COVID-19 reinfection likely for unvaccinated, study suggests

TEXT
New modeling estimates suggest natural immunity from a COVID-19 infection fades quickly, leaving individuals susceptible to reinfection, according to a study published Oct. 1 in The Lancet Microbe.
Researchers at New Haven, Conn.-based Yale School of Public Health and Charlotte-based University of North Carolina analyzed data on seven types of coronaviruses, including SARS-CoV-2, the virus that causes COVID-19. They used this data, along with their knowledge of evolutionary principles, to model the risk of COVID-19 reinfection among unvaccinated people.
Under endemic conditions, the model projected reinfection would likely occur between three and 63 months after peak antibody response, with the median time being 16 months.
"Reinfection can reasonably happen in three months or less," lead author Jeffrey Townsend, PhD, the Elihu Professor of Biostatistics at the Yale School of Public Health, said in a news release. "Therefore, those who have been naturally infected should get vaccinated. Previous infection alone can offer very little long-term protection against subsequent infections."
Researchers also predicted reinfection will become "increasingly common" as COVID-19 transitions into an endemic disease.

I am not a scientist, nor medical professional, but this article contradicts itself. The essence appears to be that reinvention will likely occur and it could happen at any time. WOW.

Sir, it speak to two separate periods, one being as I recall 3 months to 63 months for reinfection, the other essentially says immediate to 3 months.
I hope I read it correctly.

The last time they used a model to project is was way wrong! Two if their so called study were true where is the data on those that have been fully vaccinated and have caught and spread covid twice in a six month period. The shot don’t work! Have several fully vaccinated neighbors that have caught Covid multiple times since the second shot!CSM Darieus ZaGara
