Adequate Vitamin D is apparently mandatory for naïve T cells to be activated against SARS-CoV-2 and other pathogens

"So why are some people unable to mount a good protective T-cell response? The key to this question might be a 10-year-old Danish study led by Carsten Geisler, head of the Department of International Health, Immunology and Microbiology at the University of Copenhagen [8]. Geisler noted that "When a T cell is exposed to a foreign pathogen, it extends a signalling device or 'antenna' known as a vitamin D receptor, with which it searches for vitamin D,", and if there is an inadequate vitamin D level, "they won't even begin to mobilize." In other words, adequate vitamin D is critically important for the activation of T-cells from their inactive naïve state. The question of whether T-cells might also need a continuing supply of vitamin D to prevent the T-cell exhaustion and apoptosis observed in some serious COVID-19 cases [9] deserves further research."

For some people, the second dose in a COVID-19 vaccination series is causing a stronger reaction and more side effects than the initial dose. That was also true during the clinical trials.

Dr. Poland says a reaction does not mean anything is wrong. "It's an indication that your body is revved up, prepared to do battle against what it thinks is a foreign invader." If people have less of a reaction, it does not mean they aren't developing an immune response, Dr. Poland emphasizes.

Dr. Melanie Swift, co-chair of Mayo Clinic's COVID-19 Vaccine Allocation and Distribution Work Group, says all vaccines could cause some degree of reaction. The same is true with the COVID-19 vaccines.

"They do provoke an immune reaction, which can cause symptoms," says Dr. Swift. "That shouldn't be confused with being harmful or being unsafe. It's what the vaccine is intended to do." Learn more:
