Immunity against COVID-19 has become one of the main challenges for mankind. However, its achievement is costing a lot due to the mutations that are occurring in the virus. At present, immunity can be achieved in two ways: vaccines and having recovered from the disease. The specialist in Public Health and Preventive Medicine, Joan Carles MarchSo far 868,461 people, or nearly 15% o, stated that “it is not yet clear what happens with natural immunity. In previous studies it was said that vaccination plus natural immunity protected more than vaccination alone. At the moment there are those who suggest that there are new infections in patients who have natural immunity. This makes it necessary to study it calmly”The pandemic fatigue right now is so strong,.
March adds that “in studies in June of this year it was said that those infected are capable of generating antibodies against the coronavirus for the rest of their lives; one study shows the presence of long-lasting immune cells even in people who have had a mild or moderate infection. However, another story is now being told. Nearly two years into the pandemic, questions about immune responses following COVID-19 remain unclear.”
The Public Health specialist clarifies that “immune responses are either innate or acquired. Innate, or short-term immunitys inauguration in 1961, occurs when the immune cells that constitute the body’s first line of defense are activated against a pathogen, such as a virus or bacteria. What is now known is that natural immunity is not sufficient, and contracting COVID-19 and recovering does not seem to generate protection as strong as that generated after vaccination.”
