Amid the gloom of the coronavirus pandemic, the development of vaccines raised hopes of overcoming this disease. The immunisation drive started in 2021 but soon, jab shortages were declared in some states. Simultaneously, India was hit hard by an extremely difficult second wave of Covid-19. 

The situation is improving in parts of the country and a few people are being vaccinated, however, there are still questions that need to be cleared. Dr. Sameep Sehgal, a pulmonologist at Temple University Hospital, Philadelphia, has been treating Covid-19 patients in intensive care since March 2020. Talking about his personal experience, he says the knowledge around treatments and benefits has been changing a lot in the last 12 months. “In my opinion, sometimes ‘less is more’ and adding medications indiscriminately with no proven benefit can do more harm than good. We will continue to learn a lot in the next few months about this disease and we should be ready to adapt our medical practices.”
