It refutes your claim. If humans can only be immune to a maximum of 12 pathogens, why are many, many, many more of us not sick?
Can you quote a legitimate authority to corroborate this?
I'm only 72. I've never read anything to suggest a human body dozen immunity limit.
I urge you to post / quote the source of your information.
R5 point:
NIH counterpoint:
Outside clinical trials, the first COVID‐19 vaccine was administered on 8 December 2020. Researchers aimed to quantify the global impact of the first year of COVID‐19 vaccination programmes using mathematical modelling to fit COVID‐19 transmission and vaccination to reported COVID‐19 mortality and all‐cause excess mortality in 185 countries and territories.1 They determined the number of lives lost if there had been no vaccines. Based on reported COVID‐19 deaths, vaccinations prevented an estimated 14.4 million deaths (95% credible interval [Crl] 13.7–15.9) from COVID‐19 in a year. However, if excess deaths were used, this estimate rose to 19.8 million (95% Crl 19.1–20.4) deaths prevented (Fig. 1), equating to a global reduction of 63% in total deaths (19.8 million of 31.4 million) https://pmc.ncbi.nlm.nih.gov/articles/PMC9537923/ bold emphasis sear's
I don't get your point because traditionally almost all humans have had at most 4 immunities from vaccinations.
Measles, mumps, chicken pox, and Polio.
Almost no one gets a vaccination for whooping Cough/Pertussis since the vaccine only lasts such a short time.
And until they started the bogus flu vaccines, the only other immunities people had, were only from recovery.
People do not get all these other pathogens because they are very uncommon and are mostly from animal crossovers.
There is not a single valid piece of data even remotely suggesting the mRNA vax prevented a single death.
And in fact, all covid death actually were not caused by covid, but by an over active immune response that caused pnemonia.
The actual cause of death was always pneumonia, not covid.
There was a slight increase in immune system response cause by the mRNA injection, but only for 2 weeks.
And in the long run, that increase in immune system response did more harm than good.
