According to the CDC (Centers for Disease Control and Prevention), over 96 million vaccines have been transported to healthcare centers in the U.S. According to experts, about 70% to 90% of people need to be immunized to attain herd immunity. Reaching at this point will depend on the speed of the manufacturers and those who will deliver the vaccines.
After a shaky beginning, vaccination campaigns for COVID-19 have been speeding up in several communities across the country. To achieve immunity, there must be enough people in America who are immune against the coronavirus.
Three Authorized Vaccines
The FDA (Food and Drug Administration) has authorized three brands of COVID-19 vaccines.
Last December, FDA approved the Pfizer-BioNTech vaccine for use in individuals who are 16 years old and older. For people who are 18 years and older, the Moderna shotis administered. Both of these vaccines need two doses and are considered 90% effective at COVID-19 prevention. Also, they are administered several weeks apart.
Just recently, the FDA authorized Johnson & Johnson to release their vaccine to the public known as Janssen Biotech. This vaccine requires only a single dose and is 65% effective in preventing moderate and severe coronavirus cases.
As the supply of shots grows, authorities in public health and private sectors must continue to improve how they distribute the supplies.
