I wouldn't count on it. I have been doing ten to fifteen stings every other day (weekends off so three days a week) for over two years to treat Lyme and Carrion's disease plus all of my antibiotics. Not the mention the stings I get when working hives. I still get sick and I am still battling Lyme and Carrion's. Not saying it isn't helping but it certainly hasn't made me immune to disease. The only thing I can say for sure is it has really scarred my back where my wife stings me. There's a similar thread on a Lyme forum I belong to saying maybe Lyme patients don't get covid19 or maybe our treatments protect us to some degree. I think it's just wishful thinking.

Bee venom has antiviral properties. It doesn't guarantee immunity against viruses but does offer some protection. If ever I start feeling sick I eat propolis as well. I too is has antiviral properties.
It's a bit difficult to extract their methods in the paper, but apparently they sprayed a mixture of bee venom and flu virus into mice noses. The mice that got the bee venom mixed with the flu survived and those that got straight flu up the nose died.
No mention of testing bee venom via stings.
So, we know that as a nasal spray, it seems to work, at least in mice. Problem is that most of my bee venom is sub-Q or IM. Some of the bees have what seem like really long stingers!
Thankfully, the bees are smarter than I am. They are doing well, in spite of my efforts to help them.
If bees stings help a person fight of COVID-19, I should be good to go. I was inoculated about 5 times today. Oh, and my wife and I have not left our property in 15 days now. Not that there's anything unusual in that.
Good Luck everyone
