infectious diseases and treatment of cancer since its use for the eradication of smallpox.
However, the current method of editing the VACV genome is not efficient. Here, we
demonstrate that the CRISPR-Cas9 system can be used to edit the VACV genome rapidly
and efficiently. Additionally, a set of 8,964 computationally designed unique guide RNAs
(gRNAs) targeting all VACV genes will be valuable for the study of VACV gene functions.
