The answer to that debate is complicated, but studies show the best way to protect yourself against the Omicron variant is to get vaccinated and then boosted. An infection on top of that, while ...
When it comes to natural immunity, relying on prior natural infection over vaccination can come at a cost — and it doesn't seem to work currently given the evasive capabilities of Omicron.
Immunity from an Omicron infection for unvaccinated and previously uninfected was found to be weak "against non-Omicron variants", [267] albeit at the time Omicron is, by a large margin, the dominant variant in sequenced human cases. [268]
When it comes to natural immunity, relying on prior natural infection over vaccination can come at a cost — and it doesn't seem to work currently given the evasive capabilities of Omicron.
The Omicron variant, known as lineage B.1.1.529, was declared a variant of concern by the World Health Organization on 26 November 2021. [202] The variant has a large number of mutations, of which some are concerning. Some evidence shows that this variant has an increased risk of reinfection. Studies are underway to evaluate the exact impact on ...

Natural immunity is gained by those organisms whose immune systems succeed in fighting off a previous infection, if the relevant pathogen is one for which immunization is even possible. Natural immunity can have degrees of effectiveness (partial rather than absolute) and may fade over time (within months, years, or decades, depending on the ...
Scientists have warned that a coronavirus variant like omicron, which appears able to dodge some protective antibodies generated by the vaccines, could be a major setback in the pandemic ...
