Talking about the immune system and Vitamin D makes sense but you have to include zinc and quercetin, which assists in metabolism of zinc.
Delta Covid is currently being crowded out by Omicron, which is not a Covid variant at all. It is a new coronavirus common cold. Omicron has 30 mutations of the spike protein. A new Covid variant would have one or two. Omicron has exactly the same symptoms as a common cold. A new Covid variant would be much more deadly.
While catching a cold is no fun, catching an Omicron cold is nothing to worry about. You will be healthy again in few days. The probability of needing hospitalization or dying is very low, just like with any common cold. People with a weak immune system can develop more serious complications.
It may not seem that Omicron is low risk, however, because Omicron spreads so rapidly. Many people get infected quickly. Although the probability of needing hospitalization is very low -- the SAME as a common cold -- a huge number of Omicron infections at one time will send more people to the hospital at one time. The current PCR tests do not distinguish between various coronoaviruses. If the symptoms are serious, the probability that the infection is Omicron is very low.
There are early indications natural antibodies after recent recoveries from Omicron, and other coronavirus common colds, offer some protection from Delta Covid. Not a lot, but some. Obviously a healthy immune system is most important, but for the elderly, with multiple comorbidities, that will be impossible goal.
The important news now is that Omicron is crowding out Delta Covid. If the trend continues, the pandemic will end. I believe it will end before this Summer 2022. There may be a lot of Omicron infections this winter, but there is no such thing as a common cold pandemic.
What does one do to prevent Omicron? Covid vaccines and boosters are nearly worthless, as the current explosion of omicron infections makes very obvious. Cheap masks are nearly worthless. N95 masks are not much better. Six foot social distancing is not going to work if you are in the same room as an infected person for a while, with no windows open.
The only prevention is a healthy immune system. Even then you might have "the sniffles" or not feel "100%" for one day while your imbue system defeats Omicron. A healthy immune system not something you can develop in a few days. But so what? With an Omicron infection, you will feel better in a few days, just like having a common cold. Because you did have a common cold. Omicron is completely different than Delta Covid. Government scaremongers who want to keep you in fear, under their thumbs, don't want you to know that.
Concerning the alleged success of the vaccines:- I have compared US deaths with Covid, and total US deaths, in 2021 versus 2020, using the latest available CDC data (preliminary data for 2021). in 2021, both US deaths with Covid, and total US deaths, were HIGHER than in 2020. That is evidence the vaccines were failures. More deaths with the vaccines in 2021 is not success.
Concerning the 22,000 Covid vaccine side effect deaths reported to VAERS. Looking at other years, from 1990 through 2019, for ALL vaccines in that year, a typical year has about 400 deaths reported, versus 22,000. 22,000 is a very serious problem, knowing only 1% to 10% of vaccine side effects are ever reported.
Anyone who says mRNA vaccines are "safe" is either not very intelligent or not aware of the unprecedented reported adverse side effects -- the worst, by far, in the history of vaccines. And we still do no know the adverse long term side effects. Of course I am not vaccinated -- I do not let government bureaucrats falsely claiming to be Covid "experts" run my life. I have informed myself and i do not consent to Covid vaccine, which are not safe and not effective. Completely worthless with Omicron.
