Since rolling out the booster dose of the Covid-19 vaccine, thousands of people reported the most common side effects



Thousands of people reported numerous different side effects when they received the first and second dose of the Covid-19 vaccine since they were initially rolled out in December 2020.

The side effects vary from one vaccine to another, but the most common side effects were fever, fatigue and pain at the injection site and overall, most side effects were mild to moderate.

Recently, the CDC released the most recent report that stated the most common side effects by the third, booster dose of the vaccine and they claim that the side effects are similar to those that people mostly reported after receiving the second dose of the vaccine.

The results are based on data provided by thousands of people who received the third dose of the Pfizer vaccine, initially approved for people with compromised immune systems.

Among more than 12,500 people who completed surveys after each shot, 79.4% of people reported local reactions (including itching, pain, or redness at the injection site), while 74.1% reported systemic reactions (mostly fatigue, muscle aches, and headaches), typically the day after the shot.  That compared to 77.6% and 76.5% of the people who reported local or systemic reactions, respectively, after their second shot.

What is important to mention is the fact that the result of the survey shows no unexpected patterns of adverse reactions after the third dose of the vaccine, something that many people feared of.

Another important thing to point out is that the third dose of the vaccines didn’t cause more serious reactions compared to the second dose. This is very important for the health officials and experts that would lead authorizing boosted doses of the vaccines for wider population and additional categories of people.

“These initial findings indicate no unexpected patterns of adverse reactions after an additional dose of Covid-19 vaccines; most of these adverse reactions were mild or moderate,” the authors wrote in the new report.

“This latest report includes some of the data of our early experience with third doses,” CDC Director Dr. Rochelle Walensky said during a White House Covid task force briefing.

“The frequency and types of side effects were similar to those seen after the second vaccine doses, and were mostly mild or moderate and short-lived,” she added.
