The researchers found that people with no prior COVID-19 infection who then had Omicron showed enhanced immunity to previous variants but a reduced boosting against the Omicron spike protein itself. Historical data on other infectious agents had suggested waiting two to four weeks after a viral infection before getting a viral vaccine since the immune system is ramped up and the protection from the vaccine is likely to be less effective, he added.
