There are human and non-human viruses in nature. Some infect people others infect animals. Some have the capability to infect both. As an example, a bird virus may directly infect humans or it may be inefficient and not highly infectious If that bird virus infected a pig, who can also have a human strain, they may exchange genetic material and properties to create a new strain which is efficient. Humans would not have any immunity to the new strain and it could hold the potential for a pandemic. As a new strain, it could take several months to develop and produce a specific vaccine for that strain, leaving people without immune protection.
