Before you take a COVID19 vaccine, you need to know how it works. Here we detail everything about the vaccine, including its working mechanism.
During the time you read this article, the news of COVID19 vaccinations going across the world must be doing the rounds in the media.
What is worth noting is that dedicated scientists have developed the vaccines in record time. With the ongoing vaccine administrations, the confidence of controlling the pandemic has at least aroused in the minds of the medical fraternity.
Vaccines develop immunity in people against a virus or other germ. It introduces a less harmful part of the germ that causes the disease in the human body.
Subsequently, the body’s immune system develops antibodies to fight off that particular germ. As a result, the person does not get sick from it. If the person faces that germ again, his immune system can recognize it and fight it off to prevent him from getting infected.
How COVID19 Vaccines Work?
COVID19 causing Coronavirus has protein spikes on each viral particle. With the spikes, the virus sticks to cells and causes the disease. Most of the COVID19 vaccines enable the human body to recognize the spike proteins and fight off the Coronavirus.
The vaccine lowers the chances of getting a COVID19 infection if the person gets exposed to Coronavirus. It prevents hospitalization and death.
When there is a widespread COVID19 vaccination, the Coronavirus will no longer infect many people. It will also restrict the virus from mutating into new variants.
How Many Doses of COVID19 Vaccine Do You Need to Take?
The number of doses depends on the brand. While Pfizer’s and Moderna’s vaccines require two doses, Johnson & Johnson’s vaccine requires only one dose.
You need to take Pfizer’s second dose after three weeks after the first dose and Moderna’s second dose after four weeks after the first dose.
What Can Happen if there is a Delay in the Second Dose?
There can be happenings that can prevent a person from receiving the second vaccine at the right time. In such a case, the person can extend the timeline up to 42 days following the first dose. Clinical trial data serves as the evidence supporting the extended timeline.
Bear in mind that there is hitherto limited data on the efficacy of mRNA COVID19 vaccines administered beyond the extended timeline. The CDC, however, says that if there is a delay in receiving the second dose beyond 42 days, there is no need to restart the vaccination series. One can take the second dose.
After receiving the first dose, a person should not receive the second dose before the recommended time. But, it is safe to take the second dose within four days before the recommended time window.
Is it OK to Take-Two COVID19 Vaccines from Different Producers?
No, it is not. Once you take a vaccine of a particular producer, say, Pfizer, you should take the second dose of the same brand. Keep in mind that you cannot interchange vaccines of different producers in your first and second doses. It is because each vaccine is based on different formulas.
How Long Will COVID19 Vaccine Protect You?
Vaccine trial data shows that immunity in people after COVID19 vaccination lasts for several months. As Coronavirus is mutating, vaccine producers study the related characteristics and the ability to spread among people.
The producers are preparing to make the necessary adjustments in the vaccines. The CDC says that people who have already tested positive will benefit from taking the COVID-19 vaccination. But, do not disregard the mask. You should wear it even after you take a vaccine. The important thing to keep in mind is that a COVID19 vaccine is 95 percent effective, meaning about 1 out of 20 people who take it may not have protection against Coronavirus.
Another aspect to consider is that the vaccine can protect you from Coronavirus, but it is still unknown whether you can carry the virus and transmit it to others.
Therefore, it is important to wear a mask and maintain social distancing until everything is understood.
Why Should You Believe that COVID19 Vaccines are Effective?
There are enough reasons to believe that COVID19 vaccines are effective. The vaccines have passed specific tests and standards to prove their effectiveness.
Organizations like the National Academy of Sciences, the National Institutes for Health, and the Food and Drug Administration (FDA) have studied the scientific data from research before allowing the public administration of vaccines. Remember that you cannot get COVID19 after taking a vaccine, which contains proteins or other biological substances to stimulate the immune response.
Is There Any Side Effects After COVID19 Vaccine Administration?
You will experience specific side effects after you take a COVID19 vaccine. But there is nothing to worry about. When you take the vaccine, you may get pain, fever, or experience body aches, headaches, and tiredness for a day or two. Moreover, you can also experience chills and swollen lymph.
These side effects do not mean that you have become a victim of COVID19 but are indications that your immune system is responding to the vaccine.
Given the nature of the pandemic, you should not fail to take a COVID19 vaccine. Before you take it, why not explore how it works?
