With the rise of Covid-19 novel coronavirus, there's a sudden & substantive push to develop vaccine countermeasures.
One of the most hopeful areas is using mRNA, messenger RNA, to induce immunity. Properly designed, the goal is to stimulate immune response by mimicking the antigen production of viral pathogens.
Promising research includes self-amplifying RNA vaccines or replicons. A continuing challenge for replicon utilization is finding effective routes for vaccine administration (delivery barriers).
New businesses are quickly being founded / funded. Look for:
mRNA Research
Replicon Research

God Bless Us, Every One!
