The Side Effects of Covid-19 Vaccine AstraZeneca

My threshold of pain is high. Growing up in a poor environment under harsh weather and living conditions and experiencing child labour pains made me more resistant to pain. There is no other option than to toughen up. Then came the time to have my Covid-19 vaccine. The worry is real. My threshold of pain is put to test.

I had my covid-19 vaccine AstraZeneca on 12 April 2021. Briefing was done before and after the vaccine was given. A doctor supervised the nurse administering it.

The common side effects after Covid-19 Vaccine AstraZeneca include:

  • pain, swelling, tenderness, redness and itching oat the injection site
  • tiredness
  • headache
  • muscle pain
  • nausea
  • fever and chills
  • feeling unwell
  • joint pain

The less common side effects after Covid-19 Vaccine AstraZeneca include:

  • enlarged lymph nodes
  • pain in limb
  • dizziness
  • decreased appetite
  • stomach pain

Severe allergic reaction (anaphylaxis) occur approximately 1 in a million people getting it. A very rare side effect of an unusual condition involving blood clotting and low blood platelet affects 4-6 people out of a million people. The blood clot can affect the brain and the abdomen and may lead to long-term disability or death.

This rare effect is what worried and scared me aside from my phobia of needles and injection. Sure! People keep saying that it is rare and only affects 1 in a million and 4-6 in a million. But… you never know… you might be the 1… or among the 4-6.

Osteomyelitis, a rare bone infection affects 1 in 5,000 people. And sadly, my oldest son was that 1 person among the 5,000 people. I will write about that.

So anyway, because the Covid-19 vaccine is needed in my line of work and in my health condition, I bravely went to have my vaccination.

Because of my fear of needles, I tensed my arm during the injection. So until now, the injected part is sore. I took a shower the moment we arrived home. Within the hour, I fell asleep… for the next 24 hours. Yes, deep sleep. Like totally out of it. I felt like I was under the effect of anesthesia. In the morning, I needed to go to the bathroom. It was 9:05 AM. I thought I will sleep for 5 more minutes. The next time I opened my eyes, it was 10:08 AM. I went back to sleep later and woke up at night.

24 hours deep slumber and lethargy. That is the effect of the vaccine on me. I only woke up for short intervals of time just to take my meds, to take a shower and to go to the toilet. Perhaps deep sleep is my body’s coping mechanism not to feel the pain.

I had the vaccine on Monday. On Tuesday and Wednesday, I was feverish, had muscle pain (my hips were the most painful), tiredness, lethargy, headache, stomach pain, coughing and flu-like symptoms. I took panadol (paracetamol) for 2 days but it is not that effective. I took Advil (Ibuprofen. I avoid this if I can) last night and this morning. I feel better today. I have colds. I don’t know if it’s a side effect.

I was fearful of the effect of Covid-19 vaccine on me. I requested if I could sleep on the sofa bed near our dining room, instead of in our bedroom, so my family can check up on me and see if I am still breathing or not. My second son did not sleep the whole night on the first night after the covid injection to take care of me. Poor boy! He is my nurse ever since he was young. Just now while I am writing, he asked if I am okay. I said yes. He can now study without worrying about me.

I wrote this blog because many family and friends were asking how I was and what the effects of the Covid-19 vaccine were especially for those who are still waiting for their vaccine. Thanks for your care and concern.

I can say that the effects differ from one person to another. It depends on how your body can take the vaccine. It took me 3 days before my body can recover. My husband was okay on the second day. One thing is important though. It is good to acknowledge and to validate the fear of someone on the effects of Covid-19 vaccine. After all, it is a new vaccine, no matter how many studies and tests were made, a foreign thing to be injected into your system. Who wouldn’t worry?

It is my prayer that this pandemic will end. My heart goes out to everyone who lost loved ones due to Covid-19. God bless you and your family.

  1. Halu teacher i am a covid survivor,at first i had no cough or colds but i felt body pain and heavy feeling on my chest as i breath in then came the fever,less appetite,wants u to sleep and sleep,diarrhea even water tastes bad,back pain,kung di mo pipilitin kumain matatalo ka,it took me more than a week to recover,solmux and paracetamol 3x a day and 1000 mg vitamin c yun lang sinabi ng doctor monitoring us at home via phone call. We have different brand of vaccine here in the Philippines of which isa ako sa natatakot magpa vaccine because of reported deaths due to the side effects of the vaccine.


  2. Hello! Salamat at survivor ka. Ang hirap pala ano? At iba-iba ang nararamdamang symptoms ng bawat isa at iba-iba din ang kagrabe nito.

    Reading your description sa mga naranasan mo made me imagine and understand more ang hirap ng maging covid patient.

    Marami akong kapamilya dyan na nagpavaccine na kasi frontliners sila. Yung iba, nakapagfill up ng form na pero mas maraming ayaw kasi takot nga dahil sa mga napapabalita na side effects. And the fear is understandable talaga.

    Thanks po for reading and for sharing your story. Take extra care.
