With the third dose of the vaccine, protection against Covid increases up to 44 times.

Immunologist Anthony Fauci said this on video to the Congress of Fadoi internist doctors in Florence: "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), 32 times compared to the B.1.351 mutation (South African) and 44 times compared to the P.1 mutation (Brazilian). Data similar to those detected for the Pfizer booster and indiscriminately in young and elderly, in which there have been drastic increases in antibody levels and protection from severe forms and infections ".

The transmissibility of the Delta variant, he continues, “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 ".

As for the effects of Long Covid "there are also post Covid-19 conditions attributable to residual dysfunction of the organs, 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, weeks to months, that 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 very curious condition called 'brain fog', which causes people to have difficulty focusing or concentrating their thoughts.
