A second dose of the two-shot mRNA vaccine like that produced by Pfizer and Moderna may not even be necessary in children who had covid. Since February, Israel’s Health Ministry has been recommending that anyone, adult or adolescent, who has recovered from covid-19 receive a only single mRNA vaccine dose, instead of two. Even though the risk of severe illness during a reinfection is exceedingly low, some data has demonstrated a slight benefit to one dose in this situation. The United States could adopt this strategy now as a reasonable next step in transitioning from an overly rigid to a more flexible vaccine requirement policy. For comparison, the CDC has long recommended that kids do not get the chickenpox vaccine if they had chickenpox infection in the past.
