Which Covid-19 Vaccines Should I take?


 

I am not sure about you but personally, feel confused about the many types of vaccines available. It's not that we are spoiled with choices. It just a matter of what good and suitable for our body. I bet many of us want the best for ourselves and our family. Do you know that the concept now is to take as it is or wait for your turn again? 


When the Malaysian Government announced on the AstraZeneca vaccines will be a giveaway on a voluntary basis, I was sceptical. I can't make the decision at all. While all my family members snatch out the opportunities, here I am still unable to make my own decision. I just can't decide on this at all. Why? Lack of knowledge and so ignorant on getting to know what is what. At least, I want to know where is the origin of this vaccine and the success rate of the trial and much more information needed. Another consideration needed is whether this is suitable for an Asian body since we live in different climates and so on. Did I think too much? Urgh! this is tough for me.


Only now, I have the urge to get to know it further. As far as my knowledge capacity which I gathered the information from my 'google magic work'. I wanted to list it down here for the sake of my personal reference and if my list here benefits others, it will be good too.

Like I mentioned in earlier this post, this entry is for the sake of my own personal reference since I am personally confused with too many vaccines name. I don't know when will my time to get the vaccines. If the time comes, I can make a better decision on whether to take it or wait for another one.


As for the list of vaccine for covid 19 in Malaysia now, are :

1. Pfizer- BioNtech - origin US

2. AstraZeneca - origin UK

3. Sinovac - origin China

4. CanSino Biologics - origin China

5. Sputnik V - origin Russia

The list may be updated by now. 

I still need to study more about the vaccine types. The terms are too science for me.
