Yeah the pandemic gave Bitcoin a strong popularity boast.
Sometimes ago I also thought about this question, if Bitcoin would be able to maintain this suddenly increase in the participants now that things are seemingly coming back to normal in terms of the economical rejunevation going on. But I also thought and would like to agree with some of the comments here, saying it would rather futher strengthen Bitcoin's progress, because in many nations like mine, people are back into full business, companies are now running and the general economy is being built again thereby removing the excuse of low or no funds to invest in Bitcoin.
I think the vaccination is equally a good opportunity for Bitcoin to gain strength.
