Everything You Need to Know About COVID-19 Vaccine

Updated: 3 days ago

We’ve come really far in learning about the novel coronavirus with different vaccines being rolled out across the globe. We come across new information every day about both the vaccine and the virus. Here’s everything we know about the COVID-19 vaccine.


What We Know


Research shows that COVID-19 vaccine can prevent you from contracting COVID-19. Even if you get the coronavirus after getting the vaccine, it can prevent you from developing severe symptoms.

The COVID-19 vaccine enables your immune system to recognize and combat the coronavirus. It usually takes fourteen days after getting a vaccination for your body to get build immunity against the virus.

This means that a person can get sick if they contract the virus before their vaccine could build immunity against it. Vaccines that have been rolled out so far include the Johnson & Johnson’s Janssen vaccine, Moderna, Pfizer-BioNTech vaccine, and various Chinese and Russian vaccines.

Therefore, until you’re vaccinated with both doses of two-dose vaccines, you need to take precautionary measures to curb the spread of COVID-19.


What We Don’t Know


While COVID-19 vaccines are great at combating the virus, researchers are in the process of learning whether they prevent the virus’s spread or not. The answer to this would be clear as more and more people get vaccinated. Scientists are also learning how long a vaccine can protect people from contracting the coronavirus.


Until then, those who are vaccinated must continue to follow precautionary measures.


How Does the Vaccine Work?


As opposed to regular vaccines that inject a small amount of the disease germ (virus or bacteria), COVID-19 vaccine introduces an inactivated part of SARS-CoV-2 to our immune system. While this doesn’t give us COVID-19, it can prepare our body to develop antibodies to ward off the virus if it tries to infect us in the future.


Different coronavirus vaccines work in their own way to protect us, but all vaccines leave our body with memory cells (B-lymphocytes and T-lymphocytes) that create a memory of SARS-CoV-2 in our immune system and remind it how to fight the virus in the future.






Are COVID-19 Vaccines Safe?


Thousands of people across the US have gotten the COVID-19 vaccine. The CDC has formulated a safety tool called V-Safe. It’s a smartphone app for people who have gotten vaccinated to check if they are experiencing any side effects.


Some people do get side effects after getting vaccinated, such as tiredness, chills, or soreness in the arm.
