Covid-19 Update: What Is Hybrid Immunity?

Covid-19 Update: What Is Hybrid Immunity?

The world is getting close to the end of 2021, and the Covid-19 pandemic is not over. With more than 20 months since the first outbreak in Wuhan, the new coronavirus has found its way around the globe. Until vaccines became available, many people got infected and could only get vaccinated after recovering from the illness. Those who suffered from the SARS-CoV-2 infection and later got fully vaccinated with an mRNA Covid-19 vaccine such as Pfizer BioNTech have acquired natural antibodies and antibodies produced after vaccination. In simpler terms, those people have a hybrid immunity, and, according to recent studies, it is beneficial for unvaccinated people who had the infection to get vaccinated. 

 

Vaccination is beneficial for everyone, including those who had the infection in the past

 

The study, published on October 14 in the Science journal, concludes that the best way to ensure long-term protection against all Covid-19 strains is through vaccination. The researchers established differences between the immunity generated by vaccination and the natural immunity generated by the Sars-CoV-2 infection. 

 

Another study published in Nature determined those who got infected and then, later on, got vaccinated with an mRNA Covid-19 vaccine might have more robust protection against the virus. Although researchers worldwide are trying to discover and answer as many questions as they can in the shortest time possible, further research is needed to understand the protection offered by natural immunity versus and reinfection. 

 

Experts worldwide recommend vaccination

 

Medical providers explain that people who got infected in the past are twice as likely to get reinfected than those who are fully vaccinated against the SARS-CoV-2 virus. As the virus evolves and mutates, stronger strains might cause different responses in our bodies, and just because the first time we got infected, we had mild to little symptoms, it does not mean that the second time we will experience the same.
