VACCINE CANDIDATES

There have been many attempts to construct a vaccine that is both protective and has a low cost of production; yet, there is still not a promising candidate. Part of the problem is that to be effective the vaccine has to be given early or before exposure to the virus. Ideally a vaccine could prevent the disease entirely or at least shut down the viremia phase. For the sake of convenience, we have listed the vaccine approaches separately with their promises and caveats.
