minus-squaree0qdk@reddthat.comlinkfedilinkarrow-up25·23 days agoYes. There are virus vector vaccines already in existence: https://en.wikipedia.org/wiki/Viral_vector_vaccine For example, adenovirus vector vaccines were created for COVID-19: https://en.wikipedia.org/wiki/COVID-19_vaccine#Adenovirus_vector_vaccines Those are non-replicating though. Live attenuated vaccines also exist – which can replicate – but those work by using a weakened/modified version of the original harmful live virus the vaccine is intended to protect against: https://en.wikipedia.org/wiki/Attenuated_vaccine Oral polio vaccine is a well-known example.
