SARS-CoV-2 variants continue to emerge. One variant, B.1.1.7, should become the dominant SARS-CoV-2 virus in the USA by March.
The appearance of variants has raised questions about how the pandemic has progressed, including whether it will affect the effectiveness of the vaccine. We asked Tina Q. Tan, MD, Professor of Pediatrics at Northwestern University’s Feinberg School of Medicine and Pediatric Infectious Disease Doctor at Lurie Children’s Hospital in Chicago in case SARS-CoV-2 variants could affect MIS-C severity.

The short answer is we don’t know. I think it would be interesting if there was a way to go back and examine children with MIS-C who were previously diagnosed with COVID-19 and see if any of these infections were caused by these variants.
From what we see now, there seem to be more cases of MIS-C. Whether that’s because it’s being detected more often or because the number of cases is actually increasing, I don’t think anyone knows.
I think it’s a bit early to say whether or not MIS-C cases caused by variants are different, and whether one variant causes more severe disease than others as this is post-infectious inflammatory syndrome too appears to be meaning that the individual does not have an acute COVID-19 but has developed inflammation 2 to 6 weeks after an acute COVID-19 infection.
