Do You Need A Vaccine If You Had COVID?


Do you need a COVID 19 vaccine if you have already had COVID-19 infection? Some people that have already had COVID-19 infection may question whether or not they got to be vaccinated because their bodies have already mounted an immune reaction against the coronavirus and COVID-19. Besides, the immune reaction could mean they need to develop a point of protection against COVID-19 infection. Additionally, researchers have found that the majority of people that have contracted the virus develop neutralizing antibodies which will render the virus harmless.

Nevertheless, immunologists and vaccine experts suggested that people who have recovered from COVID-19 should get vaccinated. Why? One of the main reasons why experts suggest everyone should get COVID-19 vaccine, including those who have had COVID-19, is because everyone’s immune system responds differently to the particular virus. That is why it is said that people who have been infected with the novel coronavirus still should get the vaccine in order to level out the variability in immune responses.  COVID-19 vaccines offer a more consistent level of protection against the pathogen. 

However, there are some unknowns whether COVID-19 vaccines will boost a person’s natural immune response to COVID-19 infection after an initial infection. Despite that matter, a vaccination against Covid-19 likely would not cause harm to people who have already been infected with the virus and there may be some potential benefits. Hence, to be safe, it is recommended that people who have had COVID-19, to receive vaccination. 

According to Centres of Disease Control and Prevention (CDC), you should be vaccinated regardless of whether you already had COVID-19. This is because experts do not yet know how long immunity lasts after recovering from COVID-19. 

In general, when humans are exposed to a pathogen, such as the SARS-CoV-2 virus that causes COVID-19, immune cells called B-cells and T-cells become activated and respond ultimately to help in destroying the pathogen. B-cells and T-cells are also known as lymphocytes. B-cells produce antibodies that can stop viruses from infecting other cells and mark them for destruction by other immune cells. Meanwhile, T-cells destroy virus-infected cells directly and at the same time, helps in developing the production of antibodies. As part of this process, B-cells and T-cells also produce memory cells that remain in the body and are aimed to recognise and respond to that same pathogen, should they ever encounter it once again.

However, reinfections after recovering from COVID-19 infection have been reported, which means that having had COVID-19 is no guarantee to not catch it again. This is why it is suggested for those who have already had COVID-19 to get vaccinated as well. Even if you have already recovered from the disease, it is possible to be infected with the virus that causes COVID-19 again. Despite the natural infection that might function an effective prime, some experts thought that the vaccine acts as a boost for adequate protection from COVID-19 infection. 

When Should You Get The Vaccine If You Already Had COVID-19 Infection?

So, when should you get vaccinated if you have COVID? There is not a set number of days someone should wait until getting the particular vaccine, you should monitor your symptoms and make sure that you are not experiencing any severe COVID-19 symptoms, including a fever. Therefore, If you are eligible to receive the COVID-19 vaccine, it is important for you to take it. Recent research done by pharmaceutical companies suggest that vaccines provide better, longer and positively more consistent protection than innate immunity.


Do You Have To Take Both Doses Of The Vaccine?

It is important to receive both doses of COVID-19 vaccine if you are getting a type of vaccine that is administered in two parts. The vaccines were studied under the prediction of two doses, hence, the effectiveness applies as long as people take both doses. The initial dose offers some protection, but health experts still do not know how long that protection will last.
