Home / Ask The Experts / My moderately immunocompromised patient is unvaccinated against COVID-19 and has agreed to receive a primary series. Since a dose of mRNA COVID-19 vaccine may be given up to 4 days before the recommended interval because of the 4-day grace period, should we offer appointments up to 4 days before the recommended interval to get him vaccinated faster?

Scheduling Vaccines

My moderately immunocompromised patient is unvaccinated against COVID-19 and has agreed to receive a primary series. Since a dose of mRNA COVID-19 vaccine may be given up to 4 days before the recommended interval because of the 4-day grace period, should we offer appointments up to 4 days before the recommended interval to get him vaccinated faster?

No. People should not be routinely scheduled to receive a dose earlier than recommended. Schedulers should offer appointments beginning on the date of the recommended interval or later. CDC guidance allows for doses to be given up to 4 days before the recommended interval in order to avoid missed vaccination opportunities when a recipient unexpectedly arrives early and might not return on schedule.
