I am so grateful to have heard your podcast with Dr. Hyman and have such a balanced and objective point of view shared. I have spent weeks researching this and your information is the best source I have found from a layperson point of view who really does try to look at all sides. Can you share further info on two items please?

1. More info on preventing the virus from jumping to the bloodstream and how this works-The vaccines DO offer "disease immunity" in which the virus will be prevented from jumping to the bloodstream due to the production of neutralizing antibodies. This reduces the chance the disease will have severe effects on the vascular system and major internal organs.

2. From the podcast - more info on the 4 pillars you mentioned on herd immunity. Everything I see online mention only 1-2 pillars of the 4 that you said need to be in place. If I understand herd immunity correctly, you stated on Dr. Hyman's podcast there are 4 factors to achieve it. 1. A vaccine that confers sterilizing immunity (these covid vaccines are all non-sterilizing) 2. In the case of covid's infectious rate - 90% of population vaccinated with a sterilizing vaccine (based on the more infectious the disease, the higher that percentage is. The actual formula is one minus one over R-nought) 3. Durable lifetime immune protection. 4. the virus needs to not have an animal reservoir. Could you provide more study material on the difference between 1 and 3 and more info on 4? I am so appreciative to your work and perspective. Many thanks

Hello Dale,

I know there are still a lot of unknowns, but I was wondering if you could expand a little more on whether or not those who had a prior covid infection with the virus still need to get vaccinated in order to achieve the full vaccine compliance (>80%)? If those who already had the infection and did not have serious illness, would it still be necessary to vaccinate since it's not going to change transmission rate and their immune system already cleared the virus once without issues? Thank you!

Hi Dale, - Why does the CDC have comments about achieving herd immunity, along with the press discussing this if herd immunity is not achievable with an animal reservoir? If I understood from the Doctor's Pharmacy podcast the 4 pillars you mentioned on herd immunity, covid can reach none of these. Everything I see online mentions only 1-2 pillars of the 4 that you said need to be in place. If I understand correctly, you stated on Dr. Hyman's podcast there are 4 factors to achieve it. 1. A vaccine that confers sterilizing immunity (these covid vaccines are all non-sterilizing) 2. In the case of covid's infectious rate - 90% of population vaccinated with a sterilizing vaccine (based on the more infectious the disease, the higher that percentage is. The actual formula is one minus one over R-nought) 3. Durable lifetime immune protection. 4. the virus needs to not have an animal reservoir.

Could you provide more study material on the difference between 1 and 3 and more info on 4?

Is the press and CDC using the term herd immunity to apply to pillar #2 independently (which I think is misleading, because it gives the impression that herd immunity can be achieved if we can just get enough people vaccinated). This too can wrongly influence people's behaviors after the vaccine. Here is the quote from the CDC's page answering the question. "Experts do not yet know what percentage of people would need to get vaccinated to achieve herd immunity to COVID-19. Herd immunity means that enough people in a community are protected from getting a disease because they’ve already had the disease or they’ve been vaccinated. Herd immunity makes it hard for the disease to spread from person to person, and it even protects those who cannot be vaccinated, like newborns. The percentage of people who need to have protection in order to achieve herd immunity varies by disease. CDC and other experts are studying herd immunity and will provide more information as it is available."

Can you provide a link to a resource that helps me understand the 4 pillars needed for herd immunity that you mention? Thank you for your time and invaluable information.
