COVID-19 immunity may gather strength with more time between vaccination and infection; people who’ve had the virus benefit even from delayed vaccination.

Immunity. they are all measuring antibodies. it is very important. we also know that immunity is very complicated. there are memory cells that we dont do a good job of measuring with our standard blood kept tests. that kicks in. think about, oh hey, ive got a cold before. this time around, it wasnt so bad. similar concept. thats whats helpful when we have a vaccine. even better if youve been infected. just being infected and getting a vaccine. it gives you even more protection. >> i love this, o...

Is influenza and rsv, not covid right now. jon: why? covid, so much of the population has had vaccines? >> thats right, population immunity is high every time you get covid, your memory cells remember it and are more ready to produce antibodies. there are four coronavirus is circulating for centuries and caused the common cold. covid is the fifth even though it has a stigma for case fatality rate that was high, the reality is influenza and rsv have a similar risk profile and higher in certain ag...

They are many times faster than flash memory and require significantly less energy: memristive memory cells could revolutionize the energy efficiency of neuromorphic computers. In these computers, ...

The next phase of the pandemic to keep us safe from the virus so in a simplistic way when you recover from the virus or get the vaccine the body has antibody that is protect you and have memory cells to protect you and what we discovered is the apt bodies go down around four or five months and people get reinfection and the b-cells and t-cells provide really good protection against severe disease and hospitalizations in most people. what does that mean? thats why you see people who have had boos...

So this is not covid, its a related virus. this theory goes that, if youve been exposed to one of those cold viruses in the past, could it be protecting you against covid? that is what this research is looked into. so they took 52 unvaccinated people, and this was way back in september 2020, before people had had the vaccines. so 52, half of those people, in households of those 52, managed to contract covid, and half didnt. they looked at the group, the half that didnt. those ones that didnt hav...

Have two studies coming out in the last week that look at parts of the immune system that are much harder to study than simple antibody levels which you may know, you can look at just with a drop of blood. these studies looked at memory t and b cells and these are cells that once they encounter the infection, sort of go into hiding and if the infection comes out again they get super activated and start pumping out all kinds of things. what these studies showed is the memory cells that were induc...

Three-dose for those over 65 and high immune compromised and people with cormorbidities. were going to learn how we can best prolong memory cells because thats what determines best protection against ilinize and i think its likely we could have protection for years depending on how we use the subsequent doses. >> lets talk about children because theres been delay in the research on whether two doses or three doses are needed and the study group has to extend its period. so, what about the parent...
