It's funny how they don't point out the obvious, that having the COVID, gives broader protection than just the "manufactured spike protein" defense.
A casual or sloppy reader would miss the point completely.
from the "full text"
The suggested high protection (91%-94% depending on level of community spread) by a previous infection in our study is in line with recently published studies. A study from Denmark suggested an overall protection against reinfection of 81% during the second surge of the COVID-19 epidemic, but with markedly diminishing protection of individuals ≥65 years old . Among health care workers in UK the estimated protection of a previous infection was 94% against a probable or possible symptomatic infection and 83% against all probable and possible infections (our calculations based on reported odds ratios) .
The study has basically aligned with the "science" before Covid-19.
- The human body will build immunity when exposed
- People with weakened immune systems will fair poorly
- The young and healthy have little fear.
- Outdoor transmission is rare and difficult.
- The longer a person is closely exposed (less than 3 feet not 6), such as families and roommates forced to lockdown in small apartments or people in healthcare facilities, the better chance they will contract it.
- Casual exposure can cause the body to produce anti-bodies even if the person is asymptomatic.
- Cloth masks/paper do nothing to reduce transmission.
- Infection from surfaces is rare.
