Informed Consent for 4th dose

Protection by a Fourth Dose of BNT162b2 against Omicron in Israel

January 2, 2022, Israel, fourth dose of BNT162b2 to over 60s

Effect on infection and severe coronavirus disease


Israeli Ministry of Health database

1,252,331 over 60s eligible for the fourth dose

Omicron predominant, (January 10 through March 2, 2022)

Confirmed infection and severe Covid-19

Starting at 8 days after receipt of a fourth dose, (four-dose group)

Compared with (three-dose group)

Received a fourth dose 3 to 7 days earlier (internal control group)


Number of cases of severe Covid-19 per 100,000 person-days

Four dose group, 1.5
Three dose group, 3.9
Internal control group, 4.2

Adjusted rate of severe Covid-19

January 10, 2022, to March 2, 2022

In the fourth week after receipt of the fourth dose

Four dose group, lower than that in the three-dose group by a factor of 3.5

Four dose group, lower than that in the internal control group by a factor of 2.3

Protection against severe illness did not wane during the 6 weeks after receipt of the fourth dose.

The number of cases of confirmed infection per 100,000 person-days (unadjusted rate)

Four dose group, 177

Three dose group, 361

Internal control group, 388

Confirmed infection in the fourth week

January 10, 2022, to March 2, 2022

Four dose group, lower than that in the three-dose group by a factor of 2.0

Four dose group, lower than that in the internal control group by a factor of 1.8

However, this protection waned in later weeks.


Rates of confirmed SARS-CoV-2 infection and severe Covid-19 were lower after a fourth dose of BNT162b2 vaccine than after only three doses.

Protection against confirmed infection appeared short-lived, whereas protection against severe illness did not wane during the study period.

We excluded the following persons from the analysis

those who had had a confirmed SARS-CoV-2 infection before the beginning of the study,

So this tells us nothing about the effect of natural immunity

Please can we have data on vaccine induced immunity

versus natural infection induced immunity


Efficacy of fourth dose versus two or three dose hybrid immunity

  1. Thank you John I appreciate everything you do to get good information on the booster shot verses natural immunity I'm 62 and going to pass on the booster shot this time I've got my school age granddaughter living with me avoided getting C- 19 for two years and when they lowered restrictions we got sick me worse than her of course so if it's not going to give much protection why get it
    I am completely vaccinated with moderna but got sick before I could get booster shot I also had flu and pneumonia shot but I have COPD and got C-19 pneumonia and unwell for 2 months so I think 3rd shot of moderna yes but not 4th does but may in the fall

  2. How can we support a 4 vaccine dosis in a short period of time? This seems criminal. They continue to talk about vaccine dosis, but nothing about medical treatment unless some new very expensive pills.

  3. Who is going to inform the people about the vaccination doses. Why everyone is trying to cheat the common man and making MONEY out of this virus. We have become the scapegoats of medical fraternity and pharma companies. Please try to educate people,so that we can save our near and dear from these vaccine.

  4. Can we have a video (forgive me if it has been discussed) that gives your perspective on Pfizer’s usage of relative risk reduction vs absolute risk reduction as well as the data leading to people concluding there is now an immunodeficiency syndrome on the back of being triple jabbed for example?

  5. Nobody in their right mind would take any of these injections. The data is steadily mounting against the very first dose, let alone a 4th. With an ARR of 0.84% it's been a waste of time from the very beginning and inferior to natural immunity – even (secretly) acknowledged by Pfizer way back. Herd immunity can't be reached by these injections. They are NOT vaccines. Who doesn't get that yet. People who are considering a 4th dose have got greater problems that what they think they have. It's making things worse. Stop it!

  6. I would recommend that everyone should read 'The Truth about Drug Companies' by Maria Angell MD, published way back in 2004. You'll be surprised how prescient it was, and how little has changed in the eighteen years since then.
    Also try 'Selling Sickness' by Ray Moynihan and Alan Cassels, published in 2005.
    And 'Big Pharma' (How the world's biggest drug companies control illness) by Jacky Law, published in 2006.
    A pharmaceutical company executive once famously said that his dream was to sell a medication to healthy people. I.e., so that everybody in the world, sick or healthy would buy his product. The vaccines are that dream realised: marketed to everybody, ill or well alike.

  7. Thank you Dr. John Campbell. I agree about your comments about hybrid immunity plus vaccine. My mom is 81, got Covid before there was a vaccine and she already got 3 doses. Family tried to push for 4th doses. I am against it. Also, I heard that Pfizer is coming out the vaccine for Omicron so I felt that we can skip the 4th dose and go straight to the 5th dose. Your thoughts?

  8. John, when are you going to link the repeated doses and destruction of the type 1 interferon response (ie damage to your primary immune system.) Also any info on the explosion in HIV?

  9. Ive had 2 belts of covid, never coughed so much in all my life. didn't go for vacs/ but will admit I suffered from after effects e.g. shortness of breath, but after 6-7 months it went. clear as a bell now
    I think the choice is down to the individual; and their should be no malice. and I still congratulate DR J. Cambpell for all the work he has contributed to the general public.

  10. I have just had my 4th jab (over 75 booster) after watching this presentation. I have one question. At the clinic, I was asked whether I had had Covid in the last four months, to which I replied: not that I was aware of. If I actually have had non-symptomatic Omicron, or whatever, will today's injection have put me at risk in any way?

  11. Got JnJ vaccine on 9/3/21. The next day I had tingling in extremities . Spread throughout my body. Over that week I had muscle spasms, tinnitus, BP and HR spikes, couldn't urinate couldn't defecate, eyes burn n vision gets blurry. I feel Inoxicated at times (like cannabis high), and my heart does not act the same. It hurts sometimes. Sometimes a stinging, a stabbinga, a pressure, sometimes it quivers feels like it stops for a second then shakes back to rhythm and when it does that I feel waves of heat though my limbs. Had covid a month after this vaccine nightmare and let me tell you… It made these vaccine symptoms 100000000 times worse. I would hear voices at night. Have brain and body zaps trying to fall asleep. I'd sometimes feel this stinging sensation travel from my left shoulder down to my left hand. Even as I type this I feel this buzzy vibration like sensation in my arms n chest n face w some muscle spasms in my legs. No Dr will listen to me and just say I'm stressed or anxious. I'm pretty sure my body is constantly producing SOME sort of chemical in excess. I've heard histamine, I've heard autoantibodies. I really don't know. But that's just what it feels like. I wake up in the morning and once my bod comes out of that relaxed state I feel something bgin moving though my body. Causes burning and tinittus blurry vision and inflammation. It's all in God's hands, whether I live or die, I know it will be ok, because God has me. I just wish I didn't let my emotions get the better of me on that day…. That fatefully day of September 3rd… Recently passed my 7 month mark….

  12. I have been and remain a big fan of Dr John and this program for over a year now….BUT quite disappointed in this one – in particular as it relates to the title. Perhaps it should have just been entitled, "An Honest Assessment of the Benefit Side of the 4th Dose". But it is not at all a legit discussion on 'Informed Consent' if there is no mention of the very real (and not insignificant) risk of adverse events from the jabs.

  13. I've had no jabs and although I tested positive on LFTest in Feb I felt like I had mild cold. didn't need time off work. working from home anyway. I keep hearing people say they would have got it much worse if they hadn't had the jabs but that's but my experience seems to be different. my husband is same. we both just had mild colds. we have no pre existing conditions.

  14. No more for me ,had the first two doses mainly due to family pressure , the much heralded and highly propagandarised Covid jabs have in reality been as useful as a chocolate teapot.


  16. Can't think of another reason why the infectivity rate increases in the first week after being vaxxed? It has been widely recognised that after ANY vax for the first 1-2 weeks your immune system is effectively lowered and you are more vulnerable to any illness you come in contact with. I'm fairly sure he's mentioned that fact in previous episodes and specifically in relation to these jibby jabs. Now, with specific evidence by way of "the control group", it is suddenly a mystery? I can only hope he is couching what he says this way, because he has what he deams more important information to impart and trying to fly below the "fact checking " radar.

  17. I live in the UK and recently took my 89 year old mother to get her fourth dose. On your advice I mentioned to her to ask them to aspirate. They flatly refused saying, 'we don't need to do that, we've never done that, it's not necessary as the injection goes into the muscle not the blood vessel'. It's pretty shocking really. Considering she asked for it would it really be out of their remit to just do it? Why all the arguments over what is such a small thing (for them) but such an important thing? I wonder if the UK will ever change their guidelines to realise the importance of aspiration?
