Covid19 is not something one will pray for,or because the vaccine has been discovered,one should be careless and not ensuring he or she maintains that safety meaaures that will make him or her not to contract the sickness.
These safety measure which is regular washing of hands, avoiding social distancing and using of nose mask is what I have always done which has made me to be covid19 free.
I had never been infected since the start of the pandemic, generally, I was always careful when it came to washing hands/using antiseptic wash, wearing mask correctly and so on. It all needed the inability to avoid some stupid friend's birthday to get infected. Since the PCR showed the Delta variant, I believe that our symptoms would be way worse if we weren't vaccinated.
You have done the exact thing by avoiding Birthday party, only awareness can prevent this pandemic.
For me, till now not infected. There are almost 6 months has been Lockdown in our city. We all complied with the lockdown, I did not go out except necessarily, As well as adhering to clean cleanliness.
And I took the full doses of the vaccine in time, Needless to say, the mask is more beneficial than the vaccine. Since the coronavirus is contagious and spreads through whooping cough, the mask has kept me safe from getting corona.
The best thing is to avoid people who are careless altogether, that specific friend has been infected twice, and was the second time she was putting as in danger. She hasn't been and doesn't plan in being vaccinated, I had plenty of reasons to dislike her, but this was the final straw.
I'd prefer to avoid hanging out in enclosed areas such as bars, clubs etc. we'll have plenty of chances to do it safer, in the summer, enjoying a cocktail at some sunny beach bar, in an outdoor setting. It might not be deadly for most, but I'd rather be on the safe side.
