There are many side effects to the COVID vaccine booster. Below are seven examples of side effects from COVID vaccine boosters.

My COVID booster shot was my first step. I was anticipating that it would not be as difficult the day after. Before I went to bed, I made sure I cleared my mind and had taken care of all the things on my list. However, other than the mild soreness near the injection site, there was no other symptoms. I finally felt strong enough to take a run.

Talking to family and friends about their booster shots I found that everyone had different experiences. Many people felt slightly unwell and took a break. Some were unaffected like me while some were completely exhausted for at least a few days.

More 26 million AmericansSo far, I have received a boost shot. It is the reactions people have reported after their boostersThey appear to reflect what people feel after. their second dose. The very vast majority of side effects — like chills, aches and pain — are no big deal. If anything, they’re a sign your immune system is revved upProtecting you against COVID-19 by doing everything it should.

Everyone’s going to respond a bit differently, likely due to their age, health and how their immune system responds to vaccines. Below are the experiences of several individuals who have had to deal with side effects from getting their shots.

‘It gave me comfort that my immune system was working …’

Scott Jelinek (a Philadelphia pediatrician aged 33), has been treating patients infected by the SARS virus-CoV-2 virus. Jelinek wanted maximum protection to reduce his chance of contracting the virus or spreading it to others. Jelinek received his first Pfizer dosage in December 2020. He was also keeping an eye out for studies that showed that antibodies levels decrease with age.

Jelinek got his Pfizer booster dosage at the beginning of September. Although he experienced no side effects, Jelinek was still able to function normally the following day. However, his arm became sore and he felt fatigued. These symptoms lasted for a mere day.

He actually felt mild effects and was happy that he had received the jab.

“It gave me comfort that my immune system was working to create the antibodies necessary and it gave me a sense of reassurance that the booster was working,” Jelinek said.

‘A little warm and drained, as if a cold was coming on.’

Rebecca Hui, a 32-year-old mental health clinician, got her initial Moderna doses in In January and February she received a Moderna booster and in November, she was able to receive another. Because of the nature and importance of her job she qualified for a booster. However, COVID was not something that she wanted to pass on to any older family members.

She hadn’t experienced many side effects after her first two doses — just a sore arm and some slight fatigue after dose two — but developed stronger symptoms after the booster. The side effects started about nine hours following the booster shot, and lasted for approximately 12 hours. It felt like she was getting a cold. She described feeling warm and drained. However, by morning the symptoms were gone.

‘I was planning to take a sick day … but I forgot and it didn’t impact my day.’

Luis Gallego, a 41-year-old early childhood education specialist, didn’t experience any noticeable side effects, with the exception of a sore arm, after any of his shots. After receiving his Pfizer first doses, Gallego was able to get a booster of the drug at a local pharmacy. It was late October. “I was planning to take a sick day just in case I would get anything, but I forgot and it didn’t impact my day,” Gallego said.

He chose to get a booster because he was eligible and didn’t want to test his luck — he has been fortunate enough to avoid COVID so far and didn’t want to risk it during his upcoming travels abroad. “I love traveling and I know that increases the chances of getting expose to variants — so the more protected I can be, the better,” Gallego said.

‘The lack of energy put me out. I was still glad I did it.’

Tina, a 69-year-old woman living in Florida, said there was no doubt in her mind she’d get a booster shot when she became eligible. After getting her Moderna shots, she felt well-protected for this holiday year. The booster made her feel a bit drained and she was ready to be ill after taking the first dose.

After getting the booster, around nine o’clock in the evening she developed a headache. She felt very tired and unwell for the next two days and spent much of her time in bed.

“The lack of energy put me out,” she said, noting that her energy levels were restored after about two and a half days. “I was still glad I did it. Knowing what the symptoms were from — it didn’t faze me in the least. I didn’t feel good, but I had no regrets.”

“In comparison to what the body aches feel like when you’re actually sick, it’s so minor.”

‘I had zero side effects aside from some mild shoulder pain.’

Katie Hemcher, a 33-year-old woman who recently had a baby, received the one-dose Johnson & Johnson shot in March. After her J&J shot, she had pretty significant side effects that lasted about 12 hours — fatigue, body pain, chills, a fever — but a big caveat is that she was in the first trimester of pregnancy and was already feeling pretty depleted to begin with.

When Hemcher learned that all adults who received the J&J shot were eligible for a boosterWith the intention of passing on more antibodies to her child, she made an appointment for a Pfizer injection.

“I had zero side effects aside from some mild shoulder pain where I received the vaccine,” Hemcher said of her booster shot.

‘Within 24 hours, I was back to normal.’

Erin, an Illinois-based 40-year old health worker, was very sick last year with COVID-19. Following her treatment, Erin developed debilitating long term symptoms, including severe fatigue, headaches, brain fog, and extreme fatigue. Erin (who preferred to keep her name private) was full vaccinated in January 2021. She began working at a post-COVID clinic for long-term COVID management. Many of her symptoms improved by the summer.

Erin was hesitant to get a booster at first, given all of the long-haul symptoms she dealt with, but her doctor recommended that she get it — plus, she didn’t want to battle COVID again without the most protection. Her booster was scheduled for November.

“I did get fatigued hours later and woke up with a headache, but eventually, within 24 hours, I was back to normal,” she said.

‘A sore armpit is so worth it.’

Katie, a Pennsylvania-based woman of 29 years, asked for anonymity as she said she’s been cautious all through the pandemic. Katie also requested a booster shot in order to be more protected. Her first Moderna dosage caused her to experience injection site discomfort. She had mild body aches, severe headaches and even a low grade fever after the second.

Within 24 hours of her Moderna booster, which was last week, she experienced slight body aches, and some swelling below her armpit. The armpit pain grew stronger the following day, but it quickly subsided on the third.

“In comparison to what the body aches feel like when you’re actually sick, it’s so minor,” Katie said. “A sore armpit is so worth it.”
