A study published in The New England Journal of Medicine finds natural Covid immunity offers longer lasting protection than vaccination, but a combination of full vaccination and prior infection is maximally protective.
The Omicron variant may confer strong protection against other variants. This has many people wondering whether omicron could act as a vaccine of sorts, inoculating enough people to effectively bring about herd immunity.
The most important thing to understand about vaccines is that they teach your body how to gear up to fight an infection, without your body having to deal with the infection itself. In this way, vaccines help your body be prepared for invasions by germs that could otherwise make you very sick.
