Vaccination against COVID-19 carries the risk of side effects. Each manufacturer lists in detail what reactions may appear after taking its preparation. Clinical studies, as well as post-vaccination reports, show that the effects of vaccination can vary with age, gender, dose, and whether or not the vaccinated person has had a COVID-19 infection. Who is at risk from vaccines more severely?
- Almost 600 million doses of the COVID-19 vaccine have already been administered worldwide
- In Poland, until April 1, almost 6,3 million doses were administered. Vaccine effects occurred in about 5,5 thousand. people. In Poland, the vast majority of side effects of vaccinations occurred in women
- In addition to gender, there are several other factors that influence your risk of side effects. What kind?

Side effects from COVID-19 vaccines
Vaccination against COVID-19 is ongoing worldwide. Several preparations are in use, the most popular of which are Pfizer / BioNtech, Moderna, AstraZeneca and Johnson & Johnson. The mild side effects listed in the package inserts for these vaccines are very similar. The most common are pain, tenderness and redness at the injection site, headache, muscle aches, fatigue, chills, nausea and fever.
However, the effects of vaccination may vary with age, gender, and health status. The effects may also be different depending on whether we have the first or second dose of the vaccine. This is due to clinical trials as well as data collected among vaccinated Americans. Business Insider writes about them.
Side effects of the COVID-19 vaccine. They are more serious after the 2nd dose
The most common side effect for all three US-approved vaccines is pain or swelling at the injection site. This effect appeared in almost 92 percent. participants of clinical trials conducted by Moderna. In the case of the Pfizer vaccine, it was 84%, while in those vaccinated with Johnson & Johnson’s vaccine, the figure was 49.
AstraZeneca is not used in the US, but it is authorized in EU countries. The mentioned side effects appeared in 64 percent. clinical trial participants.

Other common side effects include fatigue, headache, and body or muscle aches. About 65 percent. people vaccinated in the Pfizer and Moderna studies, and 38 percent. fatigue has occurred at Johnson & Johnson.
About twice as many participants in the Pfizer study had chills and joint pain after the second dose than after the first dose.
In turn, clinical trials of Moderna show that about five times as many participants experienced chills after the second dose than after the first. The same applies to fever – it was reported much more often after taking the second dose than after taking the first one.
Side effects of the COVID-19 vaccine. More serious in people who have COVID-19 behind them
A study by the Icahn School of Medicine in Mount Sinai found that side effects of vaccines such as fatigue, headaches, and chills were more common among people with pre-existing immunity to coronavirus than in people who had never been infected.
About 73 percent. Vaccinated people who had previously had COVID-19 reported side effects after the first dose of a Pfizer-BioNTech or Moderna injection. By comparison, the percentage was 66 in those vaccinated who were not previously infected with the coronavirus.

“If you already had COVID-19 infection, you activated the memory cells of the infection after vaccination,” explains Dr. Vivek Cherian, an internist from Baltimore. – If you were ever exposed to the infection again, your body may react faster and stronger the second time around. Hence the trend towards stronger side effects of the vaccine in those who have had COVID-19 infection behind them, he added.
Side effects of the COVID-19 vaccine. Less common in the elderly
Our immune system gradually deteriorates with age, which means that older people’s bodies work less well when it comes to defending themselves against pathogens as well as proteins introduced into the body through a vaccine.
“Younger people have a much more vigorous immune response, so it follows that they also report more side effects,” Cherian explains.
What does the data look like? After the first dose of the Moderna vaccine, adverse effects occurred in 57 percent. people under the age of 65. Among people over 65, such effects appeared in 48 percent. However, after the second dose, adverse effects occurred in 82% of patients. people under the age of 65 and in 72 percent. in people over this age limit.

In turn, the Pfizer reports show that 47 percent. people aged 18 to 55 and 34 percent. people aged 56 and over felt tired after the first dose of the vaccine. With the second dose, 59 percent of it occurred. from the first group and 51 percent. the other.
When it comes to the Johnson & Johnson vaccine, side effects occurred in almost 62% of people. people aged 18 to 59 and in 45 percent. vaccinated in the 60 plus group.
Side effects of the COVID-19 vaccine. They are more common in women
The US Centers for Disease Control and Prevention (CDC) examined Americans’ responses to nearly 14 million doses of Pfizer and Moderna vaccines given between December and January. Women accounted for 61 percent. vaccinated, and the results showed that they reported about 79 percent. cases of side effects
This is in line with previous data that women tend to be more responsive to polio, influenza, measles and mumps vaccines.
All of these vaccines are more likely to cause side effects in women. They’re even more prominent in premenopausal women compared to postmenopausal women, Cherian commented.
- How do I deal with the side effects of vaccination? [WE EXPLAIN]
Scientists suspect that the difference has to do with estrogen levels. – Testosterone is rather an immunosuppressive hormone and estrogen is an immune stimulator. So it is more than likely that the increased side effects are due to female hormones, he added.
How does it look in Poland? According to the data of the Ministry of Health, by March 31, adverse vaccination reactions occurred in 4463 women and 773 men. It follows that NOPs in women constitute as much as 85 percent. whole.
Side effects of the COVID-19 vaccine. Chronic diseases have no effect
People with weakened immune systems are more susceptible to viral infections and are more likely to experience severe COVID-19. It is also very likely that such people have a weaker immune response to the vaccine.
– The immune response affects side effects, so if you are immunocompromised, you may be less likely to experience these effects. Nevertheless, you absolutely should get vaccinated, Cherian said. “The effect of vaccinations in the form of diarrhea or muscle pain is always better than the severe, life-threatening complications of COVID-19 infection,” he added.

The same applies to autoimmune diseases. People with these conditions may be less likely to experience side effects after being vaccinated against COVID-19.
