  1. Thank you for your continued dedication to educating others! I subscribed when I was studying to be an EMT. It's been a long time since then, & yet I still enjoy learning from you.

  2. Isn’t that what we wanted… ~ 75% herd immunity? The original lockdowns were “to slow the spread” as to not overwhelm unprepared hospitals… not to stop it. Variants- Don’t all viruses mutate? Are there more cases of [SARS C0V-2] due to more testing? How many “positives” actually have the illness [C0V-19] and what potential co-morbidity do patients have? Thank You. Be a healthy host. Peace.

  3. All of the UNVACCINATED cased – did they have covid before or is this the FIRST TIME they have been infected? Please help us understand why a vaccine is necessary if you have antibodies.

  4. Why is Georgia not tracking the Delta variant? We have had a surge or new cases again but many Georgians are still not vaccinated and going without a masks. Georgia is going to have an up-surge and the reality of this variant is going to hit them. Yet many will deny that they have covid or got it again.

    My second thought: Fun how many people hate on these companies for the vaccines but depend on them for other life saving medicines. The misinformation that is out there is really sad. I can not even get my children to get vaccinated because of the misinformation that is in Texas. All I can do at this point is hope and pray.

  5. You should get an award for providing scientific based information on Covid 19 throughout the pandemic!! YouTube should be highlighting the 'best' information and downgrading the non scientific.

  6. Thank you Doctor I truly enjoy your videos, after I took the Moderna Vaccine ala Dodger Stadium, I lost my sense of Smell/Taste. Would it be reasonable to say I will regain most or hopefully all of my Sense of Smell/Taste after time or would there be a regime one can take to help? My concern is I can not smell gas leaks or any harmful chemicals, not even Mold/Mildew.

  7. May I conclude that the efficacy of the vaccine is confirmed by studying the known exposure of vaccinated people in a specific number of people studied?

  8. It is so good to see you back! Thank you for your hard work. One slight correction, if I may: delta variant was likely, in part, a cause of India’s surge, rather than a result of it. I tracked cases in Indian States in March and April ‘21, and noticed the pattern of spread. Eventually, genomic sequencing identified the new variant.

  9. Thanks s lot! Nice to see hear you again. In Moscow delta came 6 weeks ago. Very rapidly. First time we had 19 y.o. boy in our ICU who died ((( Be safe!

  10. Which vaccine is more appropriate for persons who have already had COVID-19? What level of immunity do they have against COVID re- infections and or the delta variant? I feel that Gregg Abbott dropped the mask requirements too early in Texas-

  11. i love watching you and have learned to much. Please can you tel me if you suggest getting vaccinated
    if you have already had covid?

  12. As always, thanks so much for this latest video – good to see you! Due to the increase of the Delta variant and possible wave in the fall, could you please tell us your protocol now for yourself after having been vaccinated? I had been following your protocol in the early days of the pandemic for Nac, Vitamin D, Quercetin, zinc, etc. but after being fully vaccinated, I stopped all except continuing Vitamin D. Personally, I don’t trust non vaccinated folks to wear masks following the guidelines so I still wear a mask indoors in public. Thanks very much, and stay safe!

  13. Is there any data on those that received AstraZeneca as the first dose and Pfizer or moderna as the second dose. Many Canadians (including myself) are in this position and are not recognized as being fully vaccinated by (for example) cruise lines and countries. Wondering if we will require further mRNA doses.

  14. Pfizer and Moderna look like they use spike proteins to block the Ace2 receptors into the lungs/aveoli.
    This is the same as what vitamin D3 does, would you agree

  15. Thank you for reminding us that a strong immune system is the best medicine reduce stress,plenty of sleep healthy food and joy in your lives…have a blessed day…

  16. Thank you very much for taking the time to share the information you have thus far on covid-19 & vaccines.
    It was clear, concise & perfect for the layman & i look forward to further briefings on the subject.
