Does anyone have information if this was ever peer reviewed?
This shows results for ~ 48 transgenic mice. I would say that, at the time, the vaccine reported in the press release from Pfizer had a 99% chance of being approved by FDA, while this vaccine has maybe a 10% chance of being approved by the FDA at best.
If you’re one of the top pharmaceutical companies in the world, some press releases and study protocols are simply not enough [1] and should be (imo) discarded.
If you’re a new player (Vaxxas) claiming “complete protection” by testing your product on mice, it’s simply not enough and should be (imo) discarded.

> The University of Texas Hexapro vaccine candidate – delivered via the UQ-developed and Vaxxas-commercialised high-density microarray patch (HD-MAP) – provided protection against COVID-19 disease with a single, pain-free ‘click’ from a pocket-sized applicator.

You can probably only make them take it when you ground the pill up in their BBQ sauce or Kale juice or something similar...
(This is hilarious and so obviously a counterintel campaign, the FBI and others have a history[1] and mandate of infiltrating groups and steering them into compliance with more absurd information
Only a small portion of them are nutjobs and most are just unnecessarily cautious.
Along those lines, some other interesting companies in early stages are:
* Inovio - skin-based, but with a special device - https://www.inovio.com/our-focus-serving-patients/covid-19/
* Vaxart - oral pill - https://www.pharmaceutical-technology.com/news/vaxart-vaccin..., https://vaxart.com/tablet-vaccines/
* ImmunityBio - oral/sublingual/subcutaneous injection/combo - https://immunitybio.com/covid-19/, https://www.globenewswire.com/news-release/2021/01/12/215692... (some of their papers also compare against intramuscular versions of their drug, but they appear to want to avoid big needles and have some means of injecting just below the skin, but not as shallow as this HD-MAP approach it seems)
* Oravax Medical - oral - https://www.webmd.com/vaccines/covid-19-vaccine/news/2021032... / https://www.ora-vax.com
* Aeterna Zentaris - oral - https://www.zentaris.com/oral-coronavirus-vaccine, but this is still pre-clinical.
This site https://covid-19tracker.milkeninstitute.org/#vaccines_intro also mentions two other oral-based companies, but either they don't have any explicit info on progress or they haven't been mentioned since early 2020:
- Applied Biotechnology Institute - http://www.appliedbiotech.org/research-development/products-...
- Migal Galilee Research Institute - https://www.migal.org.il/en/coronavirus-vaccine-project, https://www.timesofisrael.com/israeli-made-oral-vaccine-for-... (since the main website still says in-vivo in 90 days, I'm guessing there was a halt in development.)
If the Milken Institute is up-to-date, Inovio should be furthest along (prepping phase 3), followed by ImmunityBio (phase 1/2). Anyone succeeding would be a wonderful addition for the world!
She managed to go over her fear for the COVID-19 vaccine, but it took her a lot of effort to get there.

That is a paper about the patch. It's an array of 3,000 micro-needles. The needles are coated with dry vaccine. The needles destroy many cells during application, which increases the body's immune response and uptake of the vaccine.
The dry vaccines do not spoil as easily as the liquid ones. I recall seeing injections of dry medicine powder many years ago in rural West Africa. The nurse first used a sterile syringe to draw sterile water from a vial, injected it into a new medicine vial, withdrew the syringe, shook the vial and let it sit for a minute, and then drew the liquid medicine suspension and injected it into the patient.
Are any injectable covid vaccines distributed as dry powder?
Was looking into Pfizer’s effectiveness against the Indian variant since that seemed to be the most worrisome one out there and this was the vaccine I got.
What it boils down to: 1 shot + 3 weeks: 33% effective. 2 shots + 2 weeks: 88% effective.

Happy to have gotten both shots of Pfizer as overkill looks like exactly the right amount of kill. If I can get boosters down the line in the form of a patch, all the better really.
> The HD-MAP is a 1 x 1 cm solid polymer microprojection array containing 5,000 projections of 250 μm in length. Vaccine is coated onto the microprojections via a nitrogen-jet-based drying process before application to the skin at a velocity of 18-20 m/s via a spring-loaded applicator.
> Here, we explore HD-MAP delivery of a subunit vaccine candidate –a recombinant SARS-CoV-2 spike glycoprotein, termed HexaPro which has been stabilized in its prefusion conformation by removal of the furin cleavage site and the inclusion of six stabilizing proline mutations
Schools can be considered continuous super-spreader events.
Kids weren’t even shown to be to be too infectious.
No vaccine is 100% safe, it’s very possible the risks of vaccinating kids outweighs the rewards.
Is the virus 100% safe? Weigh them against each other and account for who the kids could spread it to, how much vaccine uptake there is, immune compromised they could spread it to who can't be protected well from the vaccine, etc.
Where is the data to support this? Duke University released a peer reviewed study[1] in January that showed the opposite (when schools take appropriate measures).
> Duke and UNC researchers evaluated the secondary transmission of COVID-19 in 11 North Carolina school districts that held in-person instruction in the first nine weeks of the 2020-2021 school year and identified minimal COVID-19 transmission in the schools -- much lower than the rate of community spread.
The CDC have also published this[2] helpful overview about the susceptibility of children to the virus/disease (low) and the risk of transmission (also low).
I'd also urge you (or anyone) to read this very helpful article in the BMJ[3] about the risks of covid-19, but for those worried about their children it may help alleviate some concerns:
> The second row of table 2 shows that three deaths from covid-19 have been recorded among over 7 million schoolchildren aged 5 to 14 (around 1 in 2.4 million), an extremely low risk that represents only 2% of the average normal risk faced by this group. This amounts to around two days’ extra risk of dying during the 112 days of the epidemic. In the same period this age group experienced 138 deaths from other causes.
The CDC report gives a clue as to where the focus should be:
> Underlying medical conditions are also more commonly reported among children who are hospitalized or admitted to an ICU
In short, schools aren't providing super-spreader events.

We don’t go back to normal when the earth is a sterile disease free environment, we go back when the outsized risk of this particular disease reduces to the noise floor of everything else.

I don't know how likely either of these scenarios is. But it seems like leaving kids unvax'd allows a possible reservoir of virus that could resurface and affect people.
At this point there's a substantial chunk of the US population hellbent on demonstrating the lockdowns and vaccines and everything that's been done throughout 2020 was completely unnecessary, by simply continuing to do nothing. They will never take a vaccine, they'll risk getting sick and let the natural immunity unfold. They're more concerned with overturning the 2020 election results.
