The Johnson & Johnson vaccine was found to be 85 percent effective against severe forms of COVID-19, which prevents hospitalization and death, per the FDA. The Pfizer-BioNTech and Moderna vaccines have a slight edge in efficacy both report being about 95 percent effective against COVID-19 after the second jab in clinical trials. The World Health Organization (WHO) recommends continuing with inoculations while the concerns are investigated as a precautionary measure. It is unclear if the events are related, and more research is needed to confirm direct causation. The European Medicines Agency insists that the vaccine is safe, citing 30 reported cases of blood clots among five million people given the AstraZeneca vaccine across Europe. However, at least 10 European nations and Thailand either slowed or suspended AstraZeneca vaccinations on March 12 after sporadic reports of blood clotting in people who had received the jab.
These include potential injection site pain and flu-like symptoms: fever, fatigue, headaches, and muscle pain. Pfizer's costs about 20 dollars per dose, Moderna's costs between 25 to 37 dollars per dose, while Johnson & Johnson's costs about 10 dollars per dose, according to Forbes.Īll four vaccines' side effects are similar. providers about four dollars per dose, per a 2021 BMJ report. Being able to use a typical fridge "allows time for distribution, allows the vaccine time to get to more rural areas, to be kept at a clinic for a longer period of time." CostĪstraZeneca's vaccine is estimated to cost U.S. "A clinic, a nursing home, or even health departments may not have freezers that can hold things at -34☌," says Kawsar Talaat, M.D., an infectious disease doctor, vaccine researcher, and assistant professor in the Department of International Health at Johns Hopkins University. Higher storage temperatures could make distribution much easier. The mRNA tech is relatively more fragile, meaning it must be kept at much lower temperatures to remain effective and stable. The Moderna and Pfizer options, however, must be stored at sub-zero temps until they're ready to be used, at -20☌ and -34☌ respectively. The vaccines from Johnson & Johnson and AstraZeneca are the easiest to transport so far - they can be stored for up to six months between 2☌ and 7☌, which are normal refrigerator temperatures. Both approved vaccines require two shots spaced about a month apart.

The Pfizer-BioNTech and Moderna vaccines, meanwhile, rely on mRNA technology, which essentially introduces a piece of genetic code that tricks the body into producing COVID-19 antibodies, with no virus required. Johnson & Johnson's vaccine also relies on similar adenovirus-vectored technology.
The reason researchers chose a chimpanzee adenovirus is that the modified virus needs to be new to the people being vaccinated, otherwise the body won't create those all-important, unique antibodies.
In other words, AstraZeneca's vaccine mimics a COVID-19 infection without its life-threatening side effects, according to the company.

This allows the immune system to manufacture antibodies that work against COVID-19, teaching your body how to respond should you become infected. This altered virus can't make you sick, but it carries a gene from the novel coronavirus' spike protein, the portion of the virus that triggers an immune response. This is a harmless, modified version of a common cold virus that usually spreads among chimpanzees. The AstraZeneca vaccine uses adenovirus-vectored technology. Let's take a look at how they compare to one another: Astrazeneca, how does the vaccine work ? Food and Drug Administration (FDA) so far: Pfizer's, Moderna's and Johnson & Johnson's. However, three other COVID-19 vaccines have received authorization from the U.S. Country after country is pulling out from the AstraZeneca vaccine scheme as reports of blood clots stain the company's efforts to combat COVID-19.
