Now entering late-stage clinical trials, the vaccine could be approved as soon as 2025.
The new three-dose vaccine is now entering phase 3 clinical trials, for which the company will enroll 6,000 participants from around the world, including children age 5 and up. After the initial doses, people may need an annual shot, as well, Torres said."So it's a bit more complicated than most vaccines, but certainly will protect against something that can be fairly dangerous."
Experts are still investigating the biological reasons why long COVID happens and why a vaccine dose might help. One theory is that long COVID is a type of autoimmune response, in which the body's immune system begins attacking its own healthy cells, Torres said. In that case, theoretically,"the vaccine helps the immune system fine-tune itself and target the germ it's going after," he said.
