The question is: why?
The US news site wgno says side effects that occur after receiving the second dose include fatigue, headache, chills, fever, nausea, and muscle pain.
Johns Hopkins University Professor of Medicine William Grino explained that there was a simple explanation for the increased side effects with taking the second dose.
The vast majority of vaccines approved by countries around the world so far consist of two doses, with an average interval of 3 weeks, with the exception of the “Johnson & Johnson” vaccine, which consists of a single dose.
The American expert adds that after the first dose, the body begins to build the first immune response, including antibodies.
And with the second dose, the body’s immune system begins to respond, according to Grino, who says that once the immune system recognizes the vaccine (after the second dose), it will respond more to it.
This is a sign that the vaccine is working and that your immune system “recognizes the vaccine in your body”, according to the American expert.
With the second dose, your body not only makes antibodies, but also stimulates the lymph nodes and other parts of the body to interact with the vaccine at the tissue level, resulting in more serious side effects.
Richard Kennedy, professor of medicine at the Mayo Clinic College of Medicine, believes that the side effects after receiving the vaccine are due to two things.
Kennedy explains that your immunity has two different components: innate immunity and adaptive immunity, and innate immunity is your body’s first response to external invaders.
He said that innate immunity works to slow the attack on your body, after adaptive immunity takes over the fight against viruses, and “B” and “T” cells are formed to counter these bodies. foreigners.
When you receive the vaccine, innate immunity is boosted, and after about a week and a half the stimulating immunity begins to be active and protects the body against the virus.
