Then the genetic material in a tiny protective bubble of fat gets into the cells. To get effective results vaccine is given in two doses three weeks apart.

How Was the Vaccine Developed?

BioNTech, a Germany-based company, has designed an mRNA vaccine after the genetic sequence of the SARS-Cov-2 virus became public. BioTech partnered with Pfizer in march, early clinical trials two leading mRNA neutralizing the antibody response that was better than recovering from natural coronavirus infection without serious side-effect.

Based on the trial, the results company has decided to move forward with the combined phase ⅔ random trials on 30 microgram doses.

To find out the ingredients causing the unpleasant reactions, NIH has started conducting a study in which people with severe allergic reactions under medical supervision.

Storage Limitation

The vaccine is needed to be kept in the cold. In fact, extreme cold is necessary to keep the RNA molecules from degrading. This requirement of cold chain poses one of the major hurdles in distributing the vaccine. Many potential vaccination sites cannot provide the ultracold freezer and have no source of dry ice.

However, Pfizer has tried to deal with the challenge by creating special thermal shippers; it maintains the ultracold temperature for up to 10 days.
