Last week, authorization of the Johnson and Johnson Covid-19 vaccine was granted for emergency use around the United States along with Moderna and Pfizer; however, many Americans are questioning the effectiveness of this vaccine versus the others and how Johnson and Johnson vaccine differ from Moderna and Pfizer. 

For starters, the Johnson and Johnson Covid-19 vaccine was made differently. Moderna and Pfizer both used mRNA, or messenger RNA, to develop their vaccines, whereas Johnson and Johnson used a viral vector vaccine. A perfectly safe, well researched, and similar alternative to the mRNA vaccines, the viral vector vaccine delivers a common cold virus to the body with a design similar to Covid-19 cells, to train the body to detect and fight off the Coronavirus. 

This vaccine provides a piece of the genetic code of Coronavirus to prepare the immune system. Despite common misconception, this vaccine does not give the recipient the virus, it only teaches the immune system how to react when confronted with similar viruses carrying the ‘spike’ found in Covid-19 cells. 

This type of vaccine has shown to be about 72% effective, in contrast to the Moderna and Pfizer vaccines, which were found to be about 95% effective. While at first glance, the Johnson and Johnson vaccine might seem less effective, they are quite similar. The new Johnson and Johnson vaccine was tested against several new variants of the virus that were not yet discovered when Moderna and Pfizer vaccines were in trials. Therefore, because this vaccine was tested more, and tested against more types of the virus, the effectiveness of the vaccines are likely to be very similar. 

No Coronavirus vaccine has been found to be 100% effective. The Johnson and Johnson vaccine, found to be 72% effective within the United States, showed that even those who contracted the virus after receiving the vaccination showed significantly less severe symptoms than those who did not receive the vaccine, or those received a placebo vaccine. 

Side effects of the Johnson and Johnson Covid-19 vaccine are extremely similar to those of the Moderna and Pfizer vaccines. Side effects include, but are not limited to injection site pain, nausea, and fatigue.

While there are many similarities to the Pfizer, Moderna, and Johnson and Johnson vaccines, there are also some notable differences, one in particular that makes the Johnson and Johnson vaccine easier to distribute and administer. The Johnson and Johnson vaccine can be stored in refrigerators for travel and distribution, whereas the other vaccines need special cooling conditions for travel. By having more regular traveling conditions, this could make the Johnson and Johnson vaccine easier to distribute throughout the United States, and across the world. 

Because there is no need for dilution, unlike the Moderna and Pfizer vaccines, the Johnson and Johnson vaccine only requires one dose. This one dose vaccine makes Covid-19 vaccination more convenient for Americans. 

All forms of the Coronavirus vaccine thus far have shown to be safe, effective, and have all been FDA approved. According to doctors, those who have the ability to get vaccinated should, regardless of which brand of vaccine they will be receiving. Doctors state that those who are eligible, and wait for a certain vaccine increase their risk of contracting the virus. 

The Johnson and Johnson vaccine is eligible to those over the age of 18. Johnson and Johnson states that they hope to administer 20 million doses by the end of March.
