>>13812104Moderna has more than 3x the amount of mRNA material per dose (100 microgram instead of 30). Moderna has subsequently shown higher myocarditis cases, most particularly in males under 30. This is ironic given that this is also the age group least at risk to the virus itself.
The chief epidemiologist of Iceland completely banned the application of Moderna (in favor of using Pfizer) for this reason. Also Norway, Sweden, Denmark and Finland have restricted its use in men or people under the ages of 18 or 30 in favor of Pfizer.
The problem is that Pfizer is shown to wear off faster, such that after six months the case rate is the same regardless of whether or not you had the vaccine, thus "fully vaccinated" individuals from Pfizer who do not receive additional booster shots are spreading the disease, especially the Delta variant. This is regardless of whatever the CDC tells you - they work with predetermined conclusions that it is effective regardless of the facts. However, the country of Israel used exclusively Pfizer, and it turns out that after six months they discovered in their data that the rate of "breakthrough" cases was matching the vaccination rate. So, Israel simply made their vaccine passports expire after six months, requiring booster shots.

J&J and Astrazeneca have shown other adverse reactions not present in the double-shot mRNA treatments - I don't call them vaccines. These two, J&J and Astrazeneca, not only have shown more adverse reactions, but they also have literal aborted and/or monkey fetal cell lines in them.
