Vidqun, I might have been incorrect in thinking that the Moderna Covid-19 vaccine contains graphene. I say that because the CDC at https://www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/Moderna.html#ingredients in their "Full list of ingredients" for that vaccine doesn't list graphene, at least not by that name. See also https://www.fda.gov/media/144638/download . There the FDA lists the ingredients and there it doesn't list graphene either.
I put much more confidence in the FDA information (even more when also confirmed by fact checking of news agencies I consider to be highly reliable in their reporting) about the ingredients in the vaccines than I do in the clams of some conspiracy blog about the same substances.
The FDA at https://www.fda.gov/emergency-preparedness-and-response/coronavirus-disease-2019-covid-19/moderna-covid-19-vaccine-frequently-asked-questions under the heading of "Q: What data did the FDA evaluate in support of the emergency use authorization of Moderna COVID-19 Vaccine for individuals 18 years of age and older?" says "Based on the scientific evidence available, the FDA concluded that the known and potential benefits of a two-dose primary series of the Moderna COVID-19 Vaccine outweigh the known and potential risks for people 18 years of age and older." On the same web page the FDA says "There is no scientific evidence to suggest that the vaccine could cause infertility in women."
It is true that the manufacturers of the vaccines are the ones who test them and report their safety data to the FDA, but that is because all manufacturers (at least to my knowledge) of drugs/medications are required by the FDA to test their products and report the safety data to the FDA.
