No, it hasn't. Ignoring the political organizational doings and actions such as travel shutdowns:
I was going to complete the month of March, but this post is long enough already. I picked non-vaccine-related items from https://www.gopbriefingroom.com/index.php/topic,395099.msg2169385.html#msg2169385 , https://www.gopbriefingroom.com/index.php/topic,412484.0.html , and https://www.gopbriefingroom.com/index.php/topic,412485.0.html . I also could have found relevant non-vaccine-related items from my threads about ventilators, PPE, and uses of the DPA. Just because the MSM gave it little or no coverage does not mean it didn't happen.
Very well, point made.
There were treatment options bandied about, so long as Donald Trump did not mention them.
Monoclonal antibodies and Remdesivir were two I distinctly recall being pushed, then ...crickets....
I notice you left out the Zelenko protocol being announced, explained, and then rapidly censored (I admit to being unsure of those dates) and the jihad against hydroxychloroquine, UV treatment, and others, but that's okay.
The media were hell-bent on discrediting treatments that were not hideously expensive and largely of questionable efficacy, as was the medical establishment in the spotlight--if it was inexpensive, available, and would stop the panic, it got short shrift or attacked.
The focus seemed on inciting and maintaining levels of panic in the general public that Richard Adams described in Watership Down
as going "tharn".
(This was essential in the grand scheme of things to push for voting by remote means, usually mail or drop boxes, which enabled the Steal of 2020. Whether by accident or design, this was panic was maintained and fully exploited. It was also important to impose the draconian measures which devastated the "Trump" economy, and that, too, was done--and still is.)
Eventually, the vaccine was seen as the only panacea, and any discussion of preemptive treatments (early onset, which were not hideously expensive) pretty much fell by the wayside, unles you were paying attention to the Aussies using Ivermectin (another antiparasitic, and an ionophore) with doxycycline and zinc.
The problem here is that people were told to get tested (day 4 or 5 of the disease, symptoms appear), and to wait (isolate) for results. The more delayed the results, the more severe the disease by the time they were confirmed, the worse off the patient was.
Instead, Zelenko advocated the administration of the three part protocol of Hydroxychloroquine (primarily and ionophore to get zinc into the Type 1 Pneumocytes the disease targets) an antibiotic (azithromycin, a macrolide antibiotic which not only protects against bacterial infection, but has the idiopathic effect of toning down the immune response to prevent a cytokine event) and zinc, the ion that interferes with viral replication in the cells. In the event the patient tested negative, no harm was likely, and some resistance was provided--the protocol has a prophylactic effect as well--and in the event they were positive, recovery (without needing hospitalization) was accelerated. Very few patients who followed this protocol were hospitalized.
You'd think the medical establishment would have been ecstatic (and some were, but were as quickly censored as Zelenko's YouTube, which laid out the pharmacological strategy, described in near layman's terms how it worked, what each part of the protocol did, and gave dosages he had used in practice. Nope. He got 'cancelled', using poorly conducted studies as "evidence" to justify that cancellation. Now, he has been nominated (not awarded as previously reported) for a Nobel.
