CDC says 4th COVID-19 booster dose may be needed for immunocompromised people

The U.S. Centers for Disease Control and Prevention (CDC) said in updated COVID-19 guidelines this week that some immunocompromised people may need a fourth dose of the vaccine.

The agency wrote that people who are over 18 years old who already received an mRNA COVID-19 vaccine primary series and received an additional mRNA vaccine dose may receive a single COVID-19 booster dose – Pfizer/BioNTech, Moderna or Johnson & Johnson – at least six months following their third mRNA vaccine dose.

“In such situations, people who are moderately and severely immunocompromised may receive a total of four COVID-19 vaccine doses,” the CDC wrote.

Those who have received two doses of an mRNA vaccine and are moderately or severely immunocompromised, with more than 28 days having passed since the second dose, should receive an additional mRNA dose immediately followed around six months later by a single COVID-19 vaccine booster dose.

People who are over 18, are moderately and severely immunocompromised and have received a single dose Johnson & Johnson COVID-19 vaccine primary series should receive a single Johnson & Johnson, Pfizer/BioNTech or Moderna COVID-19 booster vaccine at least two months after receiving their initial primary dose. – READ MORE
