Different Vaccines Available in the US

Currently, there are only three vaccines that are available in the US and approved by the FDA.

On December 11, 2020, this became the first COVID-19 vaccine to get an FDA EUA after the firm revealed favorable clinical trial data, which included news that the vaccine was up to 95 percent effective at avoiding symptomatic illness. However, the Pfizer-BioNTech vaccine has tight storage requirements.

The firm submitted additional evidence to the FDA in mid-February proving the vaccine’s durability at temperatures more typically seen in pharmaceutical refrigerators and freezers. Approval would make it simpler to distribute the vaccine.

In individuals who had never been infected with COVID-19, the vaccine had a 95% effectiveness rate. According to the researchers, the vaccination was equally effective across a wide range of persons and factors, including age, gender, race, ethnicity, and body mass index (BMI)—or the existence of other medical problems.



This is the second vaccine to be authorized by the FDA after Pfizer-BioNTech.

There are two significant differences: The Moderna vaccine may be transported and kept in long-term storage at ordinary freezer settings for up to 30 days, making it easier to distribute and keep. In addition, among clinical studies, the Moderna vaccination was somewhat less effective—about 86 percent—in those 65 and older.

In patients with no history of COVID-19 infection, it is 94.1 percent effective at avoiding symptomatic infection. In clinical studies, the vaccine proved to have excellent effectiveness across people of all ages, genders, races, and ethnicities, as well as those with underlying medical problems.


Johnson & Johnson

The FDA granted an emergency use permit for a distinct form of vaccination, known as a carrier, or viral vector, vaccine, on February 27, 2021.

Compared to the Pfizer and Moderna vaccines, this one is easier to keep (in the refrigerator) and only requires one injection, making it easier to distribute and give. According to an analysis issued by the FDA in late February, the vaccination may help to decrease the transmission of the infection among vaccinated persons.

As for the vaccine, effectiveness has an overall 72 percent efficacy and 86 percent against severe cases.



How Fast Does Immunity Work?

Because of biological limits, vaccinations do not provide instant protection. According to published data on symptomatic illnesses, the Moderna and Pfizer vaccines appear to provide the best protection from 14 to 28 days following both doses.

During the Phase 3 studies, the endpoint protection against symptomatic infection was evaluated two weeks after the second injection for Moderna and one week after the second shot for Pfizer. Moderna would be 42 days, and Pfizer would be 28 days.

That isn’t very different from J & J. After 28 days, it was 85 percent protected from severe illness. After 49 days, it was 100 percent protected.



Side Effects

All three COVID-19 vaccines now in use in the United States can produce short-term adverse effects in some persons, including discomfort at the injection site, tiredness, headache, muscle, and joint discomfort.

These are signs that the immune system is working overtime, which is a good thing; nevertheless, they do not imply that the vaccinations are unsafe.

Whatever you get, there will very certainly be additional COVID-19 vaccinations in your future. Many experts believe booster injections will be necessary; however, whether they would be necessary yearly or every few years is unknown. COVID-19 hasn’t finished with us, and we haven’t finished with COVID-19.

And the best course of action is to do your best to prepare for a series of fatigue, exhaustion, fever, and pain due to the process of developing immunity.
