The co-founder of Moderna appeared on Fox News last week to speak about booster shots, saying that the vaccinated “may well need an annual booster, potentially varying on a year-to-year or every-few-years basis as the virus varies, similarly to what we do with the flu vaccine.”

That yearly boosters may be needed for the most vulnerable isn’t proof that vaccines don’t work or that we should live in fear of COVID-19. It’s a reminder that taking precautions is good, and tools are available, but a world without COVID-19 will probably not happen.
