10 Best Clinics for Covid-19 Vaccination in Amman [2021 …

When you receive a COVID-19 vaccine, you should still wear a mask that covers your nose and mouth unless you cannot wear one for a disability or health reason. Make sure to stay 6 feet away from others while you are waiting in line to get the vaccine.

Before the medical staff injects the vaccine, you will be asked some questions about your medical history. Tell the staff if you are pregnant, have ever had a severe allergic reaction, or have certain medical conditions. You will then be given an injection of the vaccine into your upper arm. Most COVID-19 vaccines require more than one injection, so you will be asked to return to the facility for another injection between three to four weeks following the first one, depending on the COVID-19 vaccine used. It is important to have both injections of the same vaccine to get the best protection. The first injection should give you adequate protection from the virus. Still, you do need to have two injections of the vaccine to get full and longer-lasting protection. Unless your doctor or a provider tells you not to get a second shot, make sure to get the second shot even if you have side effects from the first one.

There are currently more than 200 candidates of COVID-19 vaccines in development and clinical trials worldwide. Some have produced very positive results in phase III clinical trials. As of December 2020, several vaccines have been authorized and recommended to prevent COVID-19 in various countries. These are:

Pfizer/BioNTech Vaccine

Pfizer/BioNTech COVID-19 Vaccine has been given emergency use authorization by the FDA (the United States Food and Drug Administration) and the MHRA (the Medicines and Healthcare products Regulatory Agency). Data has shown that this vaccine is 95% effective at preventing COVID-19 in people without evidence of the previous infection. This vaccine requires two injections, which are given 21 days apart. It is delivered through shots in the muscle of the upper arm. Pfizer/BioNtech Vaccine is for people age 16 and older.

Moderna Vaccine

Like the Pfizer/BioNTech COVID-19 Vaccine, Moderna COVID-19 Vaccine has also been given emergency use authorization by the FDA and the MHRA. Evidence from clinical trials has shown that this vaccine has an efficiency rate of 94.1%. The Moderna COVID-19 vaccine is recommended for people aged 18 and older. It needs two injections, one month (28 days) apart, and is given through shots in the upper arm muscles.

Both the Pfizer/BioNTech and the Moderna vaccines use messenger RNA (mRNA). mRNA vaccines teach our cells how to create a protein that can trigger an immune response inside of the body. This immune response produces antibodies, which protect us from getting infected if the virus enters our bodies.

AstraZeneca Vaccine

AstraZeneca COVID-19 Vaccine, or Oxford-AstraZeneca COVID-19 Vaccine, was approved by the MHRA on 30 December 2020 but has not been submitted application for emergency use authorization in the US. Data from clinical studies have shown that AstraZeneca Vaccine is 70% effective in protecting people from getting infected. It requires two injections, given four weeks apart.

Unlike the Pfizer/BioNTech and Moderna Vaccines, AstraZeneca Vaccine is a viral vector vaccine. It is created from a weekend version of a common cold virus (called adenovirus) that has been modified to look more like the coronavirus. When the AstraZeneca vaccine is injected into our body, it prompts our immune system to begin creating antibodies, which attack SARS-CoV-2 infection.

CoronaVac

Besides these three, another COVID-19 vaccine that has been approved by many countries is the CoronaVac, which was developed by the Chinese biopharmaceutical company Sinovac. At this point in time, it is hard to say exactly how effective the Sinovac vaccine is. A late-stage trial in Turkey shows that the vaccine was 91.25% effective, a clinical trial in Brazil says that the vaccine was 78% effective, and Indonesia says that the vaccine is 65.3% effective. It is an inactivated whole virus vaccine that works by using killed viral particles to expose our bodys immune system to the virus without risking a serious response. It triggers our bodies to produce an immune response that will protect us against infection.

As of January 2020, Brazil, Turkey, and Indonesia have signed an agreement with Sinovac to buy the CoronaVac. Ukraine, Singapore, Thailand, Hong Kong, the Philippines, Bolivia, and Chile have also authorized the use of CoronaVac or struck supply deals with Sinovac.

Sputnik V

Several countries, such as Argentina, have also authorized Sputnik V for emergency use. Also known as the Russian vaccine, Sputnik V is developed by Gamaleya Research Institute of Epidemiology and Microbiology.
