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 a bit concerned about my wife's recent blood test results. Her eosinophil count is 16% and her ESR level is 29. She had a herpes infection two months ago and a food infection about a month before the test. She also took a muscle relaxant nine hours before her fasting blood test. Do these results indicate anything serious? Should we consider getting another blood test after some time?
The elevated eosinophils count and ESR level could be due to the recent infections your wife had. It is known that infections, including herpes and food infections, can cause an increase in eosinophils and ESR levels. Additionally, the muscle relaxant taken before the fasting blood test may have also influenced the results. It is advisable to wait for some time and then repeat the blood test to see if the eosinophils count and ESR level have returned to normal levels. If there are no other concerning symptoms, it is likely that the values will normalize once the infections have resolved and the effects of the muscle relaxant have worn off.

I'm looking at my Widal test report, and I'm not quite sure how to understand it. It says S. Typhi O and S. Typhi H are 1:80 positive, while S. Para Typhi A and B are both negative. Does this mean my typhoid levels are high, medium, or low? Also, should I be changing anything in terms of my medication or diet and water habits?
Widal Test Report indicates a positive result for S. Typhi O and S. Typhi H, with titers of 1:80 each, suggesting a possible typhoid infection. The S.Para Typhi "AH" and S.Para Typhi "BH" results are negative, ruling out Paratyphoid infection. Since the Malaria Parasite test is negative, it confirms the absence of malaria infection. Based on the Widal Test results, the typhoid infection can be considered as moderate. Common medicines for treating typhoid include antibiotics such as Ciprofloxacin or Azithromycin. It is important to complete the full course of antibiotics as prescribed by a healthcare provider. In addition to medication, it is essential to focus on dietary and lifestyle changes. Patients with typhoid fever should consume a bland diet that is easy to digest, including soups, boiled vegetables, and rice. It is crucial to maintain hydration by drinking plenty of fluids such as water, coconut water, and oral rehydration solutions. Avoiding raw or undercooked food, as well as practicing good hand hygiene, can help prevent further spread of the infection. Make sure to follow up with your healthcare provider for further evaluation and management of typhoid fever.
