Videos Explaining Vaccines

This is simply a collection of videos on vaccines. In case you are still "doing your own research".

First: mRNA was 50 years in the making. Not just developed in less than a year:

This 12 minute video explains various processes and problems and challenges over 50 years and how these challenges were overcome.

So how does mRNA work? This video below provides a quite detailed explanation:

The next video also explains how mRNA vaccines work. In case you want a second source. (And personally, I think the video below is a little clearer and simpler than the one above.)

The next video further explains mRNA vs other types of vaccines, in particular the AstraZeneca and Johnson & Johnson vaccines which uses a harmless virus (adenovirus) as a carrier (from 5:17 in the video). At 1:15 in the video, the 4 main types of vaccines (Attenuated, Inactivated, Toxoid, Recombinant protein) are explained. At about 3:02, the typical vaccine development timeline is explained, and then at 3:22, how the Covid vaccine timeline was shortened by overlapping several phases or doing phases concurrently, rather than sequentially.

I should have open with this video. I think it explains everything quite well.

This video compilation is a resource as to the science of vaccines, and in particular the explanations for how mRNA vaccines work.

Of course, a true-blue anti-vaxxer will not be convinced by a random (or several random) videos on Youtube that contradict those random videos and articles they found on the internet that claim vaccines are poison. 

Or that the vaccines are actually "not approved", but only have "Emergency Use Authorisation" (EUA) under the US FDA. [Singapore's Health Science Authority has giving Interim Authorisation for Pfizer, Moderna, and Sinovac-Coronavac vaccines under the Pandemic Special Access Route (PSAR). 

The video below explains how EUA are given and at 2:58 in the video, how an EUA can be revoked when the drug/treatment proves to be ineffective.

And yes, fast-tracking the testing and approval process does carry some risks as this video presents:

But, while there are risks, scientists are upfront about these risks (5:50) at the testing stage. But this is a global emergency, and any time saved translates to lives saved. But before the vaccine is distributed for general use, scientist would be sure about its safety.

Anyway, if you are "doing your own research", these videos should be part of your research.
