is like a personal trainer for your immune system, teaching your body how to recognize and fight back against the actual virus.
the COVID-19 virus has lots of spike proteins that it uses to attach to the cells in your body. Once the virus attaches to your cells, it is more easily able to infect them. So the game plan is to teach your body how to stop the virus from getting to your cells.
on how to make the COVID-19 spikes. When you get the vaccine, your cells read the instructions and start creating these spikes.
the spikes and learns how to protect against them—that way when you encounter the actual virus your body knows what to do.
Side effects from the vaccine are normal, and they normally go away in a few days. These side effects happen because your body is learning how to fight against COVID-19.
Some people are concerned about safety because the vaccine was made so quickly. Here are some of the reasons why that happened:
The technology the vaccines are based on has been around for decades. It just had to be adjusted to work on the COVID-19 vaccine.
The entire scientific world stopped what they were doing to focus on creating a vaccine. They shared their research and compared notes. Normally, research teams are pretty small.
Governments spent billions of dollars to fund research and made it a top priority. Instead of trying to apply for grants, researchers had no problem getting funding.
Hundreds of thousands of people took part in trials to make sure the vaccine was safe. One of the main challenges when testing a vaccine is finding enough people who will take part in trials to see if the vaccine works and what any side effects are. For COVID-19, there was no shortage of volunteers.
The vaccine results came back quicker than usual because there was so much COVID-19 virus spreading around the world that researchers could see very quickly if the vaccine was working or not.
Millions of people have safely gotten the vaccine since it was rolled out. Severe side effects have been incredibly rare, way lower than the risk of getting severely sick from COVID-19.
On October 29, 2021, Pfizer and BioNTech received the Emergency Use Authorization from the FDA for administering the COVID-19 vaccine in 5-11 year-olds and the CDC Director has confirmed its use. This authorization will save lives, protect our children and bring us closer to ending this pandemic.
