Before getting vaccinated, many individuals like to research the vaccine to better understand what it is they are receiving. Understandably, individuals want to find out information such as whether the vaccine is FDA approved, what the chemical composition of the vaccine is, potential side effects, and even who may be eligible to receive it. Ultimately, gathering information helps them to make the best choice for themselves and their loved ones.
If you’ve been interested in learning more about the Pfizer vaccine, then let the professionals at your local RGV family medicine clinic provide you with insights into the shot.
The Pfizer vaccine was formally approved by the Food and Drug Administration (FDA) in August 2021 and was the first vaccine to be federally approved to treat COVID-19.
This vaccine consists of two injections, with the second dose given three weeks after the initial shot. The Pfizer vaccine is intended to protect those 16 years and older from COVID-19.
For teenagers aged 12 to 15, the FDA has granted emergency use authorization (EUA).
Pfizer created its COVID-19 vaccine from research done on other strains of coronaviruses and mRNA technology.
Researchers began by taking the RNA-based genetic sequence of COVID-19 and turned it into DNA. Doing so allowed them to identify the steps necessary to create the spike protein. Once the spike protein was created, researchers could then engineer corresponding synthetic mRNA to put into their vaccines.
After you receive your vaccination, your body is left with T-lymphocytes and B-lymphocytes that have the capability to fight off the virus should you become infected.
Generally, it takes a few weeks for your body to fully produce these T-lymphocytes and B-lymphocytes, so it is still possible to get infected with COVID-19 during this period. It is recommended that you take precautions while you allow your body to produce these “memory cells.”
While your body is building up immunity, it can cause varying side effects. Although you may have to deal with these side effects, it’s a normal sign that your body is working to strengthen that immunity.
The side effects of the Pfizer vaccine may vary among recipients, but common side effects include:
• Pain and swelling at the site of injection
• Join and muscle pain
• Swollen Lymph Nodes
If you have questions regarding any side effects you may experience or are currently experiencing, reach out to your doctor or medical professional.
