Which One is Better for Covid Vaccine Has Bought by Singapore?

Singapore has bought three types of vaccines Pfizer Bio NTech, Moderna and Sinovac. Both the Pfizer and moderna vaccines. Use what is described is messenger RNA technology. This involves injecting Snippets of the covid-19 genetic code into a patient, Put simply. It's the recipe. She's director production of a specific part of the virus despite protein to trigger an immune response without actually expose patient to the virus. 

Both vaccines are said to have an efficacy rate of about 95 percent. China made Sinovac on the other hand uses an inactivated covid-19 virus to trigger an immune response when injected into a patient, but there is a lack of specific results on its efficacy. The Pfizer bioNtech vaccine is already being used in Britain and the US 

Moderna vaccine only in the US as of 7 January sign of that is hit be used by any country. 

So the Sinovac vaccine from China hasn't been as widely used and as we just heard there's no conclusive study on it yet. Why do we pick that as one of the vaccines to you be used in Singapore? 

Lawrence Wong, Singapore Multi-Ministry Taskforce on Covid-19 said "Well, you have to understand that we started this process very early on as early as April. We convene an expert panel chaired by By our head of civil service to look at how we can make early purchasers of vaccines for Singapore. We have to make early bets in order for Singapore to be near the front of the queue for vaccines. And at that time there is no clinical data available from any vaccine company in terms of full-fledge information only very early stage clinical information was available from all the many vaccine candidates, they narrowed down to 35. And then they drilled down even more, to look at safety Effectiveness based on whatever preliminary data that was available then and eventually they decided on the tree and that's a tree that we have made Advanced purchasers for with the aim of building a diversified portfolio of vaccines that will be safe and effective for use in Singapore and we have three now, but that's not the end of it". 

Which is safer injecting an inactivated virus or using the genetic code of the virus?

Assoc Prof Vernon Lee, Director, Communicable Diseases Division Singapore Health Ministry, said, that I think we must understand that all the vaccines that are proved in Singapore are safe and efficacious. So we're not looking at is one, you know in a way safer than the other and so on but right now the only vaccine that's available is the divisor by one type vaccine at the same time. You will see that once an additional vaccines come on board. There will be some vaccines that can be used in certain subpopulations. For example defines the vaccine cannot be used in people who have severe allergic reaction. I cannot be used at this point in children below 16 and Pregnant women in severely immunocompromised individuals other vaccines might be able to be used in different populations. 

So we need to wait for more information and it is which vaccine is more sort of applicable or relevant to that particular population if it's offered to encourage people to get that vaccine.
