1. Once antibodies gone after over 7 weeks what is likely effect of reinfection, my estimate with myself is 5% of original and expect next reinfection could be 5% of 5%

10. Question? how long will coronavirus 19 last? Answer.. not long,it was made in China.

11. Corona Virus: Im killing you all!

    Chosen Ones: Psalm 91:7-16

    7.A thousand may fall at your side,And ten thousand at your right hand;But it shall not come near you.
    8. Only with your eyes shall you look,
    And see the reward of the wicked.
    9 .Because you have made the Lord, who is my refuge,
    Even the Most High, your dwelling place,
    10 No evil shall befall you,
    Nor shall any plague come near your dwelling

12. Some errors: Innate / Specific (aquired immunity ), always requires previous exposure, to the pathogen: … not true… example: Maternal antibodies imparting immunity to an infant

    Internal tissues are completely sterile… “ Zero viruses’’………not true:
    Many people have Herpes viruses in their nerve cells , such as in sacral root ganglia Herpes simplex virus (HSV) . Herpes Zoster, another common neurotropic virus, which establishes lifelong latent infections in the neurons of dorsal root ganglia.

    Measles virus can remain dormant in the brain for years, then cause a devastating brain illness and death, subacute sclerosing panencephalitis (SSPE).

    Not to mention prions

    'Malaria as endemic disease like the flu '/ Not true, since Malaria is really a zoonosis, mosquito borne protozoan. There is no human to human transmission ( except rarely by transfusion). If mosquitoes bites are prevented, humans would not get malaria. So to call Malaria endemic is inaccurate.

13. Dr. Campbell I have a question: I have a respiratory decease, will a pneumonia vaccine help me fight Covid 19

19. This is BEYOND wrong!

    "Infection means the presence of microorganisms in the tissues of the body. So normally the tissues of the body are supposed to be sterile; absolutely no bacteria no viral particles at all, just completely sterile." (0:16)

    CA monitoring 8400 people; 33 confirmed and 5 moved; claims only a few hundred tests—when x-rays and ct scan are acceptable diagnostic tools; DOZENS OF STAFFERS AT THE HOSPITAL (UCDavis) WHO TREATED THE North Cali untraceable CASE are being monitored for symptoms!

25. Dr. Campbell is boring……and very informative. Thank you. I started watching everyday this month because of the coronavirus. Your videos have become an addiction.

26. I hope there are relatively few people following this man who are in the business of discrediting his knowledge, I haven't heard him professing to be anything that he is not.

    As posted by himself.

27. Thank you Dr. that was perfect.

28. in thelocal news here in New Zealand it was said that a japanese woman who recovered from the virus is now sick again. Is this an issue?

29. I’m sorry Doc but this R0 number must be nonsense . Now there is a teacher that came back from northern Italy and ignored self isolation advice and went back to school on Monday ….fell ill yesterday . There are 2000 kids at that school and they run 11 primary school and another 2000 child secondary schools …….I work there sometimes . He should be sacked . That’s 13 schools and at least 5000 kids put at risk. Results come back today . 🤦‍♂️

30. This sounds like freaking doctor Mengele here people. Don’t listen to this.
    No part of the human body is completely sterile. We have bacteria and viruses in us and around us constantly.This is normal. Google it yourself.
    And when you’re at it you can dig into what oscillating O2 molecules does to the oxygen uptake in the lungs.

31. What about people who vape? Could an infected person become a super spreader, by leaving little clouds of virus where ever they go?

32. Thank You Dr. Campbell For The Great Insight And Allowing Us To Comprehend Terminology And Their Meanings. (New Subscriber)

33. Dr. Campbell how long can COVID-19 survive when it is outside the host?? Is it measured in hours or days??

34. Endless fear porn hype propaganda BS … This is coming to an end. It never got close to the fatality of influenza. The hyperbole has been more sickening than the virus : ( The hyperbole has been more sickening than the virus : (

    Additionally sickening – people trying to make a financial killing off the tragedy … You will never see me requesting PayPal / FundMe / … payment. I work for the good of humanity for free; because I love life. And I've been right so far; because no agenda.

    Fact – influenza is far more dangerous – 600,000 deaths worldwide every year. Get real. Follow real facts / evidence. Ignore the doomsday fanatics !
