COVID-19 Vaccine Comparison!

Many Americans want to get back to some type of normalcy, but in order to do that we all need to get vaccinated to help society survive getting infected with a severe coronavirus infection. has the latest COVID-19 Vaccine Comparison, but first we want to remind everyone that we all need to still be safe.

Nobody wants to get COVID-19 nor do they want to be hospitalized. The coronavirus is scary and we all need to enforce social distancing. Just because you are vaccinated does not mean you cannot contract it. Face masks are still very important as well as hand sanitizer and washing hands, sanitizing shopping carts and so on.

However, when it comes to the COVID-19 Vaccines, there are three approved in the US, but now its down to two since the Johnson & Johnson vaccine has been paused due to women 18 – 48 getting blood clots.

There are several vaccines still in the approval process for use in the United States.

Approved Vaccines:

  • The Pfizer-BioNTech and Moderna vaccines have been available to Americans since December.
  • A vaccine developed by Janssen Pharmaceuticals, a Johnson & Johnson company, was authorized in late February.
  • AstraZeneca, working in collaboration with Oxford University, is expected to request authorization from the FDA for their vaccine within a few weeks.
  • Then there is the Novavax vaccine which is expected to follow with its application later in April or May.

How Each COVID-19 vaccine Works:

Many vaccines use weakened or inactivated versions or components of the disease-causing pathogen to stimulate the body’s immune response. However, the vaccines developed by Pfizer-BioNTech and Moderna take advantage of messenger RNA (mRNA), which instructs cells to produce a protein on the surface of the virus. The immune system recognizes those vaccine-triggered spike proteins as invaders and creates antibodies to block future attacks of the virus that causes COVID-19.

The Johnson & Johnson vaccine takes the more traditional approach. Adenoviruses are common viruses that typically cause colds or flulike symptoms. The J&J team used a modified adenovirus that can enter cells but can’t replicate inside them or cause illness. The vaccine contains this modified virus that delivers a spike protein, activating the immune system.

The AstraZeneca-Oxford vaccine also uses an adenovirus, in this case a monkey virus that the human immune system doesn’t recognize. It delivers the gene that encodes the spike protein to human cells rather than the protein itself.

Novavax’s vaccine works by delivering lab-grown spike proteins along with a compound that attracts immune cells to the site of the injection.

At the end of the day, the best vaccine to get is the vaccine that is available to you in your area.
