COVID-19 and Childhood Cancer Vaccine Working Group

The Vaccine Working Group is a collaboration between St. Jude and SIOP.

COVID-19 Vaccine


In less than one year since the announcement of the SARS-CoV-2 pandemic, hundreds of vaccines have been developed, several of them reaching approval and usage around the world, including U.S. FDA emergency use authorization of the Pfizer/BioNTech vaccine for those age 12 and older.


The similarity of these vaccines is to produce antibodies to protect against COVID-19 infection, but each of these vaccines have different designs, compositions, number of doses, time intervals between dose administration, and efficacy.


An avalanche of information has been generated surrounding these vaccines. And to make it more challenging, a horde of misinformation disseminated with similar speed. Therefore, it is natural that caregivers and health care providers face the difficult task to make the decision whether or not to vaccinate these at-risk children.
