Amid a spike in COVID-19 infections caused by the omicron strain, the CDC (U.S. Centers for Disease Control and Prevention, a federal agency of the U.S. Department of Health) has recommended shortening the revaccination period. Americans who have received two doses of Pfizer vaccine are now encouraged to revaccinate five months after completing the initial vaccination course, instead of waiting six months, as stated in previous recommendations. This was reported by The New York Times.
The agency also recommended using a third dose of the vaccine for the initial vaccination, which should be given to immunocompromised children aged 5 to 11 years 28 days after the second injection (second dose), in line with recommendations for people 12 years and older. We are talking about vaccination with Pfizer. So far, it is the only vaccine approved for children in the United States.
For Johnson & Johnson and Moderna vaccines, the regulator’s recommendations have not changed: Re-vaccinations after receiving the Moderna vaccine are performed 6 months after the completion of the initial two-dose vaccination. Re-administration of Johnson & Johnson (one dose) is recommended 2 months after the first administration.
