It's expensive, though the price is constantly dropping, so that shouldn't be an issue later.

It still uses amniotic fluid ( I think it's either amniotic fluid or the embryo, correct me if I'm wrong) from cows, which is an issue because it still requires cows. This can be overcome by finding a way of synthesizing the amniotic fluid.

Another huge hurtle to overcome is public perception. A lot of people think it's gross or "unnatural".

I'm really rooting for it though. It needs to happen to lower methane emissions. I'm obviously not the OP and am by no means an expert. I just read a lot about it because it excites me.

Not OP, but there was a large scale study in Spain that indicates that 10% of people lose antibodies after two weeks and 74% after three months... Due to the magic number for herd immunity being around 60%... It's not likely unless around that number of the population, plus an additional number to make up for the 10% who lose antibodies quickly, all got it at the same time.

This study, however, didn't not test or examine for reinfection rates, so there may be other factors not addressed.

Do you have to clean the spores out? Or leave them as is?

Well, this has been a scam tactic since time immemorial.

"You don't have time to read it! Hurry up and sign!"

"Hurry up and give me your banking details, the deal only lasts for today!"

Yeah, that's why they made sure to mention that it did not test for immunity/or reinfection and that there are other factors. Another study says that there are potent memory b cells. The problem is that there are so many unknowns and new organizations leap on any shred of news and report it before it can be verified.
