NEW ULM — After a thorough evaluation of the latest safety and effectiveness data, the Centers for Disease Control and Prevention updated its COVID-19 vaccine interval guidance Feb. 22.

This updated guidance is specific to the mRNA (Pfizer and Moderna) COVID-19 vaccine primary series and is only for some patients who are not yet fully vaccinated.

Studies have shown that by extending the interval between the first and second dose of a mRNA COVID-19 vaccine, like Pfizer or Moderna, the risk of myocarditis (an inflammation of the heart muscle) may be reduced in addition to building stronger immune and vaccine effectiveness.

People ages 12-64 who are not moderately or severely immunocompromised — particularly males in that age range — might benefit from getting the second vaccine dose eight weeks after their first dose, instead of after the previously authorized three-week (Pfizer) or four-week (Moderna) interval.

The previous guidance between the first and second doses remains the recommended interval for people who are moderately or severely immunocompromised, adults ages 65 years and older and others with increased concern about community transmission or risk of severe disease.

The interval between COVID-19 mRNA vaccine doses is best determined by considering the balance of risks and benefits, based on an individual’s age and health conditions. If you have questions about the correct interval for you, reach out to your healthcare provider for guidance.

Regardless of the interval between the first and second dose, data show mRNA vaccines remain highly effective at reducing the risk of hospitalization or serious complications from COVID-19 infection.

People who have already completed their mRNA COVID-19 vaccine series are not affected by this updated guidance.

Remaining up-to-date with the COVID-19 vaccine by receiving a booster dose is the best way to protect yourself and others in your community against COVID-19.

For those who have an immunocompromising condition, an additional dose and a booster dose may be recommended.

Severe illness, hospitalization and death have been shown to decrease with an up-to-date vaccination.
