So Vaccination Drive has been started in Pakistan and it's kinda going good but i'm not sure if it's really going effective at the very moment. So i have decided not to get vaccinated until maybe june or july because the vaccine seems to be not efficient at all.

Sounds good!.. but you failed to mention what vaccines are we talking about here?

(...) but i'm not sure if it's really going effective at the very moment. (...)
I have heard from my relatives who has got vaccinated that the vaccine has weird symptoms like alot of them said having headache and on second dose having bad aches. Alot of them said the same thing, (...)

Those symptoms are commons and EXPECTED as the vaccine has to trigger a mild reaction from your immune defenses.. in other words, it's doing its intended work.. But all those various physiological reactions (fever, fatigue, chills, headache, muscle pain, joint pain etc..) are(/must be) all short-lived.

(..) So a relative got vaccinated like two doses and 1-2 week after he is covid positive so i'm not sure whether i should get vaccinated or not.

It's certainly possible after just 2 weeks from the 2nd injection to test positive!.. Theoretically the total immunization needs 3 months after getting the second dose; that's why people are told to wear a mask!..

Besides, with the Variants poping-up everywhere, people fully immunized against the original version of SARS-CoV-2 can still get infected with one of its elusive variants.

The point of being vaccinated is not to prevent infection BUT to not get too sick to the point of needing hospitalization; that's to say that vaccination will prevent hospitalization and death in case of infection..

(...) So i have decided not to get vaccinated until maybe june or july because the vaccine seems to be not efficient at all.

Need your opinion! Kinda scared af.

Don't be!.. Just get vaccinated as soon as possible... It's silly to postpoint it if you can get it sooner... IMO.
