CDC guidelines shorten time between 3rd dose of COVID vaccine, reminder for immunocompromised patients – NBC Chicago

According to revised guidelines from the Centers for Disease Control and Prevention, the recommended waiting time between booster shots for “moderately to severely” immunocompromised patients has been shortened from five months to three months.

The new recommendation, released Friday at a meeting of the CDC’s advisory committee on vaccination, aims to “clarify” the booster schedule for patients with underlying conditions that make them immunocompromised.

Currently, these patients should receive three doses, instead of two, of the Pfizer-BioNTech or Moderna COVID vaccine. These patients were then to receive a booster dose at least five months after this third dose.

Under the new guidelines, these patients should now receive a booster dose at least three months after the third dose of their mRNA COVID vaccine, according to the CDC.

The change is due to “concern about initial immune response and loss of protection over time,” according to the CDC slideshow.

Small studies have shown that immunocompromised patients have a stronger immune response when they receive a fourth dose about three months after the third dose of the vaccine, according to CDC researchers.

Moderately to severely immunocompromised patients who received the single-dose Johnson & Johnson vaccine were initially recommended to receive a booster dose two months after their initial dose according to previous guidelines.

Under the revised guidelines, patients are now advised to receive a second dose of the Johnson & Johnson vaccine at least 28 days after the initial dose, with a third dose then recommended two months after the booster.
