Claim 8 of 8Not checkedThe article says three-quarters of infection-related cancers came from low-income and middle-income countries, with the bulk of diagnoses in eastern Asia, and that HPV and HBV vaccination should reduce cancer rates; it also says there is still no vaccine or other way to control EBV spread and that clinical trials for EBV vaccines are underway.View evidenceHide evidence
