evidence: Table 2. People who are moderately or severely immunocompromised: Recommended COVID-19 vaccination schedule by COVID-19 vaccination history, September 6, 2024 - See footnote* for guidance on children who transition from age 4 years to age 5 years during the initial vaccination series. [...] COVID-19 vaccination will not affect the results of SARS-CoV-2 viral tests (nucleic acid amplification or antigen tests). [...] There have been rare reports of MIS-like illness after COVID-19 vaccination identified from U.S. surveillance (<1 MIS-C case per million vaccinated children without laboratory evidence of SARS-CoV-2 infection). However, the contribution of COVID-19 vaccination to an MIS-like illness is unknown.
