Abu Dhabi Public Health Centre conducted a study on the efficacy of vaccination in the emirate and found a significant decrease in the rate of Covid-19 infection after receiving a second vaccine dose. The study also showed that in the event of an infection after vaccination, patients have mild symptoms and do not require admission to hospital or an Intensive Care Unit (ICU).
The study found the efficacy of vaccination in preventing hospitalisation is 93 per cent, while the efficacy of vaccination in reducing the need for ICU is 95 per cent. The study also revealed that no deaths related to Covid-19 have been recorded in the emirate by those who have received all vaccine doses required.
The study stated that immunity against Covid-19 is best achieved through vaccination and adhering to precautionary measures, and that immunity is multifaceted and not limited to the presence of antibodies. The study also said that immunity is not guaranteed after infection, as an individual may be infected again.
The study found that the risk of contracting Covid-19 increases as the virus mutates, and that the chances of the virus mutating increase with its spread. It is also possible that after contracting Covid-19, even if the symptoms are mild, the infection may lead to long-term health complications.
The study also explained that the ‘post-Covid-19 syndrome’ may affect some senior citizens, people with chronic diseases, and even healthy individuals. Complications include damage to multiple organs, blood clots, and other complications that may require long-term medical attention.
