On May 13, 2021, the United States Centers for Disease Control and Prevention revised its mask-wearing standards, leaving many Americans perplexed. Anyone who has been wholly vaccinated can now engage in large and small indoor and outdoor activities without the need for a mask or physical separation. President Biden’s senior medical adviser, Anthony Fauci, said the new recommendation is “based on the progress of evidence” and “serves as an incentive” for the nearly two-thirds of Americans who have not yet been wholly vaccinated to get the shot.
Some people, however, are unable to be vaccinated due to underlying medical issues. Immunizations may not adequately protect immune systems that have been weakened by cancer or medical treatments. Only on May 10, 2021, children aged, 12 to 15 become eligible for the Pfizer-BioNTech vaccination. Furthermore, no COVID-19 vaccinations have been approved for almost 50 million children under 12 in the United States.
Within two months, the number of detectable illnesses among the 4.7 million people who had been adequately vaccinated had dropped by 30-fold. Only 0.05 percent of fully vaccinated healthcare workers in California and Texas tested positive for COVID-19. Vaccine developers frequently hope that, in addition to preventing illness, their vaccinations will provide “sterilising immunity,” in which the vaccine prevents the germ from even entering the body.
