The various Wuhan pneumonia (novel coronavirus disease, COVID-19) vaccines currently in use around the world have some protection against diagnosis in vaccine recipients, but the occasional adverse reactions that have been reported have caused a lot of concern, with U.S. medical experts revealing that women and people under the age of 40 are more likely to have side effects from the vaccine.
According to Forsyth News, William Schaffner, an infectious disease scholar at Vanderbilt University, pointed out that women and young people have more local reactions to the vaccine, such as sore arms, nausea, discomfort throughout the day, flu-like symptoms, and so on.
Schaffner said there must be a reason for this phenomenon, but the medical community has not yet clarified the reasons behind it, which may be related to estrogen in the case of women. Other experts stress that the vaccine is just as effective in fighting martial lung, regardless of the severity of the side effects.
William Moss, a vaccine scientist at Johns Hopkins University, said some people worry that if they don’t experience any discomfort after vaccination, it means the vaccine is ineffective, but there is no such thing because adverse reactions have no effect on the effectiveness of protection.
