Are we getting vaccine : Pfizer and Moderna

A year is going to be passed since covid-19 pandemic start and we are still finding a good vaccine against covid-19.
But this month we get good news regarding covid 19 vaccine. USA's two vaccine developing companies are claiming that their vaccines are helpful to immune people from covid-19.
On November,09 first company whose effect is more than any other vaccine came. Pfizer is showing vaccine results more than 90 percent. Pfizer is making vaccine in collaboration with Germany’s BioNTech SE. Pfizer's vaccine is the first vaccine than any other vaccine found such results.
UK has pre-booked million of doses, which will be provided to them by Christmas. But Pfizer’s administration said the vaccine will be going to help the world to recover.

Another vaccine which shows 95 percent effect against Corona virus is #Moderna, a US based pharma company developing in collaboration with US medicals.
The trial has been provided to around 30 thousands participants, which shows good effect on them and Moderna is ready to produce doses in high volume for vaccinating people.
After both the companies' good results, still it is not clear how this will react to normal being and how long will it protect from virus or another reason will they stop virus from spreading or only protect the person from coronavirus disease.
The main difficulty will be getting vaccine available to people’s hand. Both companies' vaccine is MRNA based which need deep freezing before injected.
In last both the vaccine are giving some hope to us towards getting back a normal life. We all may be vaccinated by next Christmas or not but till then we all have to follow the precautions towards coronavirus pandemic in order to protect ourselves.
