Why You're Not Getting Delta Specific Boosters Yet

[SeaBreeze]

Here's an article about the vaccinations and boosters, thought some folks here might want to read more details. Some of this is a bit over my head, but interesting nonetheless.

Dan Barouch, an immunologist at Beth Israel Deaconess Medical Center in Boston, reasons that delta-specific vaccines probably won’t be that much better than the original vaccines because delta’s spike protein is pretty similar to the ancestral coronavirus’s in terms of its look and shape. That means the antibodies created by the original formulation of the vaccine, if we’re given third shots of it, should work well to attack the virus.


Angela Rasmussen, a virologist at the University of Saskatchewan, agrees. “We don’t need delta-specific vaccines,” she told me. Even for the huge swathes of the world that haven’t gotten any shots yet, and that could theoretically take a delta-specific vaccine as their first dose, she’s not sure it’s worth developing that tailored vaccine. “It would take a while to get through regulatory approval and manufacture and vaccines are needed now.”

Thanks for sharing. Too deep for me.

Thank you for that good article. It does explain what I did think was the reasoning, but it's good for me to see it, there too.

My summary:
The Delta is not different enough, to require a different one, and the timing of sooner availability is more valuable.

It appears that the Moderna vaccine...which we got...is having the best results. However, if this virus continues to spread, and millions continue to ignore its consequences, we will give serious consideration to a booster if/when it becomes available in a few weeks/months.

The rush for ivermectin has 'strained the equine and livestock world'​

​

All this talk of ivermectin isn't coming at a detriment to humans alone — it could leave vulnerable animals without the proper medicine needed for care, as veterinarians, ranchers, and farmers contend with surging public demand, The New York Times reports.​

These anti-vaxxers don't want to take the covid-19 vaccine because it "hasn't been proven to be safe," yet they're taking medication designed for animals that has been proven to be unsafe for humans.

Ivermectin has been used for decades for treating malaria, but mainly for preventing it. Various drugs created for specific uses are used for other things. The term for this is "off label use" and it isn't uncommon.

An over simplification- T cell memory.

From what I heard the spike protien or mrna vaxxes don't leave a t-cell memory and t-cells are part of immune system processes. For more I'd research t-cells, immune system or natural immunity(which apparently does include t-cell memory).

That's right.

The coronavirus has 28 spike proteins. The vaccine can target one, the one that likes your lungs. Natural immunity creates T-cell memory for all 28 proteins. In either case, just like with the rhinovirus and some others, you can get sick from the coronavirus again and again.
