It is a nice idea, but human vaccination over the eyes is stil lnot well established, not to say a COVID-19 vaccine so far.

There is no effective vaccination against the COVID-19 not only for the eyes but for the whole body

The route of vaccination may not matter but the efficacy of the vaccine.

Thanks alot for all who reply....

What i am thinking in is to infect healthy volunteers only through their eyes with a live virus (either it is attenuated or not) and just monitor if they will develop severe symptoms or not and if their bodies develops IgM, IgG against the virus or not...

As i said i am not expert on Vaccination but It is just an idea ...

Thanks,

We must wait more than 1 year to have the opportunity to get an efficient vaccine against this virus

If I have to choose between the two, than definitely I will prefer intra nasal vaccination as it will be much easier and convenient.

vaccination is more effective against this infection but it takes long period of time
