Covid vaccine that creates T-cells ‘gives better immune response than current jabs’
A new vaccine designed to specifically create
T-cells against Covid produces a better immune response than the alternatives already in use, according to trial data.
The CoVac-1 jab has been developed and made by academics at the University of Tubingen, in Germany.
The cells form part of the immune response to
protect people against infections and often work in tandem with antibodies. However, while antibody levels often
decline over time and need boosting, T-cells have the ability to stay in the bloodstream for several years.
Evidence is emerging that T-cell levels from vaccines may be key in conferring long-term protection against Covid, but studying the level of them in a person's system is difficult.
