Answer:
The answer is letter A, 10 minutes.
Explanation:
Vasovagal syncope is also known as "neurocardiogenic syncope." This happens when a person faints due to some triggers following vaccination. The trigger could be the sight of blood or the body's blood pressure suddenly drops. Although this is not a serious condition, it should be monitored or treated.
The majority of cases of vasovagal syncope occur immediately within minutes of receiving the vaccine. It could happen during or after the vaccination. Thus, the answer is letter a, 10 minutes (since this is the shortest time frame).
Vasovagal episodes should be distinguished from anaphylaxis episodes. Anaphylaxis usually occur within 15 minutes to an hour of receiving the vaccine.
Vasovagal syncope causes some of the following symptoms: nausea, vomiting, cool clammy skin, hypotension, bradychardia, loss of consciousness, etc.
