Pfizer COVID-19 Vaccine Symptoms after 1st and 2nd Dose

Posted by   on Pinterest

I would like to share with you my experience of getting the COVID-19 Pfizer vaccine and I hope this article helps you guys with the different parts of this post. I am really grateful to be among one of the healthcare workers who are able to receive our first dose of the COVID-19 vaccine back in December of 2020.

I want to give a big shout-out to all of the health workers who are working tirelessly both in the hospital as well as in the vaccine clinic for making this project possible. The Pfizer COVID-19 received emergency use authorization from the FDA on December the 11th of 2020.


So within a week after the 500 vaccine received emergency use authorization from FDA. I received a notification from a mission hospital in mission Viejo California that I was prioritized to receive the vaccine. I was assigned to a vaccination station at the station I was presented with a few papers letting me know some possible physical symptoms I may develop after receiving the vaccine.

Symptoms after Receiving the COVID-19 Vaccine 1st Dose

After reviewing all of the papers and I received my vaccine in my left arm around the deltoid region and it was a really nice shot. I barely felt the needle after receiving my vaccine. I stayed for about 15 minutes or so after the vaccination to make sure that I did not develop an acute allergic reaction before I was discharged.

So I received my vaccine around nine o'clock in the morning for the six and half hours after that I did not really have any symptoms however around 3:30 in the afternoon I started noticing there's some soreness in my left arm and gradually throughout the afternoon and into the evening the soreness in my left arm extended to the left side of my neck. I would say the stiffness in my neck, as well as soreness in my arm, peaked around midnight.

During the night I woke up a couple of times and noted significant neck stiffness in the arm soreness. I was prepared to take some Tylenol or even Advil If the stiffness and pain persist but I was able to fall back asleep in the morning when I woke up most of the arm pain and neck stiffness have improved however it was still quite noticeable.

I was actually quite glad that I did not have any cases on or that day. Throughout the second day after my vaccination by the time, the evening comes to the arm soreness and neck stiffness mostly went away.

So it is very interesting I never developed any fever or chills or other symptoms reported by the vaccine recipients in the clinical trial. Everybody is different so when you get your covid-19 vaccine you may develop similar or completely different types of physical symptoms I look forward to hearing from your experience in the comments down below. 

So it has been about three weeks since I received my first dose of physical the covid-19 vaccine. I didn't really develop any new physical symptoms since the arm soreness and neck stiffness subsided on the day after my first vaccination.

COVID-19 Pfizer Vaccine Symptoms with 2nd Dose

I am actually scheduled to receive the second dose of my vaccine tomorrow because I developed my significant arm soreness after the first dose I blocked off my schedule after my second dose of vaccine to make sure I'm not operating the day after receiving my second dose of Physio vaccine I received the second dose of the Pfizer vaccine.

After receiving the COVID-19 vaccine during the second week of January about three weeks after I received my first dose and during that three weeks I didn't really experience any additional physical symptoms for my appointment for my second dose of the vaccine I arrived a few minutes before my appointment time my vaccination appointment went quite smooth from the second dose of my vaccine very similar as when I received my first dose.

I completed a checking process and I was assigned to a vaccination station I completed some papers there and nurse Susan gave me my second dose of the COVID-19 vaccine the actual injection was painless and we were both very excited because now I have completed my two doses of the physical vitamin 19 vaccine so now I am fully protected.

I waited about 15 minutes after receiving the vaccine to make sure that I did not develop any allergic symptoms before I was discharged and through for the rest of the day.

I actually worked a regular schedule I saw patients in the clinic for the whole day. It was very interesting I actually did not notice any pain in my left arm where I received the injection for the whole day. Starting at nine o'clock in the evening I started feeling feverish and I started getting some chills I actually had a low-temperature fever of 101.1 and I checked my o2 saturation which was normal.

I was a bit tachycardic I had a bit of fast heart rate and I felt really tired so I went to bed early and throughout the night I actually did not sleep well because of the fevers and chills that I was having.

I felt pretty cold throughout the night when I woke up in the morning now it's about 24 hours after I received the second dose of my vaccine. I had a headache throughout the whole day I felt really tired and I pretty much spent the whole day on the couch. I was really glad that I took the day off the day after I received my second dose of the vaccine because I just felt so tired the whole day.

I was not productive at all I pretty much just did some paperwork some computer work on the couch throughout the whole day and I went to bed very early around 7:30 in the evening.

Because of the fatigue that I experienced and I also had some muscle achiness. It was interesting because I had muscle ache in both legs. I did not have much arm pain around the injection site.

So after I woke up in the morning now it's about 48 hours after I received the second dose of vaccine. All of my symptoms were gone actually I felt like nothing has happened. All of the physical symptoms that I was experiencing the day before resolved completely.


to summarize after I receive the first dose of my Pfizer COVID-19 vaccine I actually had pain in my left arm as well as the left side of my neck for about 36 hours after receiving the first dose of vaccine.

After receiving the second dose of the vaccine I experienced more intense physical symptoms. I had fever chills, fatigue, muscle ache, and headache. Which were all common symptoms reported in the clinical trial however all those symptoms actually resolved spontaneously after 48 hours after receiving the second dose of the vaccine.

So all the physical symptoms that I experienced as well as the physical symptoms reported in the clinical trial. Those are actually common symptoms that people may experience after having an activation of their immune system due to the inflammatory response from it.

There's a scientific term describing those physical symptoms is called reactogenicity which covers the group of physical symptoms that can occur shortly after receiving vaccination due to the immune system activation and the inflammatory response that comes with it.

So it is expected after receiving the COVID-19 vaccine for you to experience some physical symptoms as that's basically a sign the immune system of our body is working and is actively producing antibodies to protect ourselves against future infection.
