A person who has had COVID-19 and chooses to be vaccinated within a specified time frame is likely to experience side effects, as expected. However, those with a history of COVID-19 tend to suffer from severe reactions and experience intense side effects with their jab. This has been seen not only by anecdotal evidence, but also by multiple research and case studies. In fact, those who have had COVID-19 are more likely to experience side effects than those who lack natural immunity.
According to a study conducted with the administration of the Pfizer COVID-19 mRNA vaccine, which is also expected to arrive in India soon, people in the focus group, who had previous experience with the SARS-COV-2 virus had a profile of ‘side effects slightly higher than usual. Similar inferences were also drawn among people who also received the Covishield (Astrazeneca) vaccine.
While side effects of severe intensity could no doubt make the experience unpleasant, one of the main reasons experts believe people with a history of COVID-19 have more side effects is due to ‘a level of natural immunity, including memory B cells present in the body. To give you a better perspective, an encounter with COVID strengthens the natural immunity in the body. Our immunity is made up of strong infection-fighting white blood cells, or antibodies, T cells and memory B cells. While antibodies may decrease over time, the memory B cells mapped into the system “recognize” the characteristics of the infection when the antigen (even if it is harmless) is introduced through the vaccine. Administration thus prompts the immune system to remember the pathogen, triggering more robust and fast-acting antibodies, which then manifest as side effects of “severe” intensity. Therefore, a person with a history of infection is more likely to experience intense reactions, which may be high fever, severe pain, body aches, myalgia, severe weakness, profuse sweating, or even pain. gastrointestinal problems.
