Immune cells against COVID-19 stay high in number six months after vaccination, study shows

A recent study provides evidence that CD4+ T lymphocytes -- immune system cells also known as helper T cells -- produced by people who received either of the two available messenger RNA (mRNA) vaccines for COVID-19 persist six months after vaccination at only slightly reduced levels from two weeks after vaccination and are at significantly higher levels than for those who are unvaccinated.
