Certainly the situation on all fronts is changing, sometimes quite quickly. For now, the Pfizer is thought of as "better" because there are a small number of cases concerning the AstraZ, chiefly of course centred around blood clotting. But the numbers need to be understood and need to be put into a human context. In numerical, mathematical terms, a 0.0004% chance is worse than 0% chance, but the difference is so small that in real world usage the risks are pretty much the same IMO. There also seem to be issues around the accuracy and completeness of record keeping and data collection, which will hopefully improve in the future.

If you're starving and walking down the road, you don't walk past 1000 2 Michelin star restaurants in the hope of finding a 3 Michelin star, even though the latter may be "better." So whilst we may all prefer the Pfizer (for peace of mind etc.) the difference between the two is not nearly as big as is made out to be, and IMO is being blown out of all proportion.

(05-23-2021, 09:50 AM)LP link Wrote:Novavax, AstraZeneca and J&J are basically made by the same method.

They deliberately infect a vector of some sort and then collect the proteins needed to form the vaccine, in the Novavax case they use a virus and moths.

In the case of the virus vectors, AstraZeneca and J&J use Adenovirus, Novavax use Baculovirus.

The media is saying one is more dangerous than the other, the politicians obey public opinion and act based on politics and polls.

The truth is the scientific studies have shown them to be equivalent in all aspects, but you choose to believe the media / social media.
