Question explored with the scientific record

Is DIPG a rare side effect of any Covid 19 vaccines what about in any of the product monographshave dipg rates increased in the last 5 years

Sep 22, 2026 · 11 sources used · OpenNeedle synthesis
No evidence in the retrieved records shows DIPG as a side effect of any COVID-19 vaccine, and no product monographs are discussed.

The retrieved studies do not mention DIPG in connection with any COVID-19 vaccine. One study reports two cases of hematologic malignancies (lymphomas) diagnosed shortly after mRNA vaccination [1], and another describes a brain lesion called cytotoxic lesions of the corpus callosum (CLOCC) after a third dose [2]. Neither is DIPG. The records also contain no product monographs for any COVID-19 vaccine, so nothing in this retrieval speaks to what those documents list.

On whether DIPG rates have increased in the last five years, the evidence is silent. The retrieved studies cover DIPG treatment and biology [3, 4, 5, 6, 7, 8, 9, 10, 11], but none track population incidence over time. One study established the International DIPG Registry, which enrolled 670 patients as of 2017 [9], but that is a count of enrolled cases, not a population rate. Without a study comparing DIPG incidence before and after 2020, this retrieval cannot answer whether rates have changed.

My call: the retrieved evidence does not support a link between COVID-19 vaccines and DIPG, and it provides no data on whether DIPG rates have risen. Confidence: not clear.
