I hear your frustration and I understand it.
I believe they are not only on track for June 30th but are, in fact, ahead of schedule now.
How fast will they get through the FDA? Well, a lot faster than getting an (actual) drug with toxicity concerns or a vaccine through.
People keep thinking in term of "Years" of testing as with a cancer or other drug to treat a longer term disease.
Flu's etc.have a short term cycle and would have tests measured in weeks not years.
Everything I've learned and heard is telling me that this is the year they hit the ground running.
