Several ongoing coronavirus-vaccine trials could announce game-changing results next month. But as anticipation grows, concerns are growing about whether the vaccines will clear safety trials, what they will achieve if they do and the risk that the approval process will be influenced by politics, or at least seem to be.

FDA expects the vaccines to be at least 50% effective however they prefer it to be around 60% to 75% effective. These are the first wave of vaccines available to the patience infected with the virus. There are likely some new and better vaccines that are in the phase 1 and phase 2 of the clinical trials and they won't be available until some time in spring, summer or as late as fall of next year. Plus, there are possibly new vaccines entering the clinical trials. The experts mentioned that it will take at least 4 years to eradicate the virus and by then there would have been several new and better vaccines available.

They won't expedite the process in the clinical trials. It's imperative that we get a better understanding of these potential vaccines before they are administered to the infected patience. The vaccines that are in phase 3 of the clinical trials have shown some side effects and the experts have to observe the ongoing effects and outcomes before allowing any of the vaccines to be given to the general public infected with the virus. Eventually some of the vaccines will be approved and they will be mass produced to serve a large population.
