Last spring people were turning down the Moderna COVID-19 vaccine because they thought the Pfizer-Biotech vaccine was better. Fun fact: no. A recent study suggests that Moderna may actually be a bit more effective, though the reason—differences in which populations were vaccinated with which vaccines, Moderna’s larger and more spaced-out doses—hasn’t been nailed down. Thing is, both vaccines are more than good enough, and at a population level (which is the level at which public health operates, but is hard for individuals to relate to) we’re much better off having more vaccines in more arms than better vaccines in fewer arms—especially if the differences are this slight.

Full disclosure: I got the Moderna vaccine, and I refuse to be smug about it; it’s what was available.
