COVID 19 Vaccines And Side Effects: Everything You Need To Know


After a year-long lockdown and fear of the pandemic, the covid 19 vaccines have been found. Millions of people around the world have taken the vaccine shots. However, there are a lot of doubts about what to expect after this procedure. This article will talk about the common questions that arise about the covid -19 vaccine.

1) How many shots do I need to take?

Vaccines by Pfizer-BioNTech and the Moderna vaccines require two shots, whereas the Johnson and Johnson vaccines need only one shot. The time break between the first and the second shot is an average of 60 days.

2) Will there be any side effects?

The side effects of the vaccines are only short-lived. They include muscle aches, fever, headache and fatigue. Patients who experienced these often addressed their issues like the bad flu, which made them tired and useless for some days.

Doctors have also suggested that the people who have scheduled their vaccines should plan them in such a way they can take a few days off from work or school. It is after the second dose as they would experience some discomfort.  People are also suggested to track the type of side effects they experience after the vaccination. 

3) What are the common side effects of Pfizer-BioNTech shots?

Studies say about 29 per cent of the people who took Pfizer-BioNTech shot experienced fatigue after their first shot. It increased to 50 per cent after they took the second shot. About 17 percent of the people experienced muscle pain after the first,  which increased to 42 percent after the second shot. The New York times’ interview with several people who were newly vaccinated had new reports.

They ranged from no side effects to extreme reactions like shivering and dullness. The result of side effects is because of the immune system’s reaction to the medicine that is injected into the body. 

4) Does it mean that the immune system isn’t responding if there are no side effects?

Data from many people and also clinical trials show that not everybody experiences the exact prescribed side effects. One out of the four people who had taken the Pfizer shots did not experience any side effects. One in five patients who took the Moderna shots also did not experience any side effects. However, the real question is whether there is any problem if there are no side effects. 

According to Dr Paul Offit, a professor at the University of Pennsylvania, during the vaccine trials, many people did not show any side effects but 95 per cent of them were still protected. So the lack of side effects doesn’t mean the people are not protected.
