USA use thimerosal. Antibacterials are only used in vaccines intended to be distributed in remote areas with no refrigeration and when single-use vials are impractical.
mRNA vaccines ingredients
-anitivaxxers: We have no idea what's in there!
-mRNA vaccine inventors: the ingredients are simple and well-defined: saline, a trace of mRNA, a small amount of lipid (natural fats) to encapsulate / stabilize the mRNA, natural sugars, and sometimes a small amount of a solubilizing agent such as PEG or tromethamine, which have been used for decades in all sorts of injected drugs.
-antivaxxers: I don't want to change my DNA!
-those with even a 7th grade science education: please, go look up the
central dogma of biology to understand what RNA is and does and stop getting your info from youtube videos
-antivaxxers: microchips!
-sane people: Really? You think anyone cares to monitor your trips to Walmart? Think, man...
