@pathforward327 @jwarrenreincarn @BrighamWomens The US has less government in healthcare than any other developed nation. We also have the most problems in healthcare, spend the most, and get the least for our money. It’s almost like when all parties are trying to maximally extract $ from the patient, that has an impact.

@caitlinmoriah Absolutely. This attitude of “*I* alone did it, *I* am amazing, and *I* can make you amazing too” is absolutely baffling to me. Highlighting their own “greatness” and not the people who helped lift them up along the way is an immediate turn off for me.

Data on cancer incidence and death rates through 2021. COVID vaccines had EUA in 12/2020. No uptick in cancer incidence or death. No “turbo cancer” (a made up term that doesn’t exist). Antivaxxers get it wrong yet again.

@jakeshieldsajj No, a bivalent vaccine is replacing the monovalent vaccine. That means it covers 2 strains now instead of just 1. The “half amount” is just the standard booster dose for Moderna. Pfizer’s dose is unchanged.
