[Apologies in advance for the rant. We are all impatient!]
No one on the forum knows. No one in Spain knows. No one in the world knows how the pandemic will have progressed by this summer! The only accurate answer is "maybe, maybe not" and many of us think that the "not" is more likely.
On the forum we have been guessing and conjecturing, complaining and hoping for over a year, non-stop. You can see this from all of the Covid threads and Lockdown threads in
this section of the forum, which has almost 10,000 posts! We all rely on the same sources of information - news media and government sources, and they don't know either!
Your vaccination is just one piece of the puzzle - the other millions/billions of pieces are the other people and the variants of the virus.
Only time will tell. We are all hoping that things will open up by the summer, but not many of us are making travel plans yet! Not many of us are even making plans for social gatherings at home.
