Novel Coronavirus: What Are the Different COVID-19 Vaccines You Should Know?


In 2022, the COVID-19 pandemic entered its third year. The Omicron variant and other types of sub-variants are affecting many people in the United States, especially the individuals who have not gone through the vaccination process. Not to mention, the variant is also causing issues to the people who have taken vaccination. Fortunately, the vaccines for COVID-19 are still highly effective at preventing severe diseases from affecting our lives as well as death and hospitalization from COVID-19.

In the United States of America, all infants, children, and adults are eligible for COVID-19 vaccination. As the SARS-CoV-2 is mutating and launching new variants rapidly, it’s extremely important to know about the COVID-19 vaccines as well as their performance.

What are the Symptoms of COVID-19?

If you already received the COVID-19 vaccine, you might not be able to witness any symptoms of the virus due to the effectiveness of the vaccine. The symptoms can be mild or severe, depending on the health condition of the affected person. People who haven’t undergone the COVID-19 vaccination process will undoubtedly suffer from more serious symptoms. Here are the symptoms you need to look for if you think you have coronavirus:

If you have COVID-19 symptoms that are severe, you need to dial 911 and get admitted to a hospital as quickly as possible. But if the symptoms are not severe but mild, consider contacting your primary care provider. If you have dehydration, breathing problems, or a high fever, make sure you go through the COVID-19 tests. If you’re vaccinated, the symptoms might not come. Even if they do appear, they won’t cause serious health issues.

Why There Are So Many COVID-19 Vaccines?

Typically, medical professionals and researchers pay close attention to the vaccine candidates so that they can be proved both effective and safe. For instance, all the vaccines that are present on the market have studies on lab animals. As per reports, less than 1% is effective enough to move into clinical human trials. Upon human trial, one in five vaccines will prove to be successful. As there are lots of different types of vaccines that are in development, the citizens of the United States don’t need to worry about the vaccination process. Here are the different types of vaccines in the United States you need to know.


In August 2021, the Pfizer-BioNTech vaccine was approved by the FDA to be used on people ages 16 and above. The Pfizer-BioNTech vaccine was the first COVID-19 vaccine that received FDA Emergency Use of Authorization in December 2020, after the company stated that the vaccine was extremely effective at preventing illnesses. The Pfizer is an mRNA vaccine. Therefore, medical administrators need to store this vaccine at a freezing level temperature. This is why the distribution of this vaccine is harder in some countries.

People aged 16 or older are eligible under EUA to take the COVID-19 vaccine. Children and infants aged between 6 months and 15 years can also take this vaccine shot. Medical administrators need to provide two shots of this vaccine 21 days apart. According to MyBioSource, they will become fully effective after someone receives the second dose. However, keep in mind that the dosage for children is different than for adults. Some people who are older than 12, especially men and boys between the age of 12 and 39 should follow an 8-week interval between the two dosages of this vaccine so that they don’t suffer from any side effects. After people complete the two doses, they need to take a booster after 5 months.


FDA also granted access to Moderna to be used as a COVID-19 vaccine for people who are 18 or older. The Moderna is based on the same advanced level technology as the Pfizer-BioNTech and that is mRNA technology. This vaccine is also capable of preventing symptomatic diseases and they need to be stored at a freezing level temperature.

In the United States, children, infants, and ages 6 months or older are also eligible to take this vaccine shot. Just like Pfizer, there are two shots in the primary series of the vaccination. The dosage for children is different than that of adults. The men and boys between the age of 12 and 39 should also follow the eight-week interval like the Pfizer to reduce the risk of myocarditis, one of the most common side effects of the COVID-19 vaccine.

However, keep in mind that the Moderna vaccine comes with different side effects such as redness, pain, and swelling in the area where the shot has been administrated. People can also suffer from fever, muscle pain, nausea, and chills after taking the vaccine. Even if these side effects occur, they will go away within a couple of days.
