Question 1

How effective is flu vaccine?

Accepted Answer

Every year, WHO studies the strains of influenza virus circulating globally and advise to produce the flu vaccine with those particular strains. Vaccine effectiveness may vary in relation to many factors globally but on a average, flu vaccination reduces the risk of influenza by 40 - 60 % among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine.

Question 3

I've been dealing with a cold, cough, and fever about 10 to 15 days ago. Now, even though my body still feels hot, there's no fever when I use a thermometer. I'm also experiencing a bit of weakness. Any idea what these symptoms could mean? What medication could help prevent or cure this?

Accepted Answer

These symptoms could be related to a post-viral syndrome, where your body is still recovering from the previous cold, cough, and fever. The feeling of body heat without an actual fever could be due to residual inflammation or immune response. The slight weakness may also be a lingering effect of the previous illness. To help alleviate these symptoms, you can consider taking a medication like Paracetamol (brand name: Tylenol) for any discomfort or perceived feverishness. Additionally, you may benefit from over-the-counter cough syrups like Dextromethorphan (brand name: Robitussin) for any lingering cough. Make sure to get plenty of rest, stay hydrated, and eat nutritious foods to support your body's recovery.

Why am I always tired and have no energy?

In most cases, there's a reason for the fatigue. It might be allergic rhinitis, anemia, depression, fibromyalgia, chronic kidney disease, liver disease, lung disease (COPD), or some other health condition.
