“However, the current vaccines against SARS-CoV-2 will play a role in how fast the virus becomes endemic, especially if they induce short-lived immunity but reduce the severity of disease upon reinfection. The authors posited that as milder reinfections become more common, reliance on symptoms as a surveillance tool to curb the virus’s spread will become more difficult.”

“The authors of the current study isolated SARS-CoV-2 from nasopharyngeal (roof of the mouth) samples taken from a patient in Sweden who tested positive for COVID-19. Then they infected cultured cells with the isolated virus with or without the presence of hrsACE2.”

“Findings from two new studies suggest that people who are infected with SARS-CoV-2, the virus that causes COVID-19, have T-cells that target the virus. The first of the two studies analyzed blood samples collected 20 to 35 days after the onset of symptoms in 20 non-hospitalized COVID-19 patients who were no longer symptomatic.”

“This is a breakthrough because old methods of turning skin cells into neurons used viruses that are known to cause cancer.”

“Additionally, three different SNPs in the vitamin D receptor are all associated with a higher risk of respiratory tract infections in both adults and children. Vitamin D and the renin-angiotensin-system SARS-CoV-2 virus enters human cells via the ACE2 receptor.”

“A new type of gene editing CRISPR system has been developed that can erase large pieces of DNA from a specific site in the human genome and has the potential to eliminate viruses like herpes simplex, Epstein-Barr, and hepatitis B.”
