RACE FOR IMMUNITY

A familiar storyline:
those vaccinated vs. those not.
But how do those who had COVID-19 figure into the debate?
What To Know & Why It Matters

Current Events

BIG PICTURE:

Beware: No Definitive Answers - Studies on the immunity of vaccinated individuals *and* those who had COVID-19 are limited and ongoing.
  • An estimated 33 million Americans have tested positive for COVID-19; health officials believe the true number is likely higher due to asymptomatic cases.
  • 140+ million Americans have received a full vaccine dose. That amounts to more than 50% of the eligible population (12 & older), including more than 75% of those 65 & older.

Current Events

"The risk of severe illness and death from COVID-19 far outweighs any benefits of natural immunity."

On the CDC's website page "Benefits of Getting a COVID-19 Vaccine," it says reinfection "is uncommon in the months after initial infection, but may increase with time." Health officials believe the vaccine offers a more robust immune response and greater protection against variants. A new CDC study suggests those who received an mRNA COVID-19 vaccine (Pfizer, Moderna) had a reduced relative risk of infection of more than 90%.

Current Events

"It’s time to stop the fear mongering and level with the public about the incredible capabilities of both modern medical research and the human body’s immune system."

Dr. Marty Makary, Johns Hopkins School of Medicine, says there is "ample scientific evidence that natural immunity is effective and durable" to COVID-19 and believes for someone previously infected, "one shot (COVID-19 vaccine) is sufficient, and maybe not even necessary, although it could increase the long-term durability of immunity."

Current Events

Something To Consider:

  • The Dept. of Health in Austin, Texas says an obstacle to community immunity includes those previously infected with COVID not prioritizing receiving the vaccine; concern remains about transmission and variants.
  • A preprint study by the Cleveland Clinic: "Individuals who have had SARS-CoV-2 infection are unlikely to benefit from COVID-19 vaccination, and vaccines can be safely prioritized to those who have not been infected before."

Current Events

A question shared by those vaccinated and those not vaccinated but with prior infection - the strength and length of immunity and ability to transmit the virus. Remember: the very first COVID-19 vaccine administered in the U.S. outside of a clinical trial was Dec. 14, 2020. Meanwhile, clinical trials remain ongoing for the next several years regardless of the emergency use authorization received by Pfizer, Moderna, and Johnson & Johnson.
