Hansoti said Delta variant infections in India and the U.S. come with all the samesymptoms of the original Sars-CoV-2 virus, just more severe. .
A new study from Public Health England showed two doses of the Pfizer-BioNTech vaccine were 88% effective against symptomatic disease from the Delta variant, and even more successful at preventing hospitalization and death. The study, however, found one dose of the Pfizer vaccine was only 33% protective.Jonathan Baktari, CEO of e7 Health a health care and wellness company, said the Delta variant is a testament to why it's important to get both doses of the vaccine.Vaccines against variants: Johnson & Johnson COVID-19 vaccine protects against virus variants, study shows.The CDC says coronavirus variants are the result of changes to the virus' genes.Baktari said the biggest threat with the Delta variant is its ability to infect easily and quickly"It's the confluence of all of these things, decreasing restrictions and then a highly transmissible variant with increased severity of illness on a platform of a burned-out, overstretched health system, which could potentially be a chaotic third wave for America," Hansoti said"If not, after the Delta variant, another variant will just come and surge again."
