Pfizer and BioNTech’s mRNA-based coronavirus vaccine in discussion these days. The company claims that the vaccine is 90% effective and now billionaire lead scientist Ugur Sahin of its developing team claims that the vaccine will hit the virus hard and end the epidemic.
However, scientists and even UK Prime Minister Boris Johnson have said that the vaccine should not be considered a panacea treatment because it has not yet been guaranteed to work.
Actually, the vaccine was tested on young and healthy people, and in this case, what will be its effect on the elderly, it has to be seen now. At the same time, Sahin says that the complete data of the vaccine can come in three weeks. He said that it will be able to stop the Kovid-19 but whether it can stop the transmission or not, the answer has not been received yet. Sahin said that the vaccine will provide protection for one year and a booster may be required every year.
Professor Andrew Pollard, leader of the Vaccine Trial at Oxford University and AstraZeneca, says the team expects the vaccine to be approved by Christmas. He says that it will be 10 times cheaper than Pfizer. Actually, the Pfizer vaccine has to be kept at a temperature of -70 ° C and two injections will be made at a difference of a few weeks. The Oxford vaccine has to be kept at fridge temperature.
