The Latest: Does it matter which vaccine you get?

Dear Reader,

A quick Q&A: What happens if there are multiple vaccines with varying effectiveness?

In a recent modeling study, researchers argue that in most pandemic situations you should give people whatever vaccines are available even if there are efficacy differences. Vaccinating people with whichever vaccine is available will prevent hospitalizations and health care costs. While some Covid-19 vaccines might have higher reported efficacy rates than others, overall, the currently available vaccines and vaccines that may be approved for use (such as Johnson & Johnson’s) all look effective and safe.
