WHO’s Science in 5 on COVID-19 – Vaccine trials


Episode #13

Science in 5 is WHO’s conversations in science. Watch WHO experts explain science related to COVID-19.
Learn what scientists look for in the different phases of a clinical trial for a vaccine. What does it mean when a vaccine trial is halted due to an adverse event? WHO’s Dr Kate O’Brien explains in Science in 5 this week.


  1. Vaccine is solution for disease like corona virus but vaccine is not a law or a rule for human healty the point is how we live this life with a rule also with a law prosedur becouse ignore the rule also ignore the law it will be reaction as a reason for human healty and also it will be more virus type of virus spared in this earth

  2. “COVID” Is the BIGGEST HOAX in HISTORY. IT’S TIME TO RISE UP PEOPLE! COVID = Certificate sent everyone to the supreme court Of Vaccination ID NO MORE LOCKDOWNS / NO MORE MASKS!

  3. Definition of insanity: a vaccine for a “virus” with a 99.7% survival rate. In other words, we’d be CRAZY to take this vax!

  4. Very good series of short vids to educate people. I think, WHO should do more vids like this (in all official UN languages + portugese and hindi). Some people cannot tell the difference between cure and vaccine, have no idea of how our immune system works, do not understand the basics of PPE and hygiene (touching mask outer side, no proper hand washing, not using gloves etc), many do understand antibiotics work only on bacteria and not on viri… So a set of short, on point educational videos like this one will be very useful! Thank you so much for your work!

  5. Piss off. Why do still exist? WHO have failed too many times to still justify existence. Would have fallen on my sword if I have let the world down so many times? Then again, maybe it is because Chine in tonsil deep in the WHO. Puppets!
