How Far Do the COVID-19 Vaccines Protect You?: To combat the extraordinary COVID-19 pandemic, innovative vaccines to protect humans against the SARS-CoV-2 virus that causes COVID-19 have been created.
The Food and Drug Administration (FDA) has approved three vaccinations for use in the United States at this time: How Far Do the COVID-19 Vaccines Protect You can be judged from the following.
- Moderna (mRNA-1273)
- Pfizer-BioNTech is a joint venture between Pfizer and BioNTech (Comirnaty)
- Johnson & Johnson is a pharmaceutical company based in the United States (Janssen)
The following vaccinations have not yet been licensed for use in the United States:
Many people are concerned about how long the immunizations will last — whether they will provide lifelong protection, such as the mumps vaccine, or whether they would require periodic doses, such as the flu vaccine.
How Far Do the COVID-19 Vaccines Protect You. The answer to this topic is complex and under investigation, with numerous elements influencing research outcomes, including the number of participants, study timing, and participant health.
However, data is increasingly showing more detailed efficacy numbers for all five vaccinations currently in use around the world.
Here’s what the evidence shows about the most widely used COVID-19 vaccines and how long they stay.

How Far Do the COVID-19 Vaccines Protect You?
Knowing how long your vaccine will protect you can give you more confidence in making long-term plans, such as returning to a physical workspace or classroom, or attending public events.
On December 18, 2020, the Moderna vaccine was licensed for use in the United States. It’s also been approved for usage in a number of additional countries, as well as within the European Union.
After receiving FDA emergency use authorization (EUA) for 12 to 17-year-olds in August 2021, the Moderna vaccine is indicated for adults aged 12 and up.Here are some crucial facts and data about the Moderna vaccine, including its efficacy as determined by the most recent studies.

Moderna: The Most Important Facts About Efficacy
Efficacy: According to Trusted Source, the Moderna vaccination is 94.1 percent effective in preventing COVID-19. How long does immunity last? According to studies, immunity lasts at least 6 months.
In May 2021, Moderna discovered that a second dose of the vaccine followed by a booster shot is effective against the Beta and Gamma strains.
Moderna was proven to be up to 85% effective against the Delta variation in a preprint research published in August 2021.
How it works is as follows:
The Moderna vaccine is an mRNA vaccine (messenger RNA vaccine).
mRNA vaccines, unlike traditional vaccines, which inject a small quantity of dormant virus into a person, employ a portion of genetic coding from the virus itself that enters your body.
On December 11, 2020, the Pfizer-BioNTech vaccine was licensed for use in the United States.
It’s also sold under the name Comirnaty throughout the European Union, as well as in a number of other countries around the world.
Anyone over the age of 12 is presently advised to get the immunization.
Here are some crucial data and information about how the Pfizer-BioNTech vaccine works and how successful it is.
Pfizer-BioNTech: Key efficacy facts
Efficacy: Research: According to Trusted Source, the vaccination is around 95% effective in preventing COVID-19.
Immunity: Immunity is expected to continue at least 6 months, according to studies.
Protection against virus: The vaccine appears to be successful in preventing the Beta version, according to research. According to a research published in July 2021, the vaccination was 88% effective against the Delta version and 93.7 percent effective against the Alpha variant.
How it works is as follows: The Pfizer-BioNTech vaccine, like the Moderna vaccine, is an mRNA vaccine.
It works by injecting a small bit of the virus’s genetic material into your body.
This instructs your body on how to combat the virus while also protecting you against infection.
- You’ll need two doses, separated by 21 days.
- When you become immune: 2 weeks after your second dose.
Johnson & Johnson (Janssen)
On February 27, 2021, the Johnson & Johnson vaccination was licensed for use in the United States.
Concerns about the vaccination causing blood clots halted distribution in April 2021. However, the FDA stated. Trusted Source on April 23, 2021 that the vaccination was still considered safe for most patients and may be administered. This vaccine is widely used in adults aged 18 and up, including in the European Union under the brand name Janssen.
Here are some essential details about the Johnson & Johnson vaccine’s efficacy and operation.
Johnson & Johnson: Key efficacy facts
• Its effectiveness:
The vaccination has been demonstrated to be 66.3 percent effective against COVID-19, according to Trusted Source.
According to studies, the vaccine is 85 percent effective against COVID-19-related serious disease.
• How long does immunity endure? According to two pre-print studies published in July 2021, protection against COVID-19 should last at least 8 months.
• Anti-variant protection:
Early tests of the vaccine have showed that it is very likely to be effective in protecting recipients from variations.
• How does it work?
The vaccine is an antivirus vector vaccine, which uses a lab-created inactive antivirus (the cold virus) as a shell for SARS-CoV-2 virus spike proteins.
When the shell virus infects your computer, it also infects your files.
- How many doses you need: One
When you become immune: 2 weeks after a single dose.
Although the Oxford-AstraZeneca vaccine has not been licenced for use in the United States, it is available in the United Kingdom, Canada, Australia, the European Union, and dozens of other countries across the world.
Vaxzevria is the brand name for the vaccination in several countries.
Adults aged 18 and up are advised to use it.
Here are some significant statistics about the effectiveness of the Oxford-AstraZeneca COVID-19 vaccine.
Oxford-AstraZeneca: Key efficacy facts
• Efficacy: In clinical trials, the vaccine was found to be 77% effective against COVID-19 and 100% effective against serious sickness caused by the virus.
• How long does immunity last? Trials are currently underway to see how long this vaccine’s protection lasts, although data suggests that efficacy drops by roughly 10% 90 days after the second dosage.
• Anti-variant protection:
According to a study published in April 2021 by Trusted Source, the vaccination is effective against the Alpha version.
The vaccine was determined to be at least 67 percent effective against the Delta variant in a pre-print testing conducted in August 2021.
• How it works: The vaccine is based on the same adenovirus vector technology as was used in the Johnson & Johnson vaccine.
COVID-19 proteins are carried by an inactive adenovirus shell generated in the lab.
The virus can’t multiply and make you sick once it’s inside your body.
Rather, it instructs your cells on how to combat COVID-19.
• How many dosages do you require:
Two doses, separated by 4 to 12 weeks
•15 days following your second treatment, you will be immune.
Novavax is still in clinical studies and has yet to be licensed for distribution in any nation.
The vaccination will be recommended for people aged 12 and up whenever it is approved.
Here are some critical statistics about the Novavax vaccine’s projected effectiveness.
Novavax: Key efficacy facts
• Efficacy: This vaccine is estimated to be 89.7% effective in preventing COVID-19 and 100% effective in preventing serious disease.
• How long does immunity persist? Trials are currently underway to see how long this vaccine’s immunity will stay.
According to a Novavax announcement from August 2021, a booster shot given six months after the second dose provided immunity that was more than four times stronger than the initial two doses.
• Variation protection: In trials, the vaccination was found to be 86.3 percent effective against the Alpha variant.
• How Novavax works: Novavax is a protein adjuvant vaccine.
Rather than using an adenovirus vector or mRNA vaccine, this vaccine uses nanoparticles produced from SARS-CoV-2 proteins.
These particles will not make you sick, but they will assist your body prepare to combat COVID-19.
• How many doses are required: Two dosages, separated by 21 days.
• 2 weeks after your second treatment, you will be immune.
In trials, all vaccines now approved for use in the United States and internationally were found to be both safe and efficacious.
The majority of vaccine side effects are minor and go away within a day or two.
The length of time that the immunizations will confer immunity is still being researched.
The vaccines developed by Moderna and Pfizer-BioNTech appear to confer immunity for at least 6 months.
As more people are vaccinated, more and more detailed information will become available.
