In a recent study published in The Journal of Immunology, a team of researchers from Japan examined the memory B and T cell responses to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein after the booster dose of the coronavirus disease 2019 (COVID-19) messenger ribonucleic acid (mRNA) vaccine BNT162b2. ....
The third dose of an mrna and second dose of the j&j. it s natural for the antibodies to go down, but there are things that aren t easily measurable, to look at the level of the memory response, both memory b-cells that make antibody and t-cells that give you durable protection. if that goes out for a longer period of time, that will determine how often you need to get boosted. i don t think one can project that right now until we get the data. are there any signs of the booster shot or that third dose having diminishing protection? we know some people got that third dose, more than five months ago. should they be worried? well, i shouldn t say they should be worried. i would say what they need to do ....
Protections won t exist? no. i think we are still looking at those data. the immune system is a remarkable thing. people s bodies will continue to make antibodies and t cells and memory b cells will be there. so when people get infected with the covid virus, they will be able to respond to it. but in order to be kept out of hospital, to be protected against death, know that you need to have high levels of antibody as the first line of defense. so that s what s so important about the data. . margins matter here a little bit, though. i don t know specifically what the percentages are. one of the things we have seen in some cases, you know, you are 98% protected against hospitalization if you re fully boosted versus 92% protected if you re not fully boosted against hospitalization. is that what you re talking here? you still have a great deal of protection, but it s not perfect? ....
Report is that they have studied people who got vaccinated with the chinese vaccine which is known to be poorly effective. we ve got to remember that you ve got two levels of immunity when you are immune. antibodies and the memory b cells and t cells bear the memory b cells and t cells encompass all variants and they have encompassed every variant in preventing severe illness and death and that is 100% bulletproof because sean: dr., i don t want to interrupt you but i want to highlight what you are saying here and that is even after antibody levels, if you had covid-19, you still have t cell antibodies and as you rightly point out, that probably is the best immunity one could have because your body would instantly recognize any variant of any coronavirus. is that correct? then immediately the body would begin its immune defenses? that is exactly right. when you have immunity you ve got this army of memory b cells and t cells that will protect ....
