Why do some people have side effects after COVID-19 vaccination?
Temporary side effects such as headache, malaise, and fever are signs that the immune system is recovering. This is a normal response to the vaccine. And they are common.
“The day after I got these vaccines, I didn’t plan to do any vigorous exercise,” said Dr. Peter Marks, Vaccine Director at the US Food and Drug Administration.
Here’s what’s happening: The immune system has two main arms, the first arm that activates as soon as the body detects a foreign intruder. White blood cells flock to the area, causing inflammation that causes chills, pain, malaise, and other side effects.
This rapid response step of the immune system tends to decline with age. This is one of the reasons why young people report side effects more often than older adults. Also, some vaccines simply elicit more reactions than others.
However, reactions vary from person to person. If you feel nothing for a day or two after either dose, it does not mean that the vaccine is not working.
Behind the scenes, Shot also moves a second part of the immune system, providing true protection from the virus by producing antibodies.
Another annoying side effect: Activation of the immune system can also cause temporary swelling of lymph nodes, such as under the arms. Women are encouraged to schedule regular mammograms prior to COVID-19 vaccination to avoid mistaken swollen nodules for cancer.
Not all side effects are routine. However, after hundreds of millions of vaccinations worldwide and thorough safety monitoring, few serious risks have been identified. A small percentage of people vaccinated with AstraZeneca and Johnson & Johnson reported abnormal types of blood clots. Some countries have booked these shots for seniors, but regulators say the benefits of providing them still outweigh the risks.
People also sometimes have serious allergic reactions. Therefore, you will be required to stay for about 15 minutes after receiving all types of COVID-19 vaccine. This allows you to quickly treat any reaction.
Finally, authorities say that temporary heart inflammation that can occur in many types of infections can be a rare side effect after the types of mRNA vaccines made by Pfizer and Moderna. I’m trying to determine. U.S. health officials say they are monitoring a small number of reports, primarily teenage men or young adults, although it is not yet known if there is a link.
