This paper shows that people who recovered from SARS 17 years ago also had cross-immunity against COVID. This indicates that T-cell immunity works for a long time and is resistant to mutation.

The T cells of symptomless infected people produce large amounts of two proteins called IFN-γ and IL-2. These proteins help to adjust the immune response. This allows the infection to be cleared without causing a cytokine storm.

The important thing is to take nutrition that is good for the immune system in order for the immune system to work properly. Vitamin D is an essential nutrient for T cells to work properly. It can be made in the skin when exposed to sunlight.

The efficacy of vitamin D against COVID has been obtained from clinical results. Kind hearted doctors are still uploading their data.
@dockaurG The loss of antibodies is actually rational. This is because coronaviruses mutate, and the antibodies are ineffective. In SARS, vaccines were not made, because ADE occurred in animal experiments. The one way to beat viruses is to take vitamin D to activate the immune system.

True. Cross-immunity works if the viruses are similar. In this paper, half of the samples (n=37) that were not infected with SARS showed cross-immunity responses.
Sailors who spend a lot of time on ships are said to be careful to take a lot of vitamin D. This is because they don't want to get sick on the sea. Vitamin D activates immune function. It is said to be an essential nutrition for T cells that destroy infected cells.
If you are young, most people will recover from the infection and cross-immunity will work after that. Vaccines may also be effective for the elderly and those suffering from diseases.
@JamesTodaroMD Excellent work, Dr.Todaro.
I'm Japanese and I've been wondering about the difference in severity and mortality rates from the new coronas between Asia and the Western world. Then I was surprised to see the paper in Nature on July 15.
@JamesTodaroMD Seventeen years later, memory T cells in SARS survivors are still responding to the new coronavirus, and the positive rate of antibody tests in Tokyo in June was only 0.1%. Almost no antibodies were produced.
@JamesTodaroMD This means that even before the pandemic, some kind of virus had already caused memory T cells to react to the new corona virus in Japan.
This is true for all of Asia, including Japan.
