As the pandemic is progressing, a crucial concern is to determine how long people exposed to SARS-CoV-2, will make neutralizing antibodies against this virus. Finding the answer is hypothetically complicated as “variants of concern” are appearing around the world that could find ways to dodge acquired immunity, boosting the likelihoods of new outbreaks.
For certain infectious diseases for which there are vaccines, natural infection produces stronger immunity than the vaccine-acquired immunity. On the contrary, in some instances, vaccine-acquired immunity is stronger than natural immunity and vaccines induce a better immune response than natural infection.
Scientists are still discovering about natural and vaccine-induced immunity generated against COVID-19.
