The coronavirus pandemic is rapidly transforming our lives in ways that we cannot imagine.
With vaccine rollout plans in full swing across the world, the race to vaccinate citizens and prevent the spread of the virus has become increasingly urgent. To ensure that individuals can best protect themselves and their loved ones, many are wondering, “How long does the COVID-19 vaccine last?” This article will provide an in-depth look at the various types of coronavirus vaccines and their anticipated longevity.
Types of COVID-19 Vaccines
There are two main types of COVID-19 vaccines being developed and deployed around the world: messenger RNA (mRNA) vaccines and viral vector vaccines.
- mRNA Vaccines
mRNA vaccines are new and highly advanced vaccines used to develop immunity against the novel coronavirus. mRNA vaccines are created using mRNA molecules that give instructions to the body’s cells to make a copy of the virus’s spike protein. By creating spikes on the cell’s surface, the immune system can recognize the virus and create immunity.
These types of vaccines are currently being developed and distributed by companies such as BioNTech, Moderna, Pfizer, Johnson & Johnson, and CureVac. mRNA vaccines have been found to produce a strong antibody response in the body against the virus and have little to no risk of adverse side effects.
- Viral Vector Vaccines
Viral vector vaccines are created by taking a harmless version of a virus, such as a weakened cold virus, and altering it to contain a portion of the virus that causes COVID-19. This virus is then introduced into the body, which in turn creates an immune response against the virus.
The three most popular viral vector vaccines are being developed by companies such as AstraZeneca/Oxford, Sinovac, and CanSino. Although these vaccines have not been proven to be as effective as the mRNA vaccines, evidence suggests that they can still greatly reduce the risk of transmission and severe illness caused by the virus.
How Long Do COVID-19 Vaccines Last?
Now that we have a better understanding of the different types of COVID-19 vaccines, let’s take a look at how long they are expected to last.
- mRNA Vaccines
The mRNA vaccines have been found to provide strong levels of immunity that remain effective for up to 3-6 months after the initial dose. However, as research into the vaccine is still in its early stages, scientists are continuing to monitor and study the longevity of the vaccine’s effectiveness beyond this timeframe.
- Viral Vector Vaccines
The viral vector vaccines have not been found to be as effective as the mRNA vaccines. That being said, evidence suggests that these vaccines can still provide reasonably effective immunity that lasts up to 6-12 months after the initial dose. Again, further studies are needed to determine the exact duration of immunity that the vaccine provides long-term.
Importance of Booster Shots
Regardless of which type of COVID-19 vaccine you receive, it is important to get a booster shot to ensure strong and lasting immunity against the virus. Booster shots are an additional dose of the vaccine administered after the original dose to help boost antibody levels in the body and enhance the individual’s immunity.
Most medical professionals recommend getting booster shots between 3-6 months after the initial dose to ensure lasting protection. In addition, individuals may need to get a booster shot sooner if the initial dose does not provide enough immunity or if the virus mutates significantly over time.
The COVID-19 pandemic has taken the world by storm and is rapidly changing the way we live our lives. To protect ourselves and our loved ones, it is essential that we get vaccinated against the virus. With vaccine rollout plans in full swing across the world, individuals are wondering, “How long does the COVID-19 vaccine last?” In this article, we explored the different types of vaccines available and discussed the expected duration of immunity that they can provide.
Since the coronavirus is constantly mutating, the best way to ensure strong and lasting immunity against the virus is to get a booster shot between 3-6 months after the initial dose. If you have any further questions or concerns regarding the coronavirus vaccine, be sure to speak to your medical professional.
