Moderna booster confusion clarified by El Paso County Health


COLORADO SPRINGS, Colo. — A couple in Colorado Springs recently received their Moderna booster shots, but in the paperwork they received afterwards, it looked as though the amount of booster they received – was wrong. And both received different dosage amounts than the other.

Concerned they weren’t being fully protected from COVID-19, they reached out to FOX21 News to get some clarification.

“After she got her shot, we looked at the receipt and it said that she got .25 and she was curious about that,” Per-Magnus Persson said of his wife, Rochelle. “She asked if she could get a full dose or whatever she was supposed to get, but the pharmacist said this is what we’ve been told to give by corporate.”

And the El Paso County Health Department confirmed the dosing was correct. They said the Moderna booster is measured out differently for those who are immune-compromised than those who are not.

“If you are immune-compromised you will get a full .5 third dose if you are not immune-compromised and it’s been longer than six months then you will get the .25, that half dose for your third dose,” Immunization Program Manager for El Paso County Health Kristi Durbin said.

Durbin said the Moderna booster is the only booster that will dose in differing amounts. The Pfizer and Johnson & Johnson vaccine boosters will each contain the full dose – the same as was administered in the initial vaccine shot series – regardless of underlying health conditions.

“It has to do with the immune response that you have to Moderna. So, the data is showing that you don’t need the full dose for that third dose if you are not immune-compromised,” Durbin added.

The Perssons, who were concerned they might need an additional booster, say more people should be made aware of the differences in the Moderna booster.

“It would be a concern to everyone, especially since nobody was informed of this,” Persson said. “We just found out on our own.”

Anyone who is 65 years and older can now receive their booster after waiting six months or more from their initial series of shots. Anyone 18 years and older can also receive a booster if they live in long-term care, have underlying medical conditions, and/or work and live in high-risk such as schools or hospitals.
