COVID-19 Immunity After Infection: How It Works and How Long It Can Last

Many wonder if recovering from COVID-19 provides long-term immunity. While research is ongoing, studies suggest immunity lasts 5 to 7 months, with potential for longer protection.

How Does Immunity Work?

When infected, your immune system fights the virus using:

  • T Cells – Destroy virus-infected cells.
  • B Cells & Antibodies – Create antibodies to neutralize the virus.

After recovery, antibodies remain in your system, reducing reinfection risk. However, immunity duration varies.

Can You Get COVID-19 Again?

Yes. Immunity wanes over time, and new variants may bypass natural defenses. Other coronaviruses, like MERS, provide years of immunity, but COVID-19 data is still evolving.

Should You Get Vaccinated After Infection?

Absolutely! Vaccination strengthens immunity, protects against variants, and extends protection.0
