Why does this (vaccine development) take so long?
As mentioned above, there are currently no approved human coronavirus vaccines
In addition, many technologies used (production platforms, vectors etc.)are new & need to be tested thoroughly for safety.

@match_joe @CharlesTannock
This article also provides quite a handy overview of the various drugs and vaccines being tested.

How CV19 Could Take Over Your Body

This is essential reading as science writer, Jeff Wise spells out the journey of CV19 through the air & into & thro’ bodies explicitly & (too?!) colourfully.

Social distancing takes on a colourful meaning, Tim Martin nymag.com/intelligencer/…
It starts off like a normal day in Covidland
You try to be good, decide to meet a fried outdoors.
Used hand sanitiser
Keep a distance.

But, unknown your friend’s Dad had contracted COVID 10 days ago.

When your friend, his son was visiting, the Dad, breathed in 32456 particles
Altho’ it transmits in droplets & other waste, it aerosols eg when coughed out before settling on surfaces.

So the virus makes its way inside your friends body, multiplying ever since. Virus-ladened droplets wafts over your table & settle on your uneaten food.

312405 particles

Chinese studies: CV19 sheds virus particulars for 20 days, both transmitting pre and post symptoms, suggesting quarantine periods may need to be longer raising new containment challenges.

Ingrained hand washing & hygiene measures particularly important.

scmp.com/news/china/soc…
Answering one of my questions, it seems that those given anti viral medication, did not reduce the period of the virus shedding.

This may mean that anti virals should be administered for longer.
It is estimated that 44% of transmissions occur before the infected person displays symptoms.

Contact tracing and isolation alone unlikely to be successful at containment, hence the need for social distancing an excellent hygiene

Lessons learned from South Korea — Outbreak Observatory

Also a reminder that by far the largest group testing positive for #CV were in the 20-29 age group (& linked to the Shincheongi religious community.

Next largest 50-59 yr old.
outbreakobservatory.org/outbreakthursd…
It is therefore a very different demographic to Italy. BUT South Korea learned from the hard experience of MERS in 2015 where they realised they had to contain the spread early on and that needed both diagnostic testing and systematic tracing plus quarantine

And they were ready
Not only had they had a very hard experience from MERS but that led to a systematic review and action plan ready should another such outbreak occur. It felt real.
And they tested it.

And corrected it

And realised in December that neighbouring China might have something similar

I am not hysterical or fearful when it comes to #CoronaVirus. What I am “Truly” Concerned About & Afraid of: is “How” the Powers & Governments Can Utilize & Use it- and the “Things” they can Do to us Utilizing it. Does That Make Sense?
#CoronaVirus: The Timing of it makes me think. The Reaction & Associated Actions to it Make me think Twice and Harder. And the possible “Man-Made” (Non-Organic) consequences and results make me highly concerned. Hope you catch my drift.

Thread: #Vaccines 💉

This is one of the hardest subjects to #RedPill people on.

If you've trusted me up to this point, please trust me enough to research what I've written.

Vaccines were my red pill, I've spent a lot of time digging into them. I know the truth.
↙⬇↘
The biggest argument by anti-vaxxers is choice. Vaccines shouldn't be mandatory. In some places they are & they want to make them mandatory nationwide.

No one should be forced to do something to themselves or their kids that they don't want to do.

Choice is a freedom!
↙⬇↘
People are told that we need to have herd immunity, so everyone needs to be vaccinated.

Time to use both critical & logical thinking.

If vaccines work, shouldn't a vaccinated person be protected?

How does exposure to a disease make a vaccine less effective?
