Corona cure..?? I guess through the "Contagion"

Most countries use an injection vaccine (syringe).

but I saw the pandemic movie "Contagion". This movie is very similar to the current situation.

in the moive, the solution was a vaccine to insert into the nose.

I agree with this way because it was transmitted through the respiratory system.

The existing vaccines are excellent. Still, i think the final solution is a respiratory vaccinne.
