Modernna vaccine or Pfizer - BioNTech? Which is better and why

Both vaccines are very similar, but they have some major changes that make Modernna “more flexible”, as said American Health and Human Services Secretary Alex Azariah.

Efficiency: Both vaccines, Modernna and Pfizer - B NTech have shown similar levels of efficiency of nearly 95%.

The “appears to be roughly equivalent,” said Dr. Paul Offi, a member of the FDA vaccine advisory committee, during a presentation in “CNN's Day” on Tuesday.

The structure : Both vaccines rely on the ARN, or the sending RNA, though with slightly different structures and compositions, translates Periscopi.

Here's what we know about Pfizer's vaccine, including which age can get first.

Cold magasing: Most importantly, the Moderna vaccine does not need to be kept in very cold temperatures, such as Pfizer's.

Pfizer vaccine should be preserved at about minus-75 degrees Celsius, about 50 degrees colder than any vaccine currently used in the US. The vaccine can only enter the refrigerator for five days before it expires.

To accommodate it, the CDC created a complex group of treatment and storage requirements known as “cold engineering” that included expensive ultra cold freeze and very dry ice.

On the contrary, the Moderna vaccine can be held at about minus 20 degrees Celsius, or in connection with the temperature of a refrigerator in the home, according to Moncef Slaui, head of the US effort to develop a vaccine for Ovid-19. The Moderna vaccine can also be kept in the refrigerator for 30 days before it expires.

So this is more manageable and much more available,” Slawi said on Tuesday.

These changes suggest that Pfizer vaccines can be used more for major institutions with infrastructure established as hospitals, while Modernna may be more useful for smaller objects as a local chain or a pharmacist.

Dozim and Time: The Modern Vacina is administered as two 100 microgram doses given 28 days by difference. Pfizer's vaccine is administered as two 30 microgram doses, separated 21 days.

Age: If authorized, the Modern vaccine would be used in people 18 and more, while Pfizer vaccine was authorized for persons 16 years of age and older./ P ERISCOPI/
