How effective is flu vaccine?
Answered by 1 Apollo Doctors
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.

View allI'm really confused about my situationI've been feeling weak for the past two weeks. When I went to the doctor, they said it's likely a viral infection. But I'm also dealing with congestion in my head and ears, like there's something similar to a cough. After five days of taking meds, nothing's changed. The doc suggested a blood and urine test; everything came out normal except my S Typhi O levels, which are 1160 positive. Does this mean I have typhoid? I'm not running a fever, though, my temperature is just around 97. Could this still be typhoid even without a fever?
Based on your symptoms and the positive result for S Typhi O, it is possible that you have a mild form of typhoid fever. Even though you do not have a high fever, a positive S Typhi O test result at 1:160 indicates exposure to the bacteria that cause typhoid. It is important to complete the full course of antibiotics as prescribed by your doctor to ensure the infection is completely cleared. Additionally, make sure to stay hydrated and get plenty of rest to help your body recover.

I'm really worried because someone I know tested positive for Covid and had symptoms. But after about 5 days, the symptoms went away. Do we really need to do another Covid test now, or is it okay to skip it since theyre feeling better? I'm just unsure if there's a risk, so some guidance would be really helpful.

I've been having a really annoying dry cough lately and it's been keeping me up at night. I've tried drinking more fluids and using a humidifier, but it's not getting any better. Do you have any recommendations for a good cough syrup specifically for dry coughs? I'd love to know what might actually help soothe this!
You can use Grylinctus dx or Ascoril
