While the leaders of the United States are working to find a cure against the spreading of COVID-19, scientists all over the world are trying to find the mysteries around this virus. One of the most exciting questions is regarding the fact that the symptoms are different from one individual to another, and the scientists cannot seem to find a reason.
Some scientists suggest that the answer to this question is the fact that some individuals might have already got a vaccine for numerous other diseases. Doctor Andrew Badley, an infectious disease specialist, working for the Mayo Clinic, has declared for CNN’s Anderson Cooper that the setting of COVID-19 disease has shown researchers that people who have had prior vaccinations are at low risk of getting infected with the new virus.
The immunologists suggest that this technique is called “immune training,” and it is when an individual’s immune system is trained to fight off infection. Badley compared this theory to a muscle since the more you train that muscle, the stronger it will be. However, up until now, the scientists did not manage to find any evidence to support this theory.
Two months ago, a group of scientists decided to treat a group of patients infected with the deadly virus by administering them measles, rubella and mumps vaccine, in order to determine their influence on the patient’s recovery. Last month, other doctors promoted their discovery according to which the tuberculosis vaccine Bacillus Calmette-Guerin diminished the mortality rate and can boost people’s immunity.
On the other hand, once you are infected with the virus, the severity of your symptoms must also be taken into consideration. According to Dr. Monica Gandhi, approximately 40% of those affected with COVID-29 do not experience any symptoms. This is why it is of the utmost importance to use masks, whether you have any symptoms or not.
