A COVID-19 vaccine would solve our problems and prevent infections, but a lot of answers are still unknown to us.
A vaccine would teach our body to develop antibodies and recognize the virulent strain but doesn’t eliminate the virus altogether. How much immunity it would really deliver, or cut down transmission risk are still some lingering questions.
Secondly, the effectiveness of COVID vaccines is still to be considered. Even though there are numerous vaccines under offing, we still don’t know which are how many vaccine shots will be effective and garner the most protection. The range of vaccine efficacy also varies from clinical testing and real-world settings. Hence, a vaccine may not show the same exact results as it did in the clinical settings.
Therefore, it would be wrong to fully pin our hopes on a vaccine and conclude the pandemic has drawn to an end, at least right now.
