Possibly. We are at the final stage of the vaccine development and it is just a matter of time which company would confirm on the dates. Once confirmed, we are talking about the logistical aspect of distributing it worldwide.
When that happens, would the gloves manufacturers still be in demand as before ? I believe sales may taper down slowly as many countries are still not out of the woods and safety precautions will still be needed somehow.
Distribution of vaccines is going to take time, leaving pockets of opportunities as well. The need for hygiene in sectors like Catering, F&B, airlines, etc would increase and gloves in these sectors may increase to compensate for the declining ones.
Chart wise, can wait for the breakout to take place first. It can go either way, so be patient.
