It is strange, but many vaccinnated people around me think that as soon as they get the first dose of the vaccine, they can relax, ease anti-COVID limitations, stop keeping social distance, wearing masks, etc. It is quite understandable that people are very tired of all those limitations, but the rules are well-known. For example, after Sputnik V vaccination sufficient amount of antibodies work out only after three weeks after the second vaccination. There are also three weeks between first and second vaccination. So, altogether it is a six weeks period.
When you know how much time left to wait, it gets easier to conduct countdown, especially since you had already waited for much more. So, you have to have patience.
I cannot stress it enough: please do not relax immediately after the vaccination! You are completely not protected. So, if you considerably ease the limitations, you put yourself at substantially more severe risk to get sick with COVID. So the vaccination becomes not your protection but a significant risk factor for your health.
Take care of yourself and stay safe.
