There already exists such a nasal spray vaccine for influenza. And there is some hope for developing something like this for the common cold in the long run.
I have translated another part of the podcast mentioned above, about this subtopic:
“Christian Drosten: There are vaccines where this is already being done. For example, there is a nasal spray vaccine for influenza that can also be used in Germany. That is coming more and more. These mucous membranes, these nasal spray vaccines, are always genetically modified vaccines, i.e. carrier virus vaccines. This has not yet been recognized by the regulatory authorities long enough for it to be safe. Fifteen years ago, there were still great reservations about this, and today, with the increasing success of these carrier virus vaccines, especially in this SARS2 pandemic, these carrier virus vaccines are already quite successful in clinical trials. In the case of Ebola, they have been very successful. And now that more such good experiences are being made, it is to be hoped that more nasal spray vaccines will soon be available. And of course, this is then possibly also as an entry into a cold vaccination in the future. With the many cold viruses that we have, more than 15 viruses that can be listed, we may at some point come to a situation where we have nasal spray vaccines against almost all of them, especially for the adult population. So I think it is not unwise for the children to go through these harmless infections for certain immunological reasons. But for the adults these infections are in some cases anything but harmless. One has to imagine for the economy how many days of sick leave in an economy are caused by the whole bouquet of cold viruses every year. If one could vaccinate against them, that would be an incredible success.”

Cool! Thanks!
