I've not heard anything about how effective the vaccine trials are (although J&J just paused their trial due to an unexplained illness). Really hoping we get something above 90% effective.
J&J did, however, claim they will have enough data to apply for approval by the end of the year. Astrazeneca and Moderna have both said they'll be even earlier than that. And you wouldn't apply for approval if your data didn't meet at least the minimum 50-60% efficacy threshold.
So it looks like things remain on track. However, there's definitely growing anti-vax concern, nationally, that IMO seems to be driven mainly by the Dems and their media. Even if it's 100% effective, it doesn't look like enough people are willing to take it to wipe out the virus.
