The third dose of coronavirus vaccine can increase protection against Delta strain by almost 100 times. This is stated in a report published by Pfizer.
“The third dose significantly improves the neutralization data of the Delta variant. The expected potential is an increase of up to 100 times in neutralizing the Delta variant after the application of the third dose, ”the document reads.
In addition, it is noted that after the introduction of the third dose of the vaccine in people aged 18 to 55 years, the number of antibodies increases more than 5 times, and in people aged 65 to 85 years – 11 times.
Last week, the head of the US Centers for Disease Control and Prevention (CDC), Rochelle Wallenska, said that the Delta strain currently accounts for 83% of coronavirus infections in the United States, which is 50% more than in early July. In addition, the CDC said on Tuesday that people fully vaccinated against the new coronavirus could rarely tolerate the Delta variant.
