“15 days after the administration of the third dose of the Moderna vaccine compared to more variants we can see a 23-fold increase in protection compared to the D614G mutation (the first relevant compared to the original Wuhan strain), of 32 compared to the B.1.351 mutation ( South African) and 44 times compared to the P.1 mutation (Brazilian). Data similar to those found for the Pfizer booster and equally in young and old, in which there were drastic increases in antibody levels and protection from severe forms and infections “. This was stated by immunologist Anthony Fauci at the Congress of Fadoi internal doctors.
The transmissibility of the Delta variant is much more efficient than the other variants and the viral load in the upper airways of infected people is up to a thousand times higher than other variants. In the United States this has led to a decline in the effectiveness of vaccines against severe forms of the disease with consequent hospitalizations, which is from 91 to 81% for Moderna and from 85 to 75% for Pfizer ‘. This was stated by the immunologist and scientific advisor of the White House Anthony Fauci at the Florence Congress of Fadoi hospital internists, who awarded him the Internal Medicine Research Award 2021. Upon delivery Fauci expressed ‘respect and gratitude to the doctors of Fadoi for their dedication to patients during the pandemic and their simply fantastic expertise. ‘ Fauci then spoke of the Long Covid explaining that ‘there are also post Covid-19 conditions attributable to residual organ dysfunction, due to damage, such as lung damage, which leads to abnormal function. However, about 15 to 30% of individuals have a persistence of signs and symptoms, from weeks to months, which are not fully explainable. Some of those reported as Long Covid are extreme fatigue, sometimes debilitating, unexplained shortness of breath, muscle aches, dysautonomia (nervous system malfunction) characterized by sudden changes in temperature and unexplained tachycardia, sleep disturbances, depression and anxiety, and a condition very curious called ‘brain fog’, which causes people to find it difficult to focus or concentrate their thoughts’.
