This idea of switches that are part of our immune system, that we might be able to control someday, should have very interesting and useful benefits in the future. We talked about Cancer above and of course the research on that is far from complete.
Going back to Covid-19, there was an interesting observation during the AstraZeneca trials that I can't seem to shake out of my mind. It could just be clinical trial error. It could be laboratory noise. Or it could be quite significant. It was the observation of efficacy, within 3 groups of participants. Within the entire group, AstraZeneca says that their vaccine is 70% effective. Within the group that actually represents the majority of participants AND is what we plan to implement, their efficacy is said to be around 62%. That group got 2 full doses of vaccine between 4 and 12 weeks apart.
The really interesting observation was with 3,000 participants that accidently only received 1/2 the recommended dose for their 1st dose and the full dose for their 2nd dose. They had an efficacy rate of 90%. So what might be going on here. Unfortuneately, whatever one surmises with this, it will unfortuneately be an unproven theory, because we actually do not know. I would have thought that all the body should need is one big whack of covid-19 to wake it up and get it's immune system to respond with the full power of its entire capabilities. But is that what should always happen?
If a military threat came from an unknown enemy towards the US, would they really activate every single soldier. Every single Navy ship. Put every fighter jet and bomber they have into the air, and put all nuclear stations and subs on alert, no matter what the size that threat actually is? Of course not. That actually would put them at a disadvantage in many ways. They would respond with the minimum force they need to be absolutely positive of eliminating the threat at hand. This response would get activated by different military commands. Lets call them switches. Kind of like defcon 1 and defcon 2.
Our immune systems would have some of the same issues the military would have. Is Covid-19 the only possible threat going on, that our bodies are concerned with, on a given day? Of course not. Can one immune response possibly get in the way of the other. Kind of like a runway being bogged down with planes carrying infantry and therefore restricting the ability for fighter planes to land so they can to be armed and put into action. Basically, the infantry is getting in the way of the air force.
It's possible that our immune system, not only has an on and off switch depending on whether an invader is perceived to be a threat or not, but also that it might even have a different switch depending on what level of threat it perceives the invader to be. If it is a lower level threat, like a low dose of Covid-19, it might switch on its 1st immune response. If it is seen as a higher threat, like a much higher dose of Covid-19, it might switch on another level of response.
So think about this. When we give a person a big dose of covid-19 vaccine, the body sees this as a big threat and implements a higher level response. Since most higher level responses take a little longer to organize and get going, this can have some negative implications to your outcome. What you really want to do, is implement your response in the proper stages. Perhaps the 1/2 dose followed by a full dose, gets all the switches activated. Low, medium, and high and whatever else there might be. Low probably being quicker but less effective and high being more effective but a little slower to get going. Not much different then our military. Combined, however, you probably get the best and quickest total response against a new infection of Covid-19.
Some trial volunteers were given shots half the planned strength, so how does that affect the results?
