Due to the rapid spread of Covid-19, three Covid vaccines have been quickly made. Pfizer, Moderna, and Johnson & Johnson are the three authorized vaccines.
Most vaccines normally take 10-15 years to develop. It is a long and complex process. However, since Covid has spread very quickly, the vaccines made to prevent Covid have taken less than one year to be made. Because this vaccine was manufactured so rapidly, many people are reluctant to get the vaccine.
The Pfizer vaccine so far is the only vaccine that teenagers 16-18 can take. This shot is for people sixteen and older. You receive two shots that are given three weeks apart. To be considered fully vaccinated, it has to be two weeks after your second shot. The Pfizer vaccine is said to be 95% effective in preventing Covid-19.
Moderna is for people eighteen years and older. The Moderna vaccine has shown about 94.5% effectiveness. Like Pfizer, Moderna is also two shots, but is given four weeks apart instead of three. For Moderna, you are also fully vaccinated two weeks after the second shot.
Johnson & Johnson is the only vaccine made so far that is just one shot. Like Moderna, Johnson & Johnson is for people eighteen and older. You are fully vaccinated two weeks after you get the one shot. The Johnson & Johnson vaccine is only 66.3% effective in clinical trials which is the least effective out of the three vaccines.
On April 2nd, 2021, one hundred million Americans have gotten at least one vaccine shot. As of four days ago, 56 million Americans have been fully vaccinated for Covid. This is only 16.9% of the country’s population.
The three Covid-19 vaccines, Pfizer, Moderna, and Johnson & Johnson have shown to be highly effective in preventing a person from getting Covid, even though these vaccines were produced very rapidly.
