Dear Talha Bin Emran ,a very interesting question, that viruses originating from animals must be fought with viruses from other animals as well, it feels like that, but so far there are no articles or information that specifically discuss this, including in Indonesia. Hope that someday it can be realized, maybe the current experiment hasn't led there yet. Best regards.

Both a live and an inactivated rabies virus containing the SARS-CoV-2 spike S1 protein induces potent virus-neutralizing antibodies at much higher levels than seen in the sera of convalescent patients.

Im not sure about that. but maybe swine can be useful.

Dear Talha Bin Emran , Warm regards, We all act in the scientific realm with full experiments in stages, maybe one day there is a vaccine derived from animals to cripple this covid virus, but it takes hard work to prove the truth. like snake venom made from other snake venom as an antidote, I myself tried it in 2006 and it worked. Scientists work with limitations, but their steps clearly lead to "asked questions" but until now the scientist's work has not achieved what was intended. Unless something magical happens.
