They talked heavily about vaccine since people need confidence and some sort of guarantee to restart economy. Closing downs, especially schools and daycares, are causing heavy (and also extra) burden on working classes.
Frankly speaking, current goal set by FDA in covid vaccine effectiveness, as I last check, is somewhere between 50-75% depeding on how optimzed they are, and it is going to be a challenging goal. The number isn't that great to begin with. Even if they came up something great, the next question would be: what's the effective cure for those who are infected (since we have a huge patient base now, it's unlikely for covid to disappear magically after one widespread vaccination, as 1% means hundreds of thousands now)? There is also possibility of people stopping self-protection after they got the shot, which is likely to raise infection counts afterwards, especially when effectiveness of the vaccine isn't 100%.
That question, in effective cure/medicine, is rarely spoke of since there is probaly not going to be one. There is simply no hope in it. We still don't have an effective cure for SARS that occured in 2003, and MERS in 2015. There are only a handful of successes against viruses in human histroy and most took a very long time to achieve. COVID is unlikely to stray away from that pattern.
