Good evening,I am 25 years old male I got vaccinated with sputnik v first dose 20 days ago, On that night of the vaccination day I got chills and high fever and fever lasted until next day evening and I also had fatigue and lot of body pains. I took 3 dolo 650 tablets during fever. It got normal after a day (only pain at injection site was there). I am having a vaccine appointment this Sunday for second dose, I heard that side effects will be more severe after the second dose. Any precautions or suggestions to avoid severe side effects. Thanks in advance
