Scarring after a new crown vaccine may be due to mild inflammation occurring.
The types of new crown vaccines are inactivated vaccines, attenuated influenza vaccines, adenovirus vector vaccines, and recombinant protein vaccines.
Among them, both attenuated influenza vaccine and inactivated vaccine require the culture of the pathogenic bacteria, and then strains with little or no virulence are selected and injected into the body in order to produce antibodies. If the concentration of germs in the injected vaccine is very high, mild inflammation may occur, including fever, redness, swelling and pain. Scarring occurs once the swelling goes away.
Usually scars from vaccinations are not large and do not require special treatment. If the patient minds, it is recommended to treat the scar by massaging and applying vitamin E when it first forms, the earlier the better the result.
It is recommended to go to a regular hospital.
