In the trial, the safety profile of the vaccine was also found to be similar to that of older people. US health officials say that regulators can make a decision on the effectiveness and safety of the vaccine within three weeks. Earlier, data from tests conducted on 2,260 volunteers aged 12-15 years found that no cases of corona infection were found after complete vaccination.

How does the Pfizer vaccine work?
The Pfizer vaccine is mRNA based in the liposomes, not the viral vector, and the mRNA has a short life and action in the host cell. The mRNA along with the liposomes will move to the host cell. It will be recognized by ribosomes in the cytoplasm instead of the nucleus. This will create a protein that is similar to the spike protein of SARS-CoV-2. It will be sent to the plasma membrane of the host cell.

higher doses needed
The immune system will see this protein and an immune response will be generated. The immune system will create a memory so that it can be dealt with later in the event of a SARS-CoV-2 infection. This sequence is fixed and the genetic material of the mRNA vaccine is unlikely to remain in the host cell for long. One problem with this type of vaccine can be that high doses have to be taken for complete protection.
