Hybrid Immunity

Hybrid immunity is the combination of natural immunity acquired from a previous infection and vaccine-induced immunity. According to a new research, hybrid immunity offers the best protection against COVID-19.
The study found that persons who were previously infected with COVID-19 and had a single dose of vaccine later on have 30 times higher antibody levels in the blood than those who received two doses of vaccine but had no natural infection. This can play a significant role in the national vaccine policies as it may save large number of vaccine doses given to the previously infection people. The research conclusion was made after studying anti-spike antibody levels and neutralizing antibody titres in blood samples.
