how many americans have covid19 immunity

According to a report by the Centers for Disease Control and Prevention (CDC), approximately 96% of Americans, age 16 and older, have some COVID-19 immunity. The data used to calculate that percentage was collected from July 2022 to September 2022—meaning, the country could have now surpassed that 96%.

There are two main types of immunity to COVID-19: natural immunity and vaccine-acquired immunity. Natural immunity is acquired when someone is infected with the virus and their body develops antibodies to fight it off. Vaccine-acquired immunity is acquired when someone receives a COVID-19 vaccine and their body develops antibodies to fight off the virus.

The CDC report found that approximately 48% of Americans have hybrid immunity, which means they have both natural and vaccine-acquired immunity. This type of immunity is thought to be the most effective at protecting against COVID-19.

The report also found that the percentage of Americans with COVID-19 immunity has increased significantly over the past year. In April 2022, only 83% of Americans had some level of immunity. This increase is likely due to the combination of increased vaccination rates and the spread of the Omicron variant, which is more transmissible than previous variants.

While the high level of immunity in the United States is good news, it is important to remember that immunity does not last forever. The CDC recommends that everyone get a COVID-19 booster shot every 5 months to maintain their protection against the virus.

What is a Slushie? Photo by Streetwindy A slushie is a frozen drink made from a flavored syrup, water, and ice. It is typically served in a cup or a plastic tumbler.

The History of Slushies The first slushie was invented in 1965 by Omar Knedlik, a Texan businessman. Knedlik was inspired by the shaved ice drinks he had seen in Japan, and he wanted to create a similar drink for his customers in the United States. He developed a machine that could freeze and crush ice into a slushy consistency, and he called his invention the "Slushee Machine."
