The global COVID-19 pandemic has captured global attention in the past year.
Medical scientists are working hard to develop an effective vaccine to halt the spread of the global pandemic and help individuals return to their regular lives. With the development of the coronavirus vaccine, the global population has been presented with the opportunity to protect themselves from the threat of the COVID-19 virus while allowing them to resume normal activities. However, with several different vaccine options available, there is confusion and not everyone is sure of which one is the best fit for them. In this article, we will be exploring which Covid vaccine is better.
What is a Covid Vaccine?
A Covid vaccine is a medical product developed to protect people from contracting the SARS-CoV-2 virus, which causes COVID-19 disease. Vaccines imitate the original strain of the virus, which stimulates the body’s immune system to produce antibodies and other virus-fighting defenses. When an individual is exposed to the actual virus, these defenses are triggered to fight it off.
Types of Covid Vaccines
Currently, there are two main types of Covid vaccines available— mRNA vaccines and vesicle vaccines.
Messenger RNA (mRNA) is a type of genetic information that is present inside the cells of living beings. mRNA vaccines are created by introducing this genetic material into the body’s cells to produce proteins that mimic components of the virus. The body then responds to the protein by producing antibodies, which fight off the virus if it infects the body.
Vesicle vaccines also exploit the body’s natural defences to fight off viruses. Rather than introducing genetic material to produce proteins, they contain weakened forms of the virus itself. The produced antibodies bind to the virus, preventing it from entering the body’s cells.
Established Vaccines and Effective Vaccines
Currently, there are two established Covid vaccines— Moderna and Pfizer. Both Moderna and Pfizer mRNA vaccines have been found to be 94-95% effective, and are two of the most popular Covid vaccines.
The following vaccines have also been found to be effective:
• AstraZeneca (79-90% efficacy)
• Novavax (89.3% efficacy)
• Johnson & Johnson (66.3 -72% efficacy)
• Sputnik V (92% efficacy).
Which Covid Vaccine is Better?
It’s difficult to say which Covid vaccine is better due to the diverse factors involved. Each vaccine has its own set of benefits and drawbacks, and it’s important for individuals to carefully consider their needs before deciding which vaccine is best for them.
Benefits and Drawbacks of Different Vaccines
The Moderna vaccine has many benefits. It has been found to be 94-95% effective, and it is administered in two doses, 28 days apart. The vaccine also has a storage temperature of -20°C, and only requires an ordinary freezer to transport and store it. However, a drawback of the Moderna vaccine is that it is a 2-dose vaccine, and individuals have to wait 28 days for the second dose.
The Pfizer Covid vaccine has a similar efficacy to Moderna at 94-95%, and it is also a 2-dose vaccine administered 28 days apart. However, it has a different storage requirement of -70°C, which means it is only available in ultra-cold freezers. Lower temperatures can also increase the cost of distribution and affect the stability of the vaccine.
The AstraZeneca vaccine has an efficacy of 79-90%. It is administered in two doses, but unlike Moderna and Pfizer, the second dose is administered after 3–4 weeks. This is advantageous for individuals who can’t wait up to 28 days for their second dose, as AstraZeneca provides more flexibility in terms of scheduling. It also has the benefit of being a single-dose vaccine for those aged 18-49. The AstraZeneca vaccine does require a storage temperature of 2-8°C, which makes distributing and storing it easier than Pfizer, but more difficult than Moderna.
The Novavax vaccine has an efficacy of 89.3%, and it is also administered in two doses, 3-4 weeks apart. It is also easier to transport than Pfizer, as it requires a storage temperature of -20°C. However, one drawback of the Novavax vaccine is that it takes longer to become effective, and individuals have to wait up to 2 weeks after their second dose before the vaccine is effective.
• Johnson & Johnson
The Johnson & Johnson Covid vaccine has an efficacy of 66.3 -72%, but it is a single-dose vaccine, so individuals don’t have to wait for a second dose. It also offers better protection against severe COVID-19, and has a storage temperature of 2-8°C, which allows for easier transportation and storage. However, it is less effective than the other vaccines.
• Sputnik V
The Sputnik V vaccine has a very high efficacy of 92%. It is administered in two doses, 3-4 weeks apart. It also has a storage temperature of 2-8°C, which makes it easier to distribute. However, it has not been approved for use in the US yet.
Deciding Which Vaccine is Best For You
When deciding which Covid vaccine is best for you, it is important to consider the benefits and drawbacks of each vaccine and determine which one meets your needs. You may need to consider factors such as the efficacy of the vaccine, the length of time you have to wait before the vaccine takes effect, the ease of transportation and storage, and whether the virus has been approved for use in your country. Picking the right vaccine can help safeguard you against the risk of contracting COVID-19 and protect yourself and your loved ones.
The global pandemic of the coronavirus has brought much uncertainty and confusion as to which vaccine option is the best fit for each individual. With several different vaccines available, it can be difficult to decide which one is best for you. This article has provided an overview of the various options available and the benefits and drawbacks of each so that you can make an informed decision as to which Covid vaccine is better for you.
