Experts explain ... why do we feel the symptoms of the second dose of the Corona vaccine more often?

Experts in the health sector explained the reason why the symptoms of the second dose of the Corona vaccine were stronger compared to what they felt upon receiving the first dose, as evidence that the second dose effectively performs its function as a result of the immune system’s response, and thus provides long-term protection against the virus. .

Symptoms range from arm pain, headache and nausea, according to "Sky News".

There is no difference between the first and the second dose, they are both completely identical.

However, the first dose simply preps the immune system so that it is ready to trigger a more powerful response when the time for the second dose comes.

"The second dose is just an amplification, enlargement, or expansion of the first dose," said infectious disease expert at Johns Hopkins School of Public Health, Diane Griffin.

Common side effects from the vaccine include pain, redness, and swelling in the arm that receives the injection, according to the Centers for Disease Control and Prevention in the United States.
